GASTERUPTION. 



GASTERUPTION (FCENUS) PATTERSONS, sp. nov. 



Female. Length, iimm., ovipositor 10 mm. Body ferruginous. Head 

 black. Dorsum of thorax ; dorsal line on first abdominal segment, extend- 

 ing nearly to tip of segment ; dorsal spots on second and third segments, 

 somewhat indistinct on third ; then a dorsal line which widens out, so that 

 it covers the last segment almost completely ; piceous. Ovipositor shields 

 very dark fuscous. Legs ferruginous, hind tibiae slightly darker outwardly 

 and toward apex, and banded with white near base. Clypeus and mandi- 

 bles ferruginous, the latter black at extreme tip. Palpi rufous, last joint 

 black. Antennae about as long as head and thorax, fuscous ; scape 

 rufous ; flagellum black at base and lighter below except on apical joint. 

 Wings hyaline, nervures and stigma fuscous. Head, thorax, and posterior 

 covae silvery pubescent. Clypeus quadridentate, fringed with golden hairs. 

 Front punctate above antennas, and very finely and somewhat obsoletely, 

 transversely aciculate. Prothorax rather deeply and finely punctured. 

 Pleurae rugose ; dorsum and metathorax transversely rugose aciculate. 

 Abdomen impunctured, smooth, not very shining ; strongly compressed at 

 base, widest at third segment which is one- half as wide as high. Ovipositor 

 longer than abdomen, alutaceous. 



Described from a female specimen, collected by Miss Rose 

 Patterson, August n, 1898, at San Jose, California. 



This species may be readily recognized by the entirely ferrug- 

 inous pleurae, legs, and antennal scape and by the very slight 

 amount of black upon the abdomen. It is the only species re- 

 corded from California. 



Mr. Ashmead 2 has pointed out the synonymy of Fcenus Fabr., 

 and Gasteruption, which was described two years previously, viz., 



in 1796, by Latreille.

 so far known may be recognized by the following artificial key :
