 on abdomen near base, the first narrowly interrupted at the meson. 

 Fore wings hyaline but centrally with a large round moonlike spot, 

 whose center is opposite the distal part of the marginal vein, the 

 stigmal \'ein not extending cfistad of its most ciistal circumferential 

 point; postmarginal vein distinctly shorter than the stigmal, the 

 venation yellow. Antenuce dull brownish yellow, the scape and ped- 

 icel metallic green (except bulb anci base of the former and apex and 

 ventral side of the latter). Funicle 1 two-thirds longer than wide,

Pcrihiuipus ccDuidoisis Crawforci. 

 This belongs in the first division of Crawford's (1914) table, anci 

 Is closely allied with siibcayiuatus ; but in the latter the lower face 

 (laterad of the clypeus) is finely cross-wrinkled, but in canadensis 

 It bears only a few punctures (and a line of smaller punctures up 

 the eye margin) ; the lower cheeks are similarly sculptured for the 

 respective species (that is, in subcarhiatus finely striate, and so on). 

 The carina referreci to in the table is the carinated edges of the 

 large scrobicular cavity (with the species bearing It, the face is 

 striate, otherwise smooth or mostly so). The carina is weak In 

 robertsoni, which resembles shnilis, but there Is more sculpture on 

 the head In the former; In robertsoni the venation Is pale, black in 

 sinii/is. The species subcarinalus and platxc/aster are very much 

 alike, but the latter has larger punctures on the clypeus and the 

 lateral margin is cross-wrinkled, while in the first species the clypeus 

 is practically smooth and with minute scattered punctures; more-
