PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 129 



than the second. Front and vertex shining, the former transversely 

 finely striated, keeled down the middle. Face and clypeus closely 

 punctured. Mandibles rufous. Mesonotum closely, irregularly reti- 

 culated , the sides closely strongly punctured. Scutellum more widely 

 and irregularly reticulated, its sides stoutly keeled. Metanotum 

 reticulated, more widely and distinctly on the basal than on the 

 apical slope ; the base bordered by a keel and with a small area, 

 longer than broad and of equal width in the centre. Propleurse 

 smooth, the apex with a stoutly striated border. Mesopleur® finely 

 rugose and irregularly obliquely striated. Metapleurse rugose and 

 irregularly reticulated. Abdomen smooth and shining ; the basal 

 two segments as long as the head and thorax united ; the first 

 shorter than the second and dilated at the apex. 



Transverse basal nervure interstitial ; disco-cubital roundly curved ; 

 third discoidal cellule at base more than half the width at the apex ; 

 transverse median nervure in hind wings unbroken. Hind tarsi 

 longer than tibiae, claws minute, the calcaria of moderate length ; 

 tarsi minutely spinose, slender. Antennae, slender, as long 

 as the head, thorax, and first segment of the abdomen. Scutellar 

 depression large, wide, deep. 



I have, unfortunately, not an example of Nototrachys for com- 

 parison, but the species I have described agrees fairly well with the 

 descriptions of that genus. 



Glatha, gen. nov. 



Hind wings with only two cellules, a large anterior, reaching to 

 shortly beyond the middle, and with the apex broadly rounded, and 

 a posterior, not reaching to the middle of the anterior and with its 

 apex straight and slightly oblique. Disco-cubital nervure intersti- 

 tial with the discoidal, rounded at the base, tlie third discoidal cellule 

 narrowed and pointed at the base ; second discoidal cellule one-third 

 wider at apex than at base. Hind tibiae as long as the trochanters 

 and femora united, curved and narrowed at the base ; the basal 

 joint of the trochanters about four times longer than the apical. 

 Mandibular teeth large, unequal. Hind metatarsus as long as the 

 other joints united. 



The transverse median nervure interstitial. Claws small, simple ; 

 apex of clypeus rounded. Eyes bare, converging below. Occiput 

 transverse, margined. 



This genus comes close to Agrypon, Foer., as defined by Ashmead 

 (Bull. U. S. Nat. Mus., XXIII., 89), which apparently is identical 

 with Atrometus, Schmied. (Zeits. fiir Hymen, u. Dipt. 1902, 361) non.
