NEMATUS STEONGYLOGASTEB. 113 



Ab. Wings much shorter than body. 



The punctured vertex, whitish belly and costa with 

 the testaceous stigma, and pedal coloration will 

 readily distinguish this species. Sometimes the dorsal 

 segments of abdomen are white at their junction, and 

 more rarely there is a very thin brown ring surround- 

 ing the eyes. The $ appears to be quite unknown, 

 neither is anything known of the larva. 



A common species found in June, at the end of 

 July, and beginning of August. It is generally 

 distributed in Scotland from the border to Suther- 

 landshire. In England I have seen specimens from 

 Manchester (Chappell), and Glanville's Wootton, 

 Dorset. 



The only Continental localities I know of are 

 Sweden, Germany, and France.
