204 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
26. BRACHYPEPLUS CAUDALIS. 
B. apicali valde affinis; prothorace paulo magis transverso, minus convexo, Fig. 70. 
lateribus versus angulos posticos magis explanatis; lete flavus, capite E5 
saturatiore; elytris totis nigris, basi et regione scutellari exceptis ; ceeteris 
ut in B. apicali. Long. 1% lin., lat. 3 lin. 
Habitat in insula Batchian. 
Very closely allied to B. apicalis. It has the thorax less convex and a little shorter 
and more transverse, the sides towards the posterior angles more explanate, the punc- 
tures deeper, and the pubescence less. Clear yellow, with the head a little darker, and 
the elytra wholly black, except a triangular space from behind the shoulders to the 
suture, reaching to about the middle of its length; the margin also is pale to the very 
apex. Itisas ifthe black apex in B. apicalis had extended obliquely up towards the 
shoulder; the transverse punctuation in the interstices of the elytra is deeper than in 
that species. In other respects it corresponds with it, and is no doubt its representative 
in Batchian—the different islands of the Malayan Archipelago having often representa- 
tives or varieties of the species found in other islands. 
Collected by Mr. Wallace in the island of Batchian. 
(Subgenus LEIOPEPLUS (Acioc, smooth; rér\oc, robe).) 
Corpus depressum, elongatum, nitidum, haud vel vix pubescens. Thorax marginibus haud ciliatis, Ligula 
lobis curtis, sat densis. Abdomen postice haud cuneatum. 
Body depressed, elongate, scarcely, if at all, pubescent, shining, and of a harder texture 
than most of the other species. Thorax not ciliated on the sides. Ligula with the lobes 
expanded somewhat similarly to those of Carpophilus, rather thick, and densely ciliated 
all over the surface. Scutellum transverse, triangular or pentangular (see fig. 73). Ab- 
domen not wedge-shaped behind. Fimbrie rather broad, sinuate on the pygidium, widest 
behind on the other segments, with a raised tubercle (behind which the stigmata lie) in 
the hollow of their curve.

gineus, capite elytrorumque apice nigris; elytris rugose punctato-striatis, [d 
striis haud apicem et marginem attingentibus, interstitiis leviter, apice et ( / 
margine dense et rugose punctatis. Long. 34 lin., lat. 1 lin. 
Habitat in Calabaria antiqua in Africa occidentali. 
Elongate, rather broad, flat, depressed, shining, bright rufo-ferruginous, with the head, 
the apex of the elytra, and the tip of the pygidium black; punctate; elytra punctate- 
striate, Head thickly and finely punctate, bi-impressed in front, leaving the epistome 
like a nasal ridge in the middle, and on the outer side of the impressions another 
raised space on each side. Mandibles and maxille ferruginous. Thorax transverse ;
