MALACODERMATA. . 319 
having the sides of the thorax yellow and the legs entirely bright yellow; and is 
apparently a shorter and stouter insect. 
2 (s). Attalus tabogensis. | 
Pallide flavus; capite prothoraceque nitidis, hoc disco, illo basi nigro-piceis; elytris opacis, pilosellis, vitta 
fusca; antennarum et tarsorum apicibus infuscatis. Long. 24 millim. 
Hab. Panama, Taboga Island (Champion). 
Allied to A. limbatus, and chiefly distinguished from that species by the very pallid 
and opaque elytra, which are often quite pale, with the exception of an elongate infuscate 
patch towards their apex, at other times they are dark fuscous with pale suture and 
margins. The head is usually yellowish as far as the middle of the eyes, but in one or two 
examples it is nearly all black, but even in these (which have at the same time blacker 
elytra) these latter are opaque. The male has the tip of the elongate second joint of 
the tarsi black. The female has the apex of the pygidium semicircularly cut out, and 
fringed with long hairs on each side. The male has a deep and long impression on 
the abdomen above, near the apex, extending over the greater part of the last segment. 
About a dozen examples were obtained by Mr. Champion on flowers in the hot sun 
on the rocky slopes of the island of Taboga in company with other minute and inter- 
esting allied species. ) 
2(c). Attalus fuscescens. 
Niger, nitidus; elytris ultra medium fusco-testaceis, antennarum basi, ore pedibusque testaceis, tarsis apice 
nigris ; abdomine piceo, segmentis singulis albido marginatis. Long. 23-3 millim. 
Hab. Panama, Taboga Island (Champion). 
Head and thorax pitchy black and glabrous, the latter about as wide as long, and 
equal to the former in width; antenne shorter than in A. caraboides, and darker at 
the tips, the three or four joints at the base yellow. Elytra not much widened behind, 
nor very convex, clothed with a very short fuscous pile; black at the base, and at about 
one third of their length shading insensibly into dirty pale livid-yellow. Legs yellow, 
the tips of the tarsi only blackish; sometimes the femora are infuscate. I have not 
detected a male, and therefore cannot affirm this to be a true Attalus. It is apparently 
_ allied to A. caraboides, but no such structure as I noticed in the trochanter of that 
species can be found here. Hight examples captured by Mr. Champion “ on flowers in 
the hottest sun.” 
2 (p). Attalus (?) calearatus, (Tab. XIII. fig. 3.) 
Niger, nitidus; pedibus rufis, femoribus posticis piceis, abdominis lateribus, segmentorumque singulorum ~ 
marginibus luteis; tibiis posticis ad apices calcarato-productis. Long. 2 millim. 9. 
Hab. Panama, David, Tolé (Champion). 
Very closely resembling A. nigrowneus, but smaller, and with shorter antenne, and
