DESCRIPTION OF A NEW CYNIPOID FROM TRINIDAD. 



BY S. A. ROHWER, Bureau of Entomology. 

 Diglyphosema anastrephae, new species. 



In Dalla Torre and Kieffer (1910 Das Tier. p. 245), this species 

 runs best to Diglyphosema flavipes Ashmead, but there are many 

 differences from that species. The wings are bare and the sculp- 

 ture of the scutellum is different. There is some doubt in my mind 

 as to the generic position, but in structure it is similar to Jiavipes 

 Ashmead. 



Female. Length, 2 mm. Length of antennae, 2 mm. Head polished 

 without sculpture; face with two impressed, slightly diverging, lines above 

 the cypeus; inner margins of the eyes evenly rounded so they are closest 

 together a short distance below the antennae; lateral ocelli placed on sides 

 of elevations so they look laterally; postocellar line subequal with ocellocular 

 line; seen from above the posterior orbits sharply converge and then become 

 parallel; seen from the side the posterior margin of the head is angulate 

 a short distance below the top of the eyes; antennae 13-jointed; scape and 

 pedicellum of subequal length; third joint longer than fourth or fifth and 

 about one-fourth shorter than the scape and pedicellum combined; joints 

 beyond the fourth strongly moniliform and striate, the apical joints wider 

 than the basal joints; apical joint one-fifth longer than the preceding; pro- 

 notum truncate anteriorly and carinate, lateral angles dentate and with 

 two dorsal teeth medianly; mesonotum polished; basin of scutellum rather 

 large nearly circular in outline; scutellum carinate laterally, the lateral 

 carinae extended so the apex is subdentate; dorsal surface of scutellum with 

 radiating rugae from the raised basin; posterior face of scutellum reticulate; 

 propodeum seen from behind hexagonal, shining with dense hairs medianly; 

 mesopleurae polished ; anterior margin of second abdominal segment trun- 

 cate, foveolate laterally ; wings bare; venation weak, apical abscissa of subcosta 

 present but not attaining margin of wing. Black; mandibles and legs (except 

 infuscate hind femora) rufous; wings hyaline. 



Male. Length 1.75 mm. Length of antennae 2 mm. Agrees well with 

 female; antennae 15-jointed, flagellum strongly moniliform and striate, the 

 median joints somewhat compressed. 



Type locality. Trinidad, B. W. I. Described from five fe- 

 males (one type) and one male reared in June and July, 1917, 

 from Anastrepha sp. by F. W. Urich and recorded under his 

 numbers F-I3 and F-i6. 



Type. Cat. No. 22029, U. S. Nat. Mus. 



If the base of the abdomen can be said to have a hair ring 

 (there is a hair band laterally but it is not complete) this species 

 will go to Lytosema Kieffer.
