This is another small group containing few species, but _Lagria grandis_ is one of our very common beetles, and can be collected on low scrub anywhere about Sydney. The larvae are to be found under logs or among damp leaves on the ground, and are thickset, black, shining creatures. covered with short reddish hair on the upper surface; short antennae standing out in front; and the tip of the abdomen is produced into a pair of pointed spines. The beetle is light reddish brown, closely covered with fine confluent punctures and short scattered brown hairs. It is slightly over ½ an inch in length, with a small head, slender, narrow thorax, and with the front of the wing covers forming a broad shoulder in front. Family 41. ANTHICIDAE. These are small ant-like beetles, with the head having a regular neck and the thorax narrow and elongate; most of them are found among rubbish upon the ground, or along the edges of creeks and watercourses. It is chiefly owing to the researches of King, who collected and described a great number of the species found about Sydney (Trans. Ent. Soc. N.S.W. 1869), that we know much about this family. Family 42. PYROCHROIDAE. This is a small group containing some beetles with the head attached to the thorax by a neck, and with the wing covers much broader than the thorax: _Lemodes coccinea_ is a pretty little bright red beetle with black legs and antennae, the latter tipped with white; it measures slightly over ¼ of an inch in length; is common under logs in the Illawarra district. Another species, _L. splendens_, has recently been described by Lea (Pro. Linn. Soc. N.S.W. 1906) from specimens obtained by me at Noundoc, N.S. Wales. Family 43. Pintails. MORDELLIDAE. This group, in which the _Rhipidophoridae_ are now included, are very distinctive beetles; they have the head tucked down in front; the thorax large, broad, and rounded at the base, with the hind margins angular and fitting closely into the wing covers, which taper down to the apex; the end of the abdomen forms a stout spine-shaped tip extending beyond the wings.
