27. C. denigratus, n. sp. 



Hah. Picliincha (12,000 feet). One examiik-. 



V. Altarensi simillimus sed differt antennis elongatis : gmciliur, niger 

 elytris ( (J ) alutaceis subopacis, antennis partibnsque oris fulvo-rufis : capite

 angustis : elytris longioribns, anguste oblongis, apice perparuni siniiatis, plica 

 basali fere recta, transversa, liumeris rotnndatis, puuctulato-striatis, inter-

Long. 9 niillim. ^. 



Very similar to C. Altarends in form, sculpture, and colour, l)Ut different 

 in the greater length of the antennae, and the elongation of the outt-r angle 

 of the fourth tarsal joint to the middle and hind legs, which assumes the pm- 

 portions of a lobe; so that the joint may be said to lie unilobulai'. The 

 insect is of more oblong form, but without the structural ditl'erences in 

 antennae and tarsi it would not be considt^ed as more than a local varietv of 

 ('. Altarensis. 



28. C. fiisipalim, n. sp. 



Hah. Cayambe (15,000 feet). One example. 



Sat gracilis, niger, antennis palpis pedilmsipic piceo-rufis : antennis lirevi- 

 bus sed articulis minus ovatis : capite ovatn, oculis parum ]iriiminentilius, 

 collo transversim modice depresso : palpis articulo ultimo late fusiformi : 

 thorace angusto ipiadrato ante basin profnnde sinuato, angulis jiosticis 

 exstantibus fere rectis : elytris ovatis subtiliter striatis iuterslitio tertin 

 tripunctato : tarsis articulo 4^" sat ])rofund{' emarginato, postcrinrum 

 angulis pi'oductis. 



Long. 6 1 millim. 



Apparently allied to V. ooi:>teroides (Chaud.), and possildy the sauie species, 

 but Chaudoir does not mention the thick fusiform terminal joint of the 

 maxillary and lal>ial palpi ; the swollen part of the joint being much wider 

 than the penultinaate. The antennas and legs are short and stout, the thoiax 

 is narrow, (puulrate Imt deejily sinuated before the Ijase, and the hind angles 

 salient and sharp at their apiices ; the liase is rugulose and thei'C is a slight 

 linear convexity between the fovea and the angle. The elytra are elongate- 

 ovate, the base narrow with well-marked curved basal plica, and the apex 

 rounded without sinuation. The metathoracic episterna are remarkably short, 

 and the fourth tarsal joint is much more deeply emarginated (nearly bilobed) 

 than in ('. juisttdosiix and allies.
