10. — Colparihrum irifoveatiim, n. sp. 



Moderately elongate, widened posteriorly, sliining ; aeneo-piceous or 

 aeneo-castaneous, the femora testaceous or flavous at the base ; the head 

 and elytra set with very lung, scattered, erect, setiform hairs. Head smooth, 

 a little broader than the prothorax, considerably developed behind the eyes, 

 the transverse inter-ocular groove very deeply trifoveate, the eyes rather small, 

 distant; antennae moderately long, joint 11 not much longer than 10 in $ 

 [wanting in c5']- Prothorax oblongo-subcordate, about as long as broad, 

 smooth, transversely compressed on each side at about the middle, the basal 

 groove very deep. Elytra moderately long, at the base twice as wide as the 

 prothorax, compressed below the humeri and gradually widened thence to 

 the middle, acuminate at the apex, the transverse post-basal depression deep ; 

 rather tinely striato-punctate on the disc, the punctures not very closely placed, 

 becoming much coarser and deeper towards the sides, and almost obsolete on 

 the apical declivity ; the interstices flat throughout, 1, 3, 5, 7, and 9 each with 

 a scattered series of conspicuous setigerous punctures. Femora strongly 

 clavate ; posterior tibiae curved in J . 



Length 6^, breadth 2|-2i mm. 



Kab. : Colombia {Mus. Brit.). 



Two specimens, assumed to be S and $ , the latter acquired in 

 1847. A rather short form, with comparatively narrow head and pro- 

 thorax, a deeply trifoveate inter-ocular depression, and broad, acuminate, 

 feebly seriato-punctate elytra, without trace of striae, and the alternate 

 interstices each bearing a scattered row of setigerous impressions. The 

 only described species of the genus from Colombia is C. gerstdclceri Kirsch, 

 a testaceous, nigro-fasciate insect, 12 mm. in length. 



11. — Colparthriim laevicanda, n. sp. 



cJ. Moderately elongate, widened posteriorly, very shining; fusco- 

 castaneous, the eyes ayd antennae darker; the elytra with a few erect 

 setiform hairs. Head about as long as broad, well-developed behind the 

 eyes, smooth, the transverse inter-ocular depression foveate on each side, 

 the eyes moderately large and separated by less than the width of one of 

 them; [antennae broken]. Prothorax elongate-cordate, dilated at the base, 

 considerably longer than broad, as wide as the head, smooth, the transverse 

 basal groove rather shallow. Elytra moderately long, at one-half from the 

 base more than twice as broad as the prothorax, compressed below the pro- 

 minent humeri, widened to the middle, and somewhat acumina-te at the apex; 

 finely, shallowl}' striato-punctate, the punctures becoming coarser at the sides 

 and obsolete towards the tip, the interstices broad, flat, 3, 5, 7, and 9 each 

 with several widely separated setigerous impressions. Femora clavate ; 

 posterior tibiae curved.
