primary punctures large, shallow, but clearly outlined, of first-degree 

 density, with tendency to grouping in rows ; secondary punctures well 

 differentiated and somewhat more numerous than the primaries, 

 except in upper anterior region. Scutellum with its minutely punc- 

 tate apex wider at places than diameter of the lowest primary punc- 

 tures. Metanotum densely bipunctate, the primary punctures of 

 third-degree density and much smaller than the largest on the scutel- 

 lum. Wings with the usual hyaline lines scarcely visible; radial 

 cell greatl)'^ exceeding second cubital cell in apical extension. Pro- 

 podeum with areola one and one-fourth times as long as wide, with 

 concave, converging sides; longitudinal carinae crenulate; median 

 carina complete ; side with its lower portion finely striate and without 

 hairs; posterior aspect with median carina on lowest fourth. First 

 tergite with preapical band not abruptly impressed, and consisting 

 at center of a single row of punctures, expanding at sides, where it 

 is also farther removed from apex. First sternite polished on disk, 

 with numerous clearly outlined round punctures, and with a medial 

 keel on anterior half, lateral grooves absent. Tergites 3 to 5 with 

 fine, deep, clearly outlined punctures which become sparse apically; 

 impunctate margin subobsolete, at most twice as wide as diameter 

 of largest adjacent primary punctures; marginal linear groove usu- 

 ally complete across dorsum; lateral denticle of fifth sternite present 

 as a longitudinal ridge over a large orifice with an upright, angular 

 tooth in the floor of the orifice. Length, 8 to 12 millimeters. 



Distrihution. — Fukien and Chekiang, China. 



Ti/pe.—C^t. No. 41782, U.S.N.M. Type, male Kuliang, China, 

 1926 (Jen). 



Paratyfes. — All males. Retained in the collection of the Japanese 

 Beetle Laboratory: One, Hangchow, China, July, 1925 ( Jaynes) ; 

 1, Kuliang, China, 1926 (Jen). Deposited with the U. S. National 

 Museum: Twenty-four, Kuliang, China, 1925 (Jen). Deposited in 

 the collections of the British Museum, the Illinois Natural History 

 Survey, and the Philadelphia Academy of Natural Sciences: One 

 each of the same lot as the last. 



The single specimen from Hangchow differs slightly from the type 

 in being larger, in having the third antennal joint distinctly longer 

 than its greatest Avidth, and in having the marginal grooves complete 

 across the dorsum in only the third tergite. The large orifice on the 

 fifth sternite, with the projecting tooth on its floor, is distinctly dif- 

 ferent from any other species examined. It may possibly be the male 

 of one of the species of which females only are discussed in this 

 paper, possibly of steo-nocarinata collected at the same locality. The 

 associations are vague, however, and can not be accepted until sup- 

 ported by further data.
