TRICLIONA. 469 



fulvous, about half as broad again as long, subcylindrical, the sides 

 very slightly rounded, the disc sparingly punctured in the middle, 

 the sides nearly im punctate, marked with two narrow longitudinal 

 short black stripes from the middle of the anterior margin not 

 extending to the base ; the stripes have a slight outward direction 

 and vary in width and length, being sometimes reduced to two 

 small spots. Elytra subcylindrical, scarcely depressed below the 

 base, strongly punctate-striate anteriorly, very finely so towards 

 the middle, the apex entirely impunctate ; the sutural and lateral 

 margins, an elongate spot at the middle of the basal margin 

 extending to one-fourth the length of the elytra and a roundish 

 spot immediately behind the middle, placed in a line with the 

 first, black. Underside fulvous, the breast black ; femora with a 

 small tooth; the posterior four tibiae strongly emarginate at the 

 apex ; claws bifid. Anterior margin of the thoracic episternum 

 strongly convex. 



Var, a. Beneath entirely fulvous. 



Var. b. Thorax with two small spots : elytra with basal 

 spots only. 



Var. c. Entirely fulvous without spots. 



Var. d. Thorax and elytra black or only the former fulvous. 



Length 2-2 mm. 



Hab. Southern Bombay : Kanara ; Sumatra. 



This species greatly resembles P. binotata, Jac., from Mexico, 

 and cannot easily be distinguished from that species, but the 

 posterior spot on the elytra in the present insect is placed lower 

 down than in the Mexican form ; the general size of the latter 

 is also larger. Mogdiliani also obtained this species in Sumatra. 

 It is subject to a great deal of variation ; the black colour of the 

 lateral margin of the elytra is often widened at the middle, the 

 antennae and the entire upper surface are sometimes entirely 

 fulvous. Again, pale fiavous specimens without spots occur, as 

 well as those in which the entire upper surface is black or the 

 black colour may be confined to the elytra. It is one of the most 

 variable insects imaginable in regard to colour.

 thicker. Thorax transverse, sides rounded, anterior and posterior
