1910] North American Paniscim 199 



not much broadened towards apex; the petiole is a Httle more than 

 one-third longer than the second segment, with the spiracles placed at two- 

 fifths its length, the second segment is about two and one-half times as 

 long as wide at apex. 



Described from one specimen, from San Esteban (Haines). 



This species resembles somewhat P. texanus, btit is larger, 

 differently colored, with a stump of a vein in the discoidal 

 nervure, and with the segments of the abdomen relatively 

 different. 



Paniscus melanostigma, Cam. 



Biologia Centrali Americana; Hymencptera, I, 1SS6, \^. 303. 



Rufo-testaceous, mesonoto nigro; capite flavo; flagello antennarum 

 fusco; alis hyalinis, stagmate nigro. Female. 



Long. 15 millim. 



Hab. Panama, Volcan de Chiriqui (Champion). 



Face closely punctured; metathorax closely transversely striated. 

 Areolet moderately large, straight, the recurrent nervure received a 

 little beyond the middle; there is no branch on the cubital nervure. 



Easily known from its allies by the black stigma and ner- 

 vures. The petiole is longer compared to the second segment 

 (the relative length of the two being as in P. geminatits) than in 

 P. tinctipennis . 



Paniscus nigripectus, Ashm. 



Proceedimgs of the United State? National Museum, XII, 1889, p. 42.t. 

 Female — Length 16 mm. This species is much more closely allied 

 to P. geminatus than is P. texanus, and structuralh^ it is almost iden- 

 tical, but the mesonotum, mesopectus, stigma, and veins are black; the 

 lateral ocelli touch the eye; the stump of the vein at the middle of the 

 cubitus is wanting, and the submedian cell is only one-third the length 

 of the transverse median nervure longer than the median cell; the 

 second abdominal segment is two-thirds the length of the petiole, the 

 spiracles situated at about one-third its length. 



Habitat. — Texas. 



Described from one specimen in Belfrage Collection. 



Paniscus ocellatus, Vk. 



Proceedings Entomological Society of Washington, Vol. XT, 1909, p. 211. 

 Female — 16 mm.; tegument pale castaneous to castaneous, orbital 

 margin yellowish, tips of mandibles and edge of ocelli more or less 

 blackish; wings faintly cloudy, transparent, stigma and costa pale, 

 translucent, other veins mostly brownish or almost black; anterior 

 ocellus elliptical, transverse, the shortest distance between the anterior 

 ocellus and the nearest point on the eye; antennae 59-jointed, cylindri- 

 cal, the joints well defined, the fifth to penultimate subequal and' longer 

 than wide at base, the apical joint rounded, subconicah a little longer
