MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 253 
l. CALONECRUS WALLACEI (Plate XXXII. fig. 9.) 
Thomson, Arch. Ent. i. 117. pl. 10. fig. 3 (1857). 
Elongatus, supra depressus, subnitidus, punctatus, pubescens, rufo-ruber ; antennis, elytris 
pedibusque cyaneo-nigris; thorace basi quam apice latiore; elytris angulis posticis 
anguste incisis, hine dente acuto extus retro projiciente. Loh: 4-5} lin., lat. 1-2 lin. 
Habitat in Sarawak. 
Elongate, above depressed, somewhat shining, pubescent, rufous-red. Antenne, elytra, 
and legs black, or bluish black. Head lightly punctate. Thorax elongate, sparingly and 
faintly punctate, shining, narrower than the elytra, with the sides angled in the middle, 
making it nearly hexagonal, apex straight, base slightly bisinuate, the sides both before 
and behind the middle angulation strongly sinuate, but less so in the females (?) than in 
the males, anterior angles obtusely rounded, posterior obtusely right-angled, unequal on 
the surface, being wavingly depressed both before and behind the middle and on each 
side. Scutellum punctate. Elytra strongly but not very closely punctate, the punctures 
deepest towards the suture, widest a little before the middle, shoulders projecting, de- 
pressed transversely behind the shoulders and scutellum, longitudinally on each side of 
the suture, on the disk behind the first depression, and transversely at the apex, clothed 
with a long fine brownish woolly pubescence, thickest upon the shoulders and haunches ; 
the sides turned in upon the abdomen, and broadest opposite the posterior coxæ, slightly 
margined ; the suture for about two-thirds towards the apex has a well-marked sutural 
stria; apex truncate, slightly rounded, exterior apical angles with a narrow notch cut 
out, causing the outer side to appear like a large tooth projecting backwards, sutural 
angles rounded. Below finely punctate* and pubescent. Legs punctate. Tarsi short 
and small. Males (?) smaller, narrower, and with the sides of the thorax more sinuate 
than in the females. | 
From Sarawak. Collected by Mr. Wallace, as already mentioned, in the thick gum of 
a species of Dipterocarpus. 
Mr. Wallace found, in company with this insect, a larva which he (doubtless correctly) 
refers to this species. A description and figure of it will be given in the chapter to be 
devoted to the larvee of this family. 
2. CALONECRUS LATICOLLIS. 
Valde affinis C. Wallacei, thorace planiore et latiore, apice quam basi paulo latiore, 
lateribus vix sinuatis; elytris pube cirratis, angulis posticis minus incisis et dente 
exteriore minus acuto; rufus, antennis, elytris pedibusque nigris. Long. 4j lin., 
“lat. 2 lin. 
Habitat in Sarawak. 
Nearly allied to C. 77011662. It is duller, broader, and the thorax and elytra are 
flatter and more depressed. The thorax is nearly hexagonal, but it is a little broader at 
the apex than at the base, while in C. Wallacei it is decidedly and considerably broader 
* M. Thomson, in his description, says that the pygidium and underside are smooth (lisse) ; but in all the species 
they are decidedly punctate, although less deeply than on the thorax and elytra.
