TWO GENERA OF CHALCID-FLIES — GAHAN 363 



but not dense ; marginal vein about two and one-half times as long as 

 stigmal vein ; postmarginal about twice as long as stigmal. 



Type locality. — San Diego, Tex. 



Type.~\]. S. N. M. No. 56656. 



Remarks. — Described from 5 females (1 liolotype) and 1 male 

 labeled as having issued in May 1895 from Cyrtarachne sp., collected 

 at San Diego, Tex. Two of the female paratypes and the lone male 

 are badly broken and incomplete. 



Genus ENCYRTASPIS Ashraead 



Encyrtaspis Ashmead, Mem. Carnegie Mus., vol. 1, pp. 290, 492, 1904.— Gahan, 

 Proc. U. S. Nat. Mus., vol. 71, art. 4, p. 9, 1927. 



This genus is closely related to Arachnophaga Ashmead but may 

 be separated by the characters indicated in the discussion of that 

 genus. It is also close to Tineohius Ashmead but differs by having 

 a distinct tuft of long, stiff bristles on the scutellum, the ocelli in 

 an obtuse instead of an acute triangle, the frons not especially nar- 

 row, the vertex without a conspicuous patch of long, stiff bristles 

 behind the ocelli, and the postmarginal vein equal to or only slightly 

 longer than the stigmal vein. 



I published a full description of the genus together with a key to 

 the three then known species in the above cited reference. In the 

 present paper three additional species are added, two by transfer 

 from other genera and one a new species. 



The only species of w^hich the male has been described is semirufus 

 Gahan. 



KEY TO THE KNOWN SPECIES OF ENCYRTASPIS ASHMEAD 



FEMALES 



1. Exserted portion of ovipositor longer than head, thorax, and abdomen com- 



bined and with a broad, pale band n,ear apex; hypopygium extending a 

 little beyond apex of last dorsal segment of abdomen 



1. brasiliensis Ashmead 

 Exserted portion of ovipositor shorter and usually without a band ; hypopy- 

 gium not extending beyond apex of last dorsal segment of abdomen 2 



2. Frons above scrobicular depression finely and densely sculptured, 



subopaque 3 



Frons above scrobicular depression smooth and polished, with only sparse 

 and very minute hair punctures, or very weakly reticulated and always 

 shining 5 



3. Ovipositor sheath dark, with a yellowish band before its apex 



2. proximus Costa Lima 

 Ovipositor sheath unicolorous or at least without a pale band 4 



4. Antennal scape reaching level of anterior ocellus; posterior one-third of 



scapulae sharply carinate; hypopygium very nearly attaining apex of 

 abdomen 3. laticeps (Brues)
