324 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
Elongate, linear, very much depressed, irregularly punctate, somewhat shining, ferru- 
gineo-rufous. Head shorter than in O. fuscipennis, flat, irregularly and rather thickly 
punctate ; eyes larger than in most of the other species; epistome apparently with four, 
but in reality with six, small teeth on the margin, caused by five slight emargina- 
tions (fig. 88). Thorax longer than the head, very much depressed, with a longitudinal 
smooth depression in the middle scarcely punctate; on each side of this there is a 
slight longitudinal elevation, and, again, on each side of these a less marked depres- 
sion; on the outer sides of these the surface is more deeply punctate, punctures mostly 
elongate ; the sides are nearly parallel and straight, slightly declinate, more so in front; 
anterior angles nearly right-angled, posterior angles rounded; apex straight, base some- 
what rounded, the edges of both a little turned up. Scutellum shining, impunctate. 
Elytra testaceous or livid testaceous, with the apex more or less livid brown, very little 
longer than the thorax, parallel, hollowed towards the suture and scutellum ; humeral 
angles distinct; sides straight when seen from above, but slightly declinate and inflexed, 
and, seen from the side, a little widest behind the middle; punctate-striate, the interstices 
impunctate; apex with the exterior angles rounded and sloping obliquely to the suture, 
but when near the suture becoming truncate; sutural angles right-angled. Abdomen 
ferrugineo-rufous, with the pygidium somewhat piceous; the fimbris very strongly | 
marked; a slightly raised longitudinal line in the middle of the penultimate and ante- 
penultimate dorsal segments. Legs testaceous. 
This stands in some collections as Laporte's Cilleus filiformis, but it is obviously 
different—being glabrous, while his species is described as pubescent. 
From Nicobar. In the Hope collection at Oxford; also in the Copenhagen collection 
and in the British Museum. 
Genus HALEPOPEPLUS (xaXezóc, hard; rér\oc, robe). 
Caput sulcis antennariis convergentibus. Labrum simplex, transversum. Epistoma leviter porrectum, 
subconvexum. Thorax basi et angulis rotundatus. Prosternum prominens. Elytra striata. Abdomen 
thorace longius, segmentis primo et secundo brevioribus, tertio et quarto majoribus, quinto maximo, 
supra segmentis ultimis tribus expositis; fimbriis modicis, subparallelis. Tibia apice vix canali- 
culatze. 
Body long, subconvex, subdepressed on the disk. Texture hard. Head rather large 
and broad. Epistome broad, only slightly projecting. Eyes rather small. Antennae 
with the first article enlarged, second small, third longer (second and third as long 
as the five following), fourth to eighth small, gradually increasing in breadth, ninth to 
eleventh forming the club, of which the ninth occupies the greater part ; club roundish. 
Antennal grooves distinct, short, and converging. Labrum transverse, slightly emargi- 
nate in the middle. Mandibles with a simple point, not toothed behind. Maxillary lobe 
rather broad, with the apex oblique and terminated by a fringe of long hairs, but with- 
out any on the inner side. Maxillary palpi somewhat longer than the maxillie; first 
article minute, second somewhat pyriform, third short, fourth cylindric conic. Ligula 
corneous, with a broad, ciliated, membranous lobe, apparently double, on each side 
(Plate XXXV. fig. 1e). Labial palpi with the first article small, the second tumid and
