64 Itlutilla pudioa sp. uov. 



Slender, pale ferruginous, cephalic punctures scattered, ocelli approximated, 

 mesotborax distantly punctured, grooves distinct, ruetathorax with long, smooth 

 basal space, pleurae largely reticulate, first abdominal segment small, nodose, 

 closely punctured, second almost impunctate, ruesosternnm with a pair of sharp, 

 stout teeth; legs fusco-testaceous ; wings yellowish, stigma black, third submar- 

 ginal open. 



Male. Pale ferruginous, apical segments fuscous, ocelli margined with black 

 interiorly. Head round, its punctures fine and scattered, ocelli rather small, the 

 front one distant from the others by about its length, hind ones closer to each 

 other than to the eyes; mandibles toothed near the tip, the basal production 

 large ; clypeus broadly concave ; antennae pale fuscous apically, scape minutely 

 punctured, sparsely short-hairy. Thorax elongate pyriform, slightly broader 

 than head, distantly punctured, median grooves of mesonotum entire, lateral 

 ones very shallow, abbreviated in front; scutellum rugoso-punctate ; metathorax 

 coarsely reticulate, basal area without median septum, extending two-thirds the 

 length of the segment; mesopleura? obsoletely punctured, mesosternum with a 

 pair of strong beak-like projections in front. Abdomen petiolate, first segment 

 small, longer than broad, nodose at tip, its punctures strong, confluent, ventral 

 keel dentate anteriorly ; second segment very sparsely and finely punctulate 

 above and below, remaining segments impunctate, pygidium convex. Femora 

 and tibia?, except base, fuscous, remainder of legs testaceous. Wings hyaline, with 

 faint yellow tinge, veins moderately strong, fuscous, stigma fuscous, third sub- 

 marginal cell open apically. Vestiture sparse over all, pale yellowish white. 



Length, 8.75 mm.

65. >l ulilla Pattersonse sp. nov. 



Robust; testaceous, including antennae and legs, process at base of mandibles 

 strong, head with fine distant punctures, rounded behind, mesonotum closely 

 punctate, the middle grooves distinct, mesosternum without armament, metatho- 

 rax coarsely reticulate, the bisected areas small, abdomen petiolate, the first seg- 

 ment closely punctured subnodose, remaining segments impunctate; vestiture 

 long, pale yellow, wings hyaline, veins and stigma testaceous, two suhmarginals. 



Male. Robust, rufotestaceous, clothed with rather long and moderately dense 

 whitish pile. Head round, finely punctured, ocelli large, the froi.t one distant 

 from the hind ones by less than its width, space between hind ones greater than 

 between them and the eyes; clypeus uniformly concave, truncate in front ; man- 

 dibles stout, basal process very large ; antenna? wholly testaceous, scape minutely 

 punctulate, its pubescence very short ; underside of head polished, impunctate. 

 Thorax elongate pyriform, broader than head, prothorax reticulate, mesonotum 

 closely and finely punctured in front, a little more sparsely behind, the grooves 

 distinct, middle ones entire, side ones abbreviated on the front third ; metathorax 

 rounded, coarsely reticulate on the disc, basal areas short and broad, in length 

 less than three reticulations; mesosternum irregularly punctured, medially 

 impressed, unarmed ; mesopleura? finely reticulate, the impressed smooth area
