288 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
The Brachypepli proper may be divided into those 
A. With the lobes of the ligula rounded—South American and Caffrarian species. 
B. Those with them not rounded (elongate, concave, &c.)—Asiatic species. 
Which last, again, may be divided 
a. Into those with a transverse quadrangular scutellum—Bornean and Malayan species, 
B. And those with a transverse but not quadrangular scutellum— East Indian species. 
(Subgenus ONICOTIS (owxóc and oic, eared like an ass).) 
Corpus sat convexum, fere glabrum, lateribus fortiter ciliatis.  Antennz articulo basali valde dilatato. 
Mandibule late, compresse, dilatate, dente subito exserto. Ligula lobis curtis circumplicatis. 
Abdomen segmentis 1mo et 2do brevibus. 
Body somewhat convex, oval, almost glabrous, with a dense stiff fringe of hairs all 
round the sides both of thorax, elytra, and abdomen. Antennze with the basal article very 
largely developed, as in Amphotis, but to a greater extent (Pl. XXXIV. fig. 10 a), and 
fitting into a vacant space in front of the eye, so that the profile of the head when the 
antenne are retracted is continuous; the remaining articles as in the other species of 
Brachypeplus. Labrum transverse, with a notch on each side of the middle. Mandibles 
broad, flat, with a short sharp tooth, slightly serrated behind, projecting abruptly 
from the broad margin (Pl. XXXIV. fig. 10 g). Maxille and maxillary palpi as in 
other Brachypepli. Ligula with short membranous lobes, which are apparently folded 
upon its front and back (Pl. XXXIV. fig. 10 e). Mentum broad, bi-emarginate. Labial 
palpi with the second article longest, and third subconical. Eyes triangular above, 
rounded beneath, and margined above by a narrow segment of the head separated from 
the rest by a deep groove, so as to look like an eyelid; the basal article of the antenne, 
lying in front of the eye when at rest, protects it. Thorax narrowest in front. Scutellum 
triangular, its apical angle rounded. Elytra costate. Abdomen as broad as the elytra, 
with the pygidium rounded; all the segments margined, the first and second consider- 
ably shorter than the rest; fimbriz simple and parallel, small on the pygidium. 
l. DRACHYPEPLUS AURITUS. (Plate XXXIV. fig. 10.) 
Elliptico-ovalis, convexus, nitidus, ferrugineo-piceus, elytris nigris; capite et thorace 
partim fortiter punctatis, partim levibus; elytris crenato-striatis ; abdomine leviter 
punetato. Long. 2$ lin., lat. 14 lin. 
Habitat in Australia in nidis apum. 
Elliptic-oval, convex, shining, ferrugineo-piceous, with theelytra black. Texture above 
rather hard, below flexible and elastic. Head with two large foveze on the inner side of 
each eye, leaving a prominent smooth nasal ridge in the middle; a few punctures behind. 
Thorax convex, smooth, with a few punctures, chiefly in patches, which are for the most 
part in foveze or depressions; the punctures made as if from behind forwards ; there is a 
double ovate fovea on each side of the middle in front, another on each side behind, more 
apart, and another, less deep depression along the margin backwards from the anterior 
angle ; slightly emarginate and bisinuate in front, sides sloping forwards and rounded-in in
