A NEW GENUS OF PSAMMOCHARID WASP FROM CHINA 



By P. P. Babiy 



When looking- through the undetermined Psammocharidae in the 

 United States National Museum I found several specimens of an ap- 

 parently undescribed form that drew my interest. I had already had 

 a specimen of this species under scrutiny in the American Museum of 

 Natural History in New York, but hacl hesitated to describe it from 

 only one sex. In Washington I found both sexes represented. This 

 is the first record of the subfamily Notocyphinae from the Asiatic 

 continent. The general appearance is that of Notocyp/ms, but the 

 labrum is not fully extended, a character that made me hesitate at 

 first to attribute it to the subfamily. 



Subfamily Notocyphinae 



SINOTOCYPHUS, new genus 



The labrum is broader than long and rounded below as in Minoto- 

 cyplius Banks, the other genus of the subfamily, described from the 

 Philippines. The malar space is exceedingly narrow ; the eyes are not 

 hairy. The antennae are slender. The head basis is more flattened 

 than in Notocyphus. The tips of the mid and hind tibiae show the 

 row of small subequal parallel spines — a character of the subfamily — 

 but a dense pubescence makes them less conspicuous. In the male 

 the abdomen is rather flattened. The male genitalia show a quite 

 different construction from those of Notocyphus. Unfortunately no 

 description of the male genitalia of Minotocyphus is available. The 

 small spines in pits so prominently mentioned for Minotocyphus are 

 present on the front coxae as well as the mid and hind legs. The
