rugose, much less closely sculptured than the mesonotum, poste- 

 riorly with a raised line or carina on each side of the middle. 

 Wings clear hyaline, stigma yellow at base, dark fuscous on 

 apical part, costal and sub-costal nervures dark, as also the 

 transverse ones, the latter subinfuscate, and a rather narrow in- 

 fuscate band crosses the wing from about the middle of the stig- 

 ma. Abdomen glabrous and shining, the whole thorax having 

 short grey pubescence. Length 4 mm. 



Male black, the two basal joints of the antennae, the front 

 and middle legs except the coxae, yellowish brown or testaceous. 

 Hind tibiae pale on basal half, the tarsi still paler. Antennae 

 attenuated towards the apex, the third joint about one and a half 

 times the length of the fourth, the joints (except as previously 

 noted ) blackish, but tinged with yellow. Thorax sculptured like 

 the same parts in the female, the abdomen shining, very finely 

 indefinitely punctured, and impressed at the base. Wings h}'a- 

 line, costal, sub-costal and radial veins dark, stignija dark fuscous 

 except at base. Length 3 mm. 



HAB. Nogales, Arizona; bred from nymphs of Amphisccpa 

 bivittata. The number attached is 2426, clearly an error, for 2446, 

 under which number it is mentioned that two parasites were bred, 

 viz.: the present one and Hcspcrodrylnns aiiiphisccpac. The lar- 

 val sac, placed beneath the wing, is variegate, dark fuscous and 

 yellowish. 



Eukocbcleia Perk. 



This name is practically a duplication of Eukocbclca already 

 in use. I do not think it advisable to suggest any substitute at 

 present, because I have some doubt whether the g^juus is not 

 synonymous with Bocchns of Ashmead. As, however, the char- 

 acters of the mouth-parts, as given for Bocchns, are quite diflfer- 

 ent from those of my two species of Enkocbeleia, and further 

 the description of the tarsal generic characters does not agree, 

 while Dr. Ashmead's characterization is confirmed by Brues, I 

 must consider the two genera distinct. The fact that the follow- 

 ing species is fully winged will require some modification of the 

 original generic characters, as given by me. 



Eukoebclcia arizonica sp. nov. 



Generally like E. inirabilis, the Larsal structure similar, but the 

 winTs are well-developed and there is an infuscate transverse 

 fascia, narrowed below, placed beneath the radial vein.
