Colpur, uniformly light brown, first few abdominal segments slightly lighter 

 in colour, though blending with remainder of body; male appendage of same 

 colour as the head, intersegmental and body pigment carmine. Antennal 

 joint 1, concolorous with head; 2 brown shading to light brown at tip; 3 light 

 brown at base, brown in upper half with a circle of darker brown at tip; remaining 

 segments 4-9 brown. Legs brown concolprous with head with the exception 

 of upper haljf of fore-tibiae and fore-tarsi, which are light brown. Fore-wings 

 banded with two brown between three white areas. 



Females have been taken on a variety of plants of which may be 

 mentioned' Elymus condensatus, clover, cratcegus, cherry. Primus demissa and 

 Amelanchier at various times during May, June and July 1914-1918 at Victoria, 

 Lillooet, Agassiz, Vernon and Kelowna. The distribution of this species in the 

 Province of British Columbia must, therefore, be widespread, inasmuch as it 

 has been taken in localities varying from the humid to the arid. During the 

 summer of 1918 females of this species were observed to be in association with 

 the Onion Thrips {T. tahaci, upon which it is doubtljess predacious, on onion 

 foliage at Kelowna, B.C. Williams (3) records this species as predacious on 

 the pea thrips (Kakothrips pisivora West) in Europe, but also notes that it 

 feeds on pollen and plant juices (4).

This species apparently occurs commonly in British Columbia. It has 

 been taken on several occasions during May, June and July in the past three 

 years at points in the Okanagan Valley, and in the vicinity of Victoria on Van- 

 couver Island. It has been taken also on a variety of plants, among which 

 may be mentioned, Acer glabrum, Rihes viscosissimum, Sambucus racemosa, Hex 

 eiiropceiLS, apple, alder, Lithospermum pilosum, Amelanchier florida, and in 

 sweeping through general vegetation. Possibly the most notable record of its 

 presence in numbers was observed in Kelowna, B.C., during early July (1918) 

 in commercial onion plantations, where many specimens were seen associated 

 with and doubtless predacious upon the onion thrips (7". tahaci).. Mr. J. D. 

 Hood, to whom some British Columbia specimens were submitted, agreed that 

 my "/Idetermi nation was correct, though a remarkable addition to its known 

 distribution," (April, 1918). According to my information this species thus 

 far has only been recorded from Maryland, Virginia and New York State, 

 U. S. A. (6). 



Eleven specimens before me clearly agree with the account given by Hood 

 (5). The presence of slight transverse striations across the occiput constitutes
