30 AMERICAN HYMENOPTERA. 



nervures fuscous to black, sometimes varied with flavous ; discocubital 

 vein obtuse-angularly bent or broken, but without trace of an ap- 

 pendix ; nervulus antef ureal to interstitial, nervellus broken at or below 

 the middle ; first recurrent vein not over half the length of the second ; 

 legs of general color, claws pectinate. 



Abdomen about two and one-half times as long as the thorax, com- 

 pressed, smooth, and shining, clothed with fine short pubescence, the 

 first segment one-third longer than the second. 



In describing this species I have compared the types and 

 three 9 specimens with the original description. 



Types.— 6" 9 . No. 6138, U. S. National Museum. 



This is one of the smaller, rarer, species, which is not well 

 known. It may be readily recognized by its small size, 

 wings tinged with fuscous, and the discocubital nervures not 

 appendiculate. A larger series may show that the discocu- 

 bital vein is, as in bifoveolatus, sometimes appendiculate. 



Distribution. — Lower California, New Mexico. 



This species appears to range through southwestern United 

 States and northern Mexico. The types were taken at El 

 Taste and El Chinche, Lower California, Mexico, and two 9 

 specimens in the National Museum come from San Jose del 

 Cabo, Lower California, while a specimen in the American 

 Entomological Society Museum, which seems to belong here, 

 comes from New Mexico. Nothing is known of the life 

 history, habits or hosts.
