222 ME. M. JACOBY ON" PHYTOPHAGOUS COLEOPTERA [Mar. 6, 



head and thorax finely and closely punctured, the latter with 

 a smooth central line ; elytra extremely finely punctured and 

 wrinkled, clothed with short silvery pubescence. 



Length 5 rnillim. 



Of obscure brownish-aeneous colour, the head finely and sub- 

 remotely punctured ; the clypeus not separated, punctured like the 

 head ; labrum piceous, lower joints of the palpi fulvous ; antennae 

 short, not extending to the middle of the elytra, dark fulvous, the 

 basal joint stained with aeneous, terminal joints distinctly 

 thickened, each stained with fuscous at the apex ; thorax strongly 

 transversely convex, the sides rounded, the surface closely and 

 finely punctured throughout, clothed with very short white pubes- 

 cence, the middle of the disc with a smooth central narrow space, 

 all the margins very narrowly metallic cupreous ; scutellum much 

 broader than long, its apex blunt, the surface with a few punctures, 

 the margins cupreous ; elytra not wider at the base than the 

 thorax, very slightly depressed below the base, opaque, extremely 

 closely punctured and finely wrinkled, the interstices with still 

 smaller punctures and clothed like the thorax with short whitish 

 pubescence ; underside and femora dark aeneous and sparingly 

 pubescent ; tibiae dark fulvous. 



Hab. Pinetown, Natal. 



This is the description of the male insect, which has the 

 anterior legs as usual longer than in the female ; this and the 

 rather less broad thorax, however, are the only visible differences 

 between the two sexes. C. alutaceum differs from the other 

 pubescent species of the same country in the finely punctured and 

 wrinkled elytra and the short white hairs of the upper parts, as 

 well as the very distinct punctation of the thorax. Whether 

 C. pubescens Lefev. is identical with the present species can only 

 be ascertained by comparing the type, as a three-lined description 

 of insects which are so closely allied is of no use whatever, and an 

 abuse of science, which should be, in my opinion, totally ignored 

 with the rest of all such publications ; at any rate C. pubesceris is 

 described with the labrum obscure rufous, and the head, thorax, 

 and elytra densely and very finely punctured, which does not 

 apply to the species before me. 



COLASPOSOMA SUBAURETJH, sp. n. 



Obscure fulvous with aeneous gloss, pubescent, the apical joints 

 of the antennae black ; thorax finely and closely punctured, clothed 

 with long white hairs ; elytra with a deep fovea below the base, 

 closely punctured, the interstices transversely rugose throughout 

 and pubescent like the thorax. 



Length 5 niillim. 



Head closely punctured and clothed with rather long white 

 hairs ; labrum fulvous ; antennae extending slightly below the 

 middle of the elytra, fulvous, the terminal five joints black ; thorax 

 strongly transverse, three times broader than long, the sides 

 rounded, the fine punctation almost entirely covered by longish
