of Olirysohothris femorata Fabricius and tliis seems to be a correct 

 association. 



LABENA APICALIS Cresson. 



Labena apicalis Cresson, Proc. Ent. Soc. Phila., vol. 3, 1864, p. 402. 



Type. — Cat. No. 1532, Acad. Nat. Sci. Philadelphia, a single male 

 without a head. 



This species is very closely allied to grallator Say and it is not un- 

 likely that when more material is available it v/ill be found impos- 

 sible to retain this name. The characters given in the above key 

 will, however, distinguish the specimens examined. The species is 

 smaller and has paler wings than grallator, but has much the same 

 range and is subject to about the same variation in the carination 

 of the propodeum. 



Distribution. — The type locality is Delaware, but besides the type, 

 specimens have been examined from the following localities: Texas 

 (Belfrage) ; Dallas (F. C. Bishopp) , Paris (C. T. Brues) and Victoria 

 (J. D. Mitchell), Texas; Lawrence, Kansas (Hugo Kahl); and Preg- 

 nall, South Carolina (Fiske). 



Host. — Riley and Howard have recorded this species as a parasite 

 of Olirysohothris femorata Fabricius, but the specimen which formed 

 the basis of this record is here referred to as confusa var. minor Roh- 

 wer. A male and female were reared from the galleries of Lixus 

 scrohicoUis Boheman in Ambrosia trijida by J. D. Mitchell (Hunter 

 No. 219). One male reared by J. D. Mitchell from stems of Verhe- 

 sina virginica infested by Lixus scrohicoUis Boheman (Hunter No. 

 1397). 



LABENA CONFUSA, new species. 



This species is very similar to grallator (Say) but can be separated 

 from that species by the characters used in the above key. 



Female. — Length 16 mm., length of ovipositor 12 mm. Distance 

 between the eyes and the clypeus practically the same as at the ver- 

 tex; face transversely roughened, without distinct carinae, tubercles 

 or folds; vertex and posterior orbits smooth, polished; ocelli in a 

 low triangle; postocellar line much longer than the ocellocular line; 

 postocellar furrow distinct; interocellar area convex and deeply 

 parted by a median furrow; thorax with close, distinct punctures 

 which are more widely separated on the propodeum and dorsal part 

 of mesepisternum; propodeal carinae strong; basal area about 

 twice as wide as long; areola longer than wide, receiving costulae 

 before the middle; anterior margin of propodeal spiracle strongly 

 curved; abdomen subpetiolate, shining, without sculpture; chiti- 

 nized basal part of first sternite terminating a short distance before 

 a line drawn tangent to the anterior margin of the spiracle; ovi^ 

 positor subequal in length with abdomen. Ferruginous with yellow- 

 ish and blackish marks; orbits, spot on tegidae, line below, hind
