Hab. Assam, Sudiya, Patkai Mts. 



Three specimens were collected by Mr. Dolierty, in which 

 no sexual difference is apparent. 



This little insect, one of the smallest Lamellicoru beetles 

 yet known, has a very great resemblance to the Japanese 

 Panelus parvulus, Waferh., figured by Mr. George Lewis in 

 the Ann. & Mag. Nat. Hist. 1895, (6) xvi. p. 375, 'ligs. 1 & 2, 

 the only species hitiierto described, although I have seen 

 several. It is a little smaller and relatively shorter, being 

 a trifle less produced behind. It is similarly sculptured, 

 but the elytra are a little more strongly striated and punc- 

 tured, and the prothorax has a smooth unpunctured strip at 

 the base, wdiich is separated by a distinct dividing-line from 

 the remaining strongly punctured surface. This smooth 

 area exists in P. parvulus^ but is not sharply defined. Tlie 

 most pronounced difference between the two forms, however, 

 is found in the lower surface. The metasternum, instead of 

 meeting the mesosternum in a broad lobe, is produced into 

 a very acute angle, apparently almost dividing the meso- 

 sternum into two. The sides of this process form quite 

 straight lines extending backwards to the posterior ends of 

 the middle coxse. These lines are finely raised, and under- 

 neath them can be traced another strongly pigmented line, 

 wliich probably represents the true meso-metasternal suture. 

 This line of dark pigment does not follow the direction of 

 the carinate lines in the posterior part, but branches off to 

 the middle of the intermediate coxae.
