ART. 4 NEW PARASITIC HYMENOPTERA GAHAN 9 



all tergites uniformly finely shagreened and dull, the fourth to sixth 

 much more conspicuouslj'" hairy than the preceding, the sixth entirely 

 without the coarse punctures present in flavijjes Ashmead. Head, 

 antennal fiagellum, thorax, abdomen, and all coxae black; scape, 

 pedicel, tegulae and all legs, except their coxae, pale testaceous; 

 wings hyaline, venation dark brown; cilia of wings brownish, hairs 

 of body silvery white. 



Female unknown. 



Type locality .—Sixoila, Valley, Limon, Costa Rica. 



Type.— Cat. No. 29441, U.S.N.M. 



Described from seven male specimens (one type) sent in for deter- 

 mination by F. R. Swift with the statement that they were parasitic

Family EUPELMIDAE 



Genus ENCYRTASPIS Ashmead 



Encyrtaspis Ashmead, Mem. Carnegie Mus. vol. 1, 1900, pp. 290, 492. 



The description of this genus by Ashmead is to some extent in- 

 accurate and excludes the new species described below which is 

 certainly closely related to the genotype. A redescription seems 

 desirable. 



Female. — Head viewed from above transverse, as wide as the thorax 

 or nearly so; occiput moderately concave and immargined; posterior 

 orbits rather narrow ; ocelli not far from the eye-margin, arranged in 

 a slightly obtuse triangle; viewed from in front the head is as long 

 as broad or longer than broad; antennae inserted distinctly below 

 the ventral margins of eyes, broadly separated at base; scrobes 

 consisting of a rounded shallow depression which is poorly defined; 

 eyes rather large, faintly hairy, more or less convergent above; 

 antennae 13-jointed; scape reaching to front ocellus, slightly curved; 

 fiagellum gradually increasing in thickness from pedicel to club; club 

 obliquely truncate; mesoscutum trilobed, more or less depressed in 

 the middle posteriorly, the lateral lobes either carinate or noncarinate 

 posteriorly; axillae distinctly separated; scutellum convex, rounded 

 behind, with a prominent median longitudinal crest of stiff black 

 bristles; marginal and submarginal veins subequal, stigmal moder- 

 ately long and subequal to the postmarginal or a little longer; fore wing 

 with a broad transverse band embracing most of the submarginal 

 vein devoid of cilia, a small area at extreme base and the whole disk 

 of wing beyond the apex of submarginal densely ciliated and with a 

 dark fuscous cloud covering the whole area behind the marginal and 

 postmarginal vein; front femora slightly swollen; middle tarsi swollen 

 and distinctly spined beneath; hind femora not swollen, their tibiae
