 Elasuiostethus criiciatus (Say).

 Blasmostethus cooleyi (Van Duzee).

 Pcrillus hioculatiis var. clanda (Say).

Two of the varieties described by Van Duzee'' are represent- 

 ed : var. c, but with lateral pronotal margins red ; and var. d. 

 These varieties should be named by some student having 

 adequate material, whatever their origin and genetic nature. 

 Apateticus hractcatns (Fitch). 



Alb. — Edmonton, June 15, July 15, 1912 (J. A. M.). 



With nymphs (July and August), probably of this species. 

 Apateticus crocatus (Uhler). 



B. C— Saanich Dist., V. I., Aug. 29, Oct. 10, 1917 (W. D.) 



This species has a peculiar habitus, difficult to describe, and 

 the genital pieces differ in form from those of hracteatus. 

 The male genital segment in crocatus is narrower and its later- 

 al margins are more evenly curved, less sinuate or irregular. 

 In the female sternite 10 is rather distinctly transverse, with 

 its lateral margins less cut into by the projection of para- 

 sternite 9 on. each side than in hracteatus, where sternite 10 

 is nearly as long as broad and somewhat hour-glass shaped".
