Mymar pulchellus is, without doubt, the most extraordinary of the whole family. My first specimen I caught in a spider’s web when living near Finsbury Park. It was very much held by viscid globules, but after many hours’ work appeared in Canada balsam a splendid mount. No insect has exercised my power of thought more than this one; but its life history remains a mystery still, though I imagine I am within measurable distance of discovering its nidus. The posterior wings are abnormal--mere bristles--and yet they are of immense service when hooked into the anterior ones, the black specks just before the tips of these bristle-like wings being the three hooklets. The next representative, Cosmocoma, is Haliday’s Polynema, which, he states, affects the eggs of the cabbage butterfly. C. fumipennis is of the most strikingly beautiful character. I once saw the male of this, but it was on the glass outside the greenhouse, while I was inside and the door was locked. My feelings at that moment can be better imagined than described. Caraphractus cinctus has received a good deal of attention and notoriety from the fact that in 1862 Sir John Lubbock discovered that it was aquatic in its habits, using its wings for swimming under water. It was christened Polynema natans by the worthy discoverer of its natatorial habits; but in 1896 it fell to my lot to prove it to be identical with Haliday’s Caraphractus. Anaphes is found in almost any garden, and is frequently confounded with Eustochus, but the solid club is an unfailing character. It is also somewhat larger than Eustochus. Anagrus contains many species of very delicate yellow fairy flies, always present in gardens and about ponds--in fact, almost everywhere. I have been again fortunate in discovering the life history of several species belonging to this genus. One is parasitic in eggs of dragon-flies, and three others in different kinds of eggs of frog-hoppers, which have for over thirty years eluded my search. One more genus remains to be noticed, and it is the most fairy-like of all the Mymaridæ, viz., Camptoptera papaveris. It is the smallest of the family, the female being but one-eighty-fifth of an inch long. Mystery surrounds this gem, and yet it is most plentiful in certain localities. The male, of which I have only taken two specimens, measures just one-ninety-second of an inch from head to tail, and yet is absolutely perfect in every part. INSECT TRANSFORMATIONS --ANDREW WILSON Most people are aware, as a piece of commonplace knowledge, that many animals, before arriving at their mature or adult state, undergo a series of changes in form, of a more or less complete character. To such a series of changes the naturalist applies the term “metamorphosis”; and the study of the disguises which an animal may in this way successively assume forms one of the most interesting and fascinating subjects that can attract the notice of the observer.
