three pricklelike spines, one of which is apical, Prododeal areola 

 subrectangular, from two and one-half to three times as long as wide; 

 carinae bordered by well defined grooves; median carina complete to 

 lowest sixth or more. Lower portion of side of propodemn polished, 

 striate, with barely perceptible hairs on posterior half. Posterior 

 aspect of propodeiim with its carina linear, flattened on the top, and 

 complete. First tergite with preapical band of a single row of well 

 separated punctures at center, expanding laterally to coalesced 

 patches in which the anterior edge is abruptly impressed. First 

 sternite with lateral grooves extending, with frequent interruptions, 

 to near anterior apex; disk almost bare, highly polished, with 

 strongly light-reflecting medial convexity. Tergites 2 to 4 rather 

 finely punctate, with broad, nearly impunctate discal spaces : impunc- 

 tate apices medially many times as wide as the largest adjacent pri- 

 mary punctures. Pygidium finely and densely reticulo-punctate on 

 the basal half; impunctate emargination very broad; apical impunc- 

 tate portion not perceptibly wrinkled. Stylet sheath and palps 

 usually not extruding beyond tip of abdomen when in repose. 

 Length, 8 to 9 mm. 



Male. — Not known. 



Distrihution. — Assam, India. 



Type.— C?ii. No. 41805, U.S.N.M. Female, Cherrapunji, Assam, 

 India, April, 1926 (Clausen). 



Paratypes. — In the collections of the National Museum, the Brit- 

 ish Museum, the Illinois Natural History Survey, the Philadelphia 

 Academy of Natural Sciences, and the Japanese Beetle Laboratory: 

 One each of the same lot as the type. 



This species closely resembles the Zakow series of vernalis, but 

 differs in the following characters : It has no patch of minute punc- 

 tures dorso-medially on the vertex; the mesonotum lacks the median 

 impression and has finer punctures, the first tergite lacks the medial 

 patch of dense, minute punctures, the impunctate apices of the inter- 

 mediate tergites are wider, and the impunctate apex of the pygidium 

 is not wrinkled. The species is apparently closely related to pig- 

 Tneihtata also, and differs from it in having black legs, in the denser 

 punctation of the front, the deeper, more frequently interrupted 

 central groove of the side of the pronotum, and the finer punctures 

 of the metanotum and the intermediate tergites. The specimen in 

 the Japanese Beetle Laboratory has the lateral and medial grooves 

 of the scutum continuous.

Female. — Vertex with punctures of second-degree and third-
