CLISTOPYGA CANADENSIS Provancher. 



CUstopyga canadensis Provanchek, Nat. Can., vol. 12, 1880, p. 45. Type. — 

 Public Museum, Quebec. Female bearing yellow label 396. 



Discussion based on notes by S. A. Rohwer on type and female para- 

 type, and female in collection of Mr. Nathan Banks, together with one 

 female and two males in United States National Museum collection. 



Very distinct from any of the foregoing species by reason of its 

 almost entire lack of maculation. Face shining with distinct, sepa- 

 rate punctures medially, frons and orbits impunctate; ocelli small, 

 postocellar line slightly longer than ocell-ocular line ; scutellum and 

 postscutellum shining, practically impunctate; wings dusky, ner- 

 vellus broken slightly below middle; tergites with distinct, rather 

 close punctures, second slightly longer than third ; ovipositor rather 

 weakly upcurved. 



The female from the collection of Mr. Banks agrees with 

 Provancher's description and also with the above. It is 8.5 mm. 

 long. Those portions noted by Provancher as being white (that is, 

 palpi, front trochanters, and tegulae) are somewhat darker, and 

 there is no trace of the white annulus on the front tibia. The orbital 

 maculation is represented by very minute reddish spots at the top 

 of the eyes. The thorax is strongly compressed. The first tergite is 

 slightly elevated above with the carinae strong to summit. Two males 

 in the National Museum collection agree very well with the female. 

 The sculpture is slightly stronger. The lower cheeks are impressed 

 and carinate. In one of the males the orbital maculation is exactly 

 as in the female ; but in the other it is yellowish and more extensive, 

 being also represented by a short, narrow line at the side of the face. 



The type is from Cap Rouge, Quebec; the Banks specimen from 

 Middlesex Falls, Massachusetts; the National Museum female from 

 Nerepis, New Brunswick (A, G. Leavitt), and the two males from 

 Colorado and Oswego, New York.
