shorter than the third funicle joint, the first and second funicle joints 

 being cylindrical ovate; funicle joints 3 to 10 cylindrical, subequal, 

 about thrice longer than wide. Distal or club joint conic-ovate, 

 slightly shorter than the preceding joint, long. Pubescence sparse, 



From 1 specimen, f-inch objective, 1-inch optic, Bausch

Female. — Unknown, 



Described from a single male specimen found mounted on 

 a tag in the United States National Museum collections and 

 which bore the following labels : " 13-5 ", " 285 " and in 

 Ashmead's handwriting '' Gonatocerus atratus Ashm."; " Cara- 

 phractus harrijigtonii Ashm." Remounted in xylol-balsam. 



Habitat. — North America : (?) Canada.

 Washington, D. C, one male in xylol-balsam. 



10. Gonatocerus pyginsieiis species nova. 



Normal position. 



Female. — Length, 0.60 mm. ; small for the genus. 



Allied with the species grouped with anthonomi and ainericanus and 

 more especially with aureus and brufineus ; it may be distinguished at 

 once by means of the fact that the third funicle joint of the antennae 

 is somewhat lengthened, longer than the fourth and still longer than 

 either of the two proximal funicle joints. In coloration it is similar 

 to anthonomi but differs in having the base of the abdomen yellow. 

 Fore wings slightly fumated throughout. 



Fore wings with about from nineteen to twenty-three longitudinal 

 lines of discal cilia across the widest blade portion, the discal ciliation 

 fine and moderately dense, absent (with the exception of one or two 

 cilia) in the shape of a small triangular clear space just out from the 

 oblique limiting line of cilia which runs caudo-distad from the proxi- 

 mal end of the marginal vein (in the other, allied species, this area 

 has five or more cilia in it, in some nearly as densely ciliate as the 

 main portion of the blade). Marginal cilia of fore wings moderately 

 short, the longest not quite a fifth the greatest wing width. Otherwise 

 as in the allied species. 



Antennae normal ; scape long and slender, nearly as long as the 

 pedicel and first three funicle joints combined, slenderer at each end ; 

 pedicel obconic, distincth' larger than the first two funicle joints sepa- 

 rately and as long as any of the funicle joints. Funicle joints 1 and 2 

 subequal, rectangular, 2 slightly longer ; 3 subpyriform, enlarging 

 somewhat distad, a third longer than 2 and a fourth longer than 4; 

 the latter wider, cylindrical ovate ; funicle joints 5 and 6 subequal to
