326 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARI#: 
out within the margin, depressed towards the suture; punctate-striate, strie eight and 
a half in number; the stria next the suture broader, being double at the base; last 
external stria beyond the shoulder deepest in the middle; the stris are effaced a little 
before they reach the apex, which is then irregularly punctate; the interstices are most 
faintly punctate in rows; the red patch near the apex is somewhat conical in shape, 
. leaning outwards, and its base (the side next the apex) truncate and parallel to the 
apex, which is obliquely truncate; the sutural apical angles are right-angled, slightly 
sinuate; the exterior apical angles are rounded. The abdomen is closely and finely 
acicularly punctate. Underside of abdomen more coarsely (almost subrugosely) aci- 
cularly punctate, the last three segments each with a large fovea on each side, which is 
not present in the first two. Underside of thorax ferrugineo-piceous. Thighs and tarsi 
ferrugineo-piceous ; tibi: nigro-piceous. 
A unique specimen in the British Museum. 
Collected by Mr. Bates near Ega, on the Amazons. Found flying over dead trunks of 
trees in sunshine in the driest weather. 
2. HALEPOPEPLUS ERYTHROPYGA. 
Valde affinis H. bipustulato; niger, capite linea transversa, elytris singulis macula 
apicali et abdomine pygidio rubris; ceteris fere ut in H. bipustulato. Long. 3$ lin., 
lat. 14 lin. 
Habitat apud flumina Amazonum. 
Very closely allied to .H. bipustulatus, perhaps one of its sexes; but as I have only seen 
single specimens of each, it is premature to say. It is rather narrower; the head is not 
so broad; the thorax not so much dilated, and consequently rather larger; the elytra 
are each more convex and more depressed towards the suture, and the sutural stria is 
more punctate; the red patch at the apex of each elytron is rather larger, and the last 
segment of the abdomen is wholly red instead of black. In other respects it is almost 
identical with Z. bipustulatus. 
From the Amazons. Found under the same circumstances, flying in the sunshine 
over dead timber. 
3. HarEPOPEPLUS Baresi. (Plate XXXV. fig. 1.) 
Valde affinis ZZ. bipustulato; aurantiacus, elytrorum limbo atque abdomine (segmento 
ultimo excepto) nigris. Long. 32 lin., lat. 14 lin. 
Habitat apud flumina Amazonum. 
Nearly allied to H. bipustulatus. Bright orange-coloured, with the margins of the 
sides, the apex, and the abdomen, except the last segment, black. The impressions on 
the head are united into a large, transverse, deeply punctate impression across the head, 
behind the labrum. Thorax more rounded, more emarginate in front, more shining, and 
finely punctate. Elytra less depressed towards the suture; the striæ effaced further from 
the apex than in H. bipustulatus. In other respects this species does not appear to 
differ from it.
