NO. 2140. AMERICAN CHALCIDOID HYMENOPTERA—GIRAULT. 51 



ovate, about half the length of the funicle. Mandibles 10-dentate. 

 Marginal vein slightly longer than the submarginal, over thrice the 

 length of the stigmal, the latter much shorter than the postmarginal 

 which is not quite half the length of the marginal. Hind tibial spurs 

 double. Pronotum transverse-linear; scutellum simple. 



The apparent male is smaller with the flagellum brown, the legs 

 white except the caudal tibiae and middle and caudal femora (an- 

 other specimen bore legs colored as in the female) . The scape is com- 

 pressed and widened below, the second ring-joint very short, the third 

 club joint larger and with a terminal spine yet acute. The first three 

 funicle joints each bear a long branch from the same side at base. 

 Mandibles about 7-dentate. The two male forms differed considerably 

 in the details of the antennae and I do not like to connect either one 

 definitely as yet to this species. The mandibles were 5-dentate in 

 the form colored unlike the female. There is a white stripe across 

 the abdomen just out from base and the parapsidal furrows are com- 

 plete yet obscure. 



Described from two females and several males reared from larvae 

 of Desmia funeraZis^ Fairfax County, Virginia, June 6 (J. F. Strauss). 



Tijpes.—Csit No. 19629, U.S.N.M., two females on a tag; the head, 

 the hind tibiae, and the antennae on a slide. 



This species is somewhat similar to the female of Cratotechus larva- 

 rum Linnaeus (Thomson), which has the minute third joint of the 

 club tubular and the first ring-joint very short; but in larvarwm there 

 are only three funicle joints. There are in the United States National 

 Museum three specimens labeled as being this species, apparently in 

 Thomson's handwriting, two females labeled " Silvestri, Italy, Octo- 

 ber 7, 1902 " — and another which bears the specific label and is lo- 

 calized at Blankenburg. Thuringia. I doubt the identity of these 

 very much excepting the third). Two females in the same collec- 

 tion, labeled Cratotechus ungularis Thomson, had the antennae 10- 

 jointed, with three fimicle and club joints and the third club joint 

 large and distinct. In this species ungularis the hind tibial spurs 

 are double, an incidented observation here. The specimens were 

 labeled " Blankenburg, Thur. ? ." Cratotechus smerinthi Ashmead, 

 female, has antennae like ungularis^ that is as to segmentation. Type 

 examined. The club is somewhat enlarged, the first ring- joint much 

 shorter than the second ; the third club joint terminates in no distinct 

 spine, but its apex is nippled a little. The funicle is 3- jointed in 

 Trichogramma {Cratotechus) orgyiae (Fitch) which appears cor- 

 rectly placed now. 



The species is dedicated to Henrik Ibsen. 



In the genotype of Dlmmoclda the mandibles are large, broadly 

 truncate at apex, 10-dentate, the antennae are brownish, the pedicel
