Two siDecimens doubtfully referred to this; the elytra are 

 pitchy and margins and suture testaceous, they are scarcely 

 costate.

Sexual characters are visible here. Fabricius describes 

 the male, in which two segments are white, the apical 

 almost semicircular ; in the female the eyes are much 

 smaller and the subapical ventral plate deeply cut out. 



The species which I refer to this is about six lines in 

 length; the thorax is transverse and its hind angles pro- 

 duced and acute; the basal portion of the abdomen is 

 infuscate in the female. A species in my own collection 

 and in that of the Brussels Museum from Madras, Bombay 

 and Bengal, ditfers in being smaller (three and a half to 

 four lines); the thorax is not so wide and its angles are 

 nearly right ; while a third species, from Malacca and 

 Madras, is much smaller and has the elytra obliquely 

 truncate at the apex. 



I propose, then, provisionally to separate the various 

 species which are allied to, and rather closely resemble 

 vespertina, F., as follows : — 



1. Vespertina, Fab. Head black, prothorax channelled 

 in both sexes, elytra very closely punctured but not striate, 

 one or two nervures visible, anterior tibi^ dark, middle 

 pair infuscate in part, hind pair yellow. 



2. Substriata, n. sp. Head black, prothorax with a 

 fine raised medial line, elytra closely punctured, with the 

 punctures becoming arranged in rows, nervures not dis- 

 tinguished, but the interstices a little raised. Tibiae all 

 yellow.
