to tlie apex ; the apical margiji well defined and crenulate, 

 extending laterally lialEway up the declivity. 



Length, 2'1 mm.; breadth, '9 mm. 



Bengal: Kaja Bhat Khawa (C. F. C. Beeson), ex Sal 



twig. 



Xylehorus hlcoloi\ Bland f., var. a. 



Head, legs, and prothorax yellow, the elytra dark reddish 

 brown. Front subconvex, sparsely punctured, with shoit, 

 obscure, median, longitudinal line over the epistoma ; the 

 eyes deeply emarginate. Prothorax longer than broad, the 

 sides subparallel, slightly broader in front, the basal angles 

 rounded, anteriorly transversely rugose as far as the trans- 

 verse central nodosity, posteriorly shining and smooth, with 

 a few minute punctures near the base especially. Scutellum 

 very minute. Elytra the same breadth as the base of the 

 prothorax and one-half longer ; lineate-punctate, interstices 

 flat, with uniseriate erect hairs, the sides subparallel, rounded 

 on the apical fifth ; viewed laterally, the apical declivity is 

 abrupt, the first and second interstices tuberculate and setose, 

 but not elevated. 



Length, 1*7 mm. ; breadth, '6 mm. 



India: Sunderbans Div. (C. F. C. Beeson). 



Probably onlj a local variety of the Japanese species 

 X. hicolor, Blandf., from which it differs in the absence of 

 the median longitudinal line on the prothorax, the shorter 

 and more abrupt elytral declivity, and t!ie flatter first and 

 second interstices on the declivity, each of which differences 

 appears to be constant.
