NO. 2061. HYMENOPTERA FROM GUATEMALA— ROHWER. 515 



teriorly; ocelli in a low triangle; the postocellar line distinctly 

 shorter than the ocellocular line; lateral ocelli slightly below the 

 supraorbital line, latrad and caudad of each lateral ocellus is a circular 

 fovea; antennae long, filiform, the third joint slightly shorter than the 

 fourth; pronotum very slightly converging anteriorly, angulately 

 emarginate posteriorly; propodeum much elongate, sloping poste- 

 riorly, with a median raised line, the surface finely granular; legs very 

 feebly spined; claws with an erect inner tooth; the longer calcarium 

 of the posterior tibia less than half the length of the post-basitarsus; 

 abdomen cylindrical, first segment slightly narrowed anteriorly, sub- 

 equal in length with the second; third cubital cell slightly longer than 

 the second on the radius, the recurrent veins nearly in the middle of 

 the cells; transverse median of the fore wings its own length beyond 

 the basal vein; transverse median of the hind wings nearly intersti- 

 tial with the cubitus. Black; a rectangular yellow spot on the lower 

 inner orbits; wings strongly dusky with a faint purplish tinge ; vena- 

 tion dark brown basally, pale brown apically; abdomen and propo- 

 deum with fine appressed silvery pile. 



Guatemala City, Guatemala. Two males collected February, 1912, 

 by W. P. Cockerell. 



Type.— Cat. No. 15087 U.S.N.M. 



The broad cheeks, the flat thorax, especially the propodeum, give 

 this insect a curious appearance and it is likely that a new genus will 

 have to be made for it. 



ARACHNOPHROCTONUS COCKERELLAE, new species. 



This species may be separated from ferrugineus (Say) by the clear 

 wings and different relation of the ocelli. 



Male. — Length, 10.5 mm. Clypeus gently convexed, anterior mar- 

 gin truncate, the lateral margin roimded; imier margin of the eyes 

 slightly emarginate; the distance between them at vertex is less than 

 the distance between them at the clypeus; an impressed line from 

 anterior ocellus to between the bases of the antemiae (this line is much 

 stronger as it nears the antennae and is broader just in front of the 

 ocellus); the front between the antennae raised into a convexed 

 mound; postocellar line a trifle shorter than the ocellocular line; 

 antennae longer than the head and thorax, filiform, third and fourth 

 joints subequal in length; posterior margin of the pronotum broadly 

 arcuately emarginate; the dorsal aspect of the propodeum without 

 hair or pubescence; posterior aspect of the propodeum with irregu- 

 larly scattered black hair; transverse median of fore wings intersti- 

 tial with the basal vein; second cubital cell subequal in length with 

 the third on the cubitus; third cubital cell strongly narrowed above 

 so its length on the radius is less than the distance between the second 

 recurrent vein and the second transverse cubitus; transverse median
