Phyllopidea picta var. hirta Van Duzee.* This form was previously 

 recorded under the genus Bolteria. Knight has shown" that this assign- 

 ment is incorrect, and he has kindly confirmed the determination of 

 the British Columbia material. 



Family GERRIDAE 



Gerris marginatus Say. Beaver Lake, Saanich Dist., 9-VIII-'19 

 (W.D.). A brachypterous male having the hemielytra extending to the 

 middle of the fourth abdominal segment. 



Gerris buenoi Kirkaldy. Beaver Lake, Saanich Dist., 9-\'III-'19 

 (W.D.). A brachypterous female having the hemielytra extending to 

 the level of the apex of the middle coxae. Short-winged forms are rare 

 in this species but are of wide spread occurrence, as I have found them 

 on Long Island, N.Y., and Hussey^" has reported apterous individuals 

 from Michigan. Family SALDIDAE 



Saldula interstitialis Say. Duncan, 17-IX-'19 (W.D.) ; Saanich 

 Dist, 17-VI-'19 (W.D.); Shawnigan, 2-VIII-'19 (W.D.). These speci- 

 mens from British Columbia cannot be distinguished from those occur- 

 ring abundantly in the Eastern States, which at present are considered 

 to represent the interstitialis of Say. In working out the Saldids 

 reported on in this paper I have been favoured with the advice of my 

 friend, Mr. J. R. de la Torre-Bueno, -who is engaged upon a monograph 

 of the North American species. 



Saldula comata sp. nov. 



Black, shining, the hemielytra conspicuously marked with dull 

 yellow as follows : a series of narrow spots within the costal margin, 

 variably developed ; a large ocellate spot occupying most of the middle 

 areole before the middle ; between this and the costal rovv, two or three 

 large irregular blotches, and behind it two near the membranal suture, 

 the outer long and narrow, the inner very small ; a small oval spot at 

 apex of clavus. Membrance translucent brown with one or two dark 

 spots in each areole. Head black, with small yellow spots between 

 ocelli and eyes and in front of the latter; tylus reddish yellow with a 

 black spot at base ; antennae black with a reddish yellow streak on the 

 inner side of the first segment. Rostrum and ventral surface black. 

 Legs largely dark reddish yellow, the feinora with a black longitudinal 

 stripe of variable width and black dots, the anterior and middle tibiae 

 with a black stripe on the outer side, which is variably developed and 

 does not reach the apex ; second tarsal segment yellow, the third black 

 or brown. 



Entire dorsal surface, excepting membrane, with legs and antennae,
