lO the middle in this genus. In one of the specimens the ligula is 

 plainly visible. It is long, narrow and undivided. The li'gula is 

 exactly similar in a specimen of the European T. angulata Er. 

 which agrees in other respects with Ganglbauer's description of that 

 species. It is possible, therefore, that the generic characterization 

 may be erroneous in this respect. Otherwise the species agrees well 

 with the description of Thiasopliila. 



Ptenidium simplicicoUe new species. 



Form short, robust, very convex. Color black, elytra pale apically from 

 diaphaneity, antennae and legs bright rufo-testaceous. Integuments very 

 strongly shining, completely impunctate and glabrous. Head nearly twice as 

 wide as long, eyes large, very convex, head three fifths the width of the thorax, 

 antennas reaching the base of the thorax. Thorax three fifths wider than long, 

 very slightly narrower than the elytra, apex a little narrower than the elytra, 

 apex a little narrower than the base, widest a little before the middle, sides 

 more arcuate and convergent anteriorly, oblique and nearly straight posteriorly, 

 disk very convex, entirely devoid of basal impressions. Scutellum with a 

 crenulate basal margin. Elytra evenly oval, one fourth longer than wide, 

 slightly more than twice as long as the thorax, as wide as the thorax at base, 

 humeri not exposed, widest at basal third, base with a finely beaded margin. 

 Legs somewhat robust. Length .9 mm., width .5 mm. 



Type 26 May. 



This species is distinct by the complete absence of thoracic fovese. 

 moderately transverse thorax, short elytra and the entirely glabrous 

 and impunctate integuments. 



Atomaria parviceps new species. 



Form very elongate, subparallel, convex, shining. Color uniform, rather 

 pale ferruginous. Head, thorax and elytra at base somewhat coarsely and 

 moderately closely punctured, punctuation becoming indistinct apically on the 

 elytra ; thoracic hypomera coarsely punctate anteriorly, metasternum, metepi- 

 sterna and elytral epipleurse coarsely and somewhat closely punctured, pubes- 

 cence moderately coarse and dense, inclined. Head rather small, not more 

 than three fifths the width of the thorax, antennae scarcely surpassing the base 

 of the thorax, first joint short and stout, scarcely as long as the next two, four, 

 six and eight small, globular, five slightly elongate, dub strong, nine and ten 

 distinctly transverse. Thorax one third wider than long, about five sixths the 

 width of the elytra, widest at basal one fourth, strongly narrowed and arcuate 

 to base, gradually and feebly arcuately but distinctly more narrowed apically, 

 apex distinctly narrower than the base, base narrowly impressed along the 

 margin. Elytra at the humeri very slightly wider than the thorax, three
