too long for this occasion; neither would it be proper for me to enter farther into an account of them, as that gentleman purposes to treat minutely on their various histories in his Voyages and Travels: a book which, he informs me, is in some forwardness, and will doubtless afford great entertainment and information to the curious part of mankind." RAPHIGASTER VALIDUS. Plate XXXVIII. fig. 4. ORDER: Hemiptera. SUBORDER: Heteroptera. SECTION: Geocorisa, _Latr._ FAMILY: Scutati, _Burm._ Pentatomidæ, _Leach_. GENUS. RAPHIGASTER, _Laporte_. RAPHIGASTER VALIDUS. Pallidus, capite, pustulis duabus pronoti et dentibus lateralibus obtusis, scutello (apice excepto) elytrisque chalybeis, abdominis lateribus nigro maculatis. (Long. Corp. 1 unc.) SYN. Cimex variegatus, _Drury_, _App. vol._ 2. Cimex validus, _Drury_, _App. vol._ 1. (_pl._ 45. _fig._ 6. _eadem_). _Klug. Burm. vol._ 2. _p._ 365. Edessa Tarandus, _Fabr. Ent. Syst._ 4. 93. _Syst. Rhyng._ 147. HABITAT: Jamaica. Head dark mazarine blue, and small. Eyes and antennæ black. Thorax cream-coloured, with two large blue spots upon it; each of its sides being armed with a strong blue spine. Scutellum triangular, and dark blue, the extremity cream-coloured. Abdomen red, with black streaks crossing its margin. Hemelytra blue half way, the other half opake and brown. Wings membranaceous and brown. Rostrum black. Under side of the insect red (except the extremities of the legs, which are black), having four triangular black spots running down the middle, and some others placed on the sides. This fine insect was noticed in the synoptical appendix to the second volume, under the name of Cimex variegatus, the same name having been also inadvertently applied to the insect figured in Vol. I. Pl. 45. Another figure of the same insect, but with the wings closed, is given in the third volume, Pl. 45. Fig. 6. in the synoptical appendix of which volume it is noticed, under the name of Cimex validus. It is therefore probable that our author was not aware of the specific identity of the two figures. To avoid the inconvenience arising from having two species bearing the same name, Cimex variegatus, I have adopted the name proposed in the third volume. TETTIGONIA SANGUINEA. Plate XXXVIII. fig. 5.
