MONOGKAPH OF THE NORTH AMERICAN PROCTOTRYPID^. 49 



My specimens were bred from a cynipiclous oak gall {Andricus folia- 

 tus Aslim.), and is probably parasitic on some coleopterous larva in- 

 habiting- the gall. 



Cephalonomia cyniplphila Ashm. 



Sclerochroa cyniijsiphila Ashni., loo. cit., ii, p. 75; Cress., Syn. Hym., p. 247. 



9 . — Length, 2™'". Head, thorax, and legs rnfo-testaceous, the collar 

 anteriorly and the metathorax waxy white, the abdomen black, pol- 

 ished. Antennie 12-joiuted, a little longer than the oblong head; 

 scape slightly longer than one-third the length of the head, bent, nar- 

 rowed at base; pedicel twice as long as thick; tlagellum very slightly 

 thickened at the middle, the flrst two joints very small, not longer 

 than thick, the following wider than long. 



Habitat. — Jacksonville, Fla. 



Type in Coll. Ashmead. 



Bred from a cyuipidous oak gall {Holcaspis omnivora Ashm.). It is 

 not necessarily parasitic on the cynipid, as other insects, dijjterous, 

 lepidopterous and coleopterous, were also reared from the gall. 



Cephalonomia hyalinipennis, sp. nov. 

 (PL III, Fig. 5, ^.) 



S 2 . — Length, 1 to 1.5™"'. Polished black ; scape and pedicel rufous ; 

 flagellum brown-black; legs piceous; wings hyaline; tegulae rufo- 

 piceous. 



The female in this species agrees in all respects with the male except 

 in having a much longer and broader abdomen, it being broadly ovate, 

 fully twice as Avide as the thorax, and in having a much longer head. 



Habitat. — Jacksonville, Fla. 



Type in Coll. Ashmead. 



The color and the female in having wings render the species easy of 

 ideutilication. 



The S was reared March, 1887, from the galls of Amphibolips cinerea 

 Ashm., while the 9 was bred April, 1887, from Holcaspis omnivora 

 Ashm. ; but notwithstanding they came from different galls, I believe 

 they are sexes of one and the same species. 



Mr. r. H. Chittenden has recently shown me several specimens of 

 what is evidently this same species, reared by him from the coleopteron 

 Hypothenemus eruditus, living in the dead twigs of the cultivated fig. 

 It diifers from my type in having black femora. 



Cephalonomia nubilipennis Ashm. 

 Holopedina nuMUpennis Ashm., loc. cit., iii, p. 97. 



S. — Length, l.S'""". Rufo-testaceous, smooth, impunctured; there 

 is a dusky blotch across the scutellum and on the disk of the abdo- 

 men ; collar and base of abdomen yellowish. The antennae are 12-jointed, 

 pale brown, 1 J times as long as the head ; the scape a little more than 

 one- third the length of the head, the pedicel stouter than the flagellar
