100 Arthur M. Lea: 



Eodruin wide, feebly curved, shining ; with nuiuerousi small 

 punctures. Scape stout, inserted almost in exact middle of side 

 of rostrum, much shorter than funiole. Prothorax not much 

 wider than long-, sides strongly rounded, apex less than half the 

 Avidth of base ; with dense, lartre, round, concealed punctures. 

 Elytra, subcordate. base ahuost truncate, rather strongly in- 

 flated near base and then strongly diminishing in width to near 

 aipex ; with rows of large, rormd. concealed punctures ; inter- 

 stices rather strongly and almost equally convex. Abdomen 

 with large, partially concealed punctures. Length, 1| - 2J mm. 



The clothing is so dense that the derm is almost everywhere 

 concealed, and the elytra appear to be finely striated only. The 

 scales, however, are atbsent from all but the base of the rostrum. 

 The scales on the prothorax and abdomen are larger than else- 

 where. Ijut on the prothorax they are wider and more closely 

 applied to the derm than on the a.bdomen. Most of the scales 

 are of a pale uiuddy grey, but on each elytron there is usually 

 an irregular triangle of black scales, the base of which is on the 

 side, and the apex nearly touching the suttu-e about its middle ; 

 but the triangle is sometimes broken up into small and irregular 

 spots, or appears as an irregular fascia. There are usually some 

 snowy white scales on the elytra. The legs are usually feebly 

 annulated. On the elytra the darker setae usually form two 

 loose fascicles on the third interstice — one near the base, the 

 other median. I have a paiir taken //; cop., but cannot detect 

 any sexual differences, apart from a thickening of the male 

 femora. 



Nearer noctivagus than any other described species, but 

 smaller, with more variegated clothing, and which on the under 

 surface is sparser ; the scape shorter, stouter and more median, 

 and the mesosternal receptacle less raised and thinner.

A single specimen frcm ilio island evidently represents a 

 variety of this species ; it differs from the types in having Ihe 

 Vjody (l)ut not the apptMuhigcs) entirely black ; the clothing is 

 more variogated, and on the elytra the scales are distinctly 

 less ri'unded; this lartter character would probably have been
