780 MR. M. JACOBY ON NEW [Dec. 16, 



gin much rounded, the latter broadly produced in the middle, all 

 the angles acute, the anterior ones slightly produced; surface remotely 

 but distinctly punctured. Elytra broadly oblong, rather convex 

 posteriorly, rather closely and regularly punctate-striate, more dis- 

 tinctly near the base than towards the apex, where the punctures 

 diminish greatly in size. Entirely dark violaceous blue ; underside 

 of the same colour, the legs and tarsi fulvous. Thighs unarmed. 



Distinguished from C. alcyonea, Erichs., by its greater size, the 

 colour of the antennas and the underside; from C. tibialis, Lefev., by 

 the uniform coloration of its legs. 



13. COLASPOIDES ATJSTRALIS, Sp. nOV. 



Oblong-ovate, broad. Bluish aeneous beneath, cupreous or viola- 

 ceous above ; base of antennae, labrum, and legs fulvous ; thorax 

 coarsely, elytra substriate-punctate. 



Length 3 lines. 



Hub. Australia, Queensland. 



Upper portion of the head finely, lower portion coarsely punctate ; 

 the apex of the clypeus, labrum, and palpi fulvo-testaceous ; antennae 

 filiform, the first six or seven joints fulvous, the rest black. Thorax 

 twice as broad as long, sides nearly straight at the base, rounded and 

 narrowed towards the apex, the posterior margin being in consequence 

 double as wide as the anterior one ; surface convex, not very closely 

 impressed with deep oblong punctures, which are more crowded at the 

 sides than on the disk. Scutellum very broad, smooth, metallic 

 green or cupreous. Elytra slightly depressed below the basilar space, 

 the depression not quite extending to the suture, rather deeply and 

 regularly punctate-striate, the interspaces smooth, but transversely 

 wrinkled below the base near the lateral margins ; the latter are also 

 impressed through their entire length with deep punctures ; the first 

 two rows of punctures unite before the middle and form one row of 

 closely approached punctures which runs parallel with the suture 

 to the apex, the latter obsoletely costate. Underside piceous with a 

 metallic bluish gloss, legs piceous or dark fulvous, thighs not armed 

 with a tooth. 



14. COLASPOIDES UNICOLOR, Sp. UOV. 



Ovate, very convex. Dark violaceous, base of antennas and palpi 

 testaceous ; head and thorax distantly, elytra closely puuctured. 



Length 3 lines. 



Hab. Chontales, Nicaragua. 



Head deeply but not closely punctured, with a longitudinal groove 

 in the middle of the vertex ; clypeus more closely punctured, labrum 

 metallic green ; basal joints of palpi fulvous, the apical joint piceous ; 

 antennae filiform, the third joint very slender and the longest, t\\i 

 fourth half the length, the three or four basal joints testaceous, the 

 rest black with a greenish gloss. Thorax very narrow, at least three 

 times as wide as long, sides evenly rounded, posterior margin much 

 produced towards the middle, anterior one much deflected towards 

 the sides, surface very distinctly punctured on the disk, more closely
