Oct.,1917 Bulletin of the Brooklyn Entomological Society 87 



segment 2 occupying a fourth of the surface, its caudal margin convex, 

 entire. Antennse inserted somewhat above the ends of the eyes, the scape 

 slender, reaching to the top of the vertex; pedicel twice longer than wide 

 at apex, much longer than any funicle joint; ring-joints unequal; funicle 

 I (a ring-joint?) quadrate, narrower than the following joint's; 2 and 

 3 subquadrate, wider than i, 6 twice wider than long. Stigmal vein long 

 and slender, slightly shorter than the marginal which is slightly shorter 

 than the postmarginal. 



The male is similar but funicle i is wider than long, still more like a 

 ring-joint, the pedicel shorter; also the cephalic tibiae are reddish yellow. 



From several pairs reared from Coleophora malivorella. Walnut Creek, 

 Cal., June 7, 1916 (W. M. Davidson). Types: Cat. No. 20,971, U. S. Nat. 

 Mus., one male, three females on tags, a female head and hind legs on a 

 slide. Also at San Jose (Moulton, 1909), Los Angeles (Coqulllett), and 

 Mountain View (Ehrhorn), Cal. 



Gonatocerus titillatus n. sp. — Female : Like maga Girault but the fore- 

 wings are subhyaline, nearly the basal half of the abdomen is yellow 

 (above this yellow with three cross stripes, the first well out from base), 

 the legs are yellow except coxae and femora (the latter except at apex), 

 the funicle is of uniform width, the club slender, funicle i over twice 

 longer than wide, 2 and 3 subequal, longest', over thrice longer than wide, 

 7 nearly as long as either, the others subequal, twice longer than wide and 

 subequal to the pedicel. Longest marginal fringes of fore-wing somewhat 

 less than half the width of those wings. Thorax scaly, the propodeum 

 subglabrous, non-carinate. Ovipositor extruded for a sixth the length of 

 the conical abdomen which is distinctly longer than the thorax. 



One female. Salt Lake, Utah, from a window (C. N. Ainslie). Type: 

 Cat. No. 20,972, U. S. Nat. Mus., the female on a slide. 



Ormyrus unfasciatipennis n. sp. — Female : Length 2.70 mm. Like un- 

 maculatipennis but the, fuscous area on the fore-wing is continued across 

 the wing and widens caudad ; the legs are entirely metallic except the tarsi 

 and the knees and tips of tibiae more or less broadly, cephalic legs washed 

 with metallic only; the antennae are wholly metallic except the scape more 

 or less at each end and ventrad ; and the punctures on the abdomen are in 

 triple rows, the first line in each row at first incomplete. 



Described from one female in the U. S. Nat. Mus. from Los Angeles 

 Co., Cal. (Coquillett). Types: Cat. No. 20,975, U. S. Nat. Mus., the above 

 female minutien mounted. 



Ormyrus thymus n. sp. — Female : Similar to unmaculatipennis except 

 that the antennae and legs are entirely metallic green except the reddish 

 brown tarsi, the spot on the fore-wing is longer than wide, obliquely trun- 

 cate distad and widens distad, extending a little beyond the middle, the 

 median carina on the abdomen is obscure and the lines of punctures single 

 except in places.
