 Rkyssalus atriceps n. sp. 



Female.— Length, 2 mm ; ovipositor, |" im . Head smooth, polishedJ 

 black,; thorax, legs, and abdomen, pale ferruginous. Antenna- 22- 

 jointed, basal five or six joints yellowish, beyond dusky; the 3d joint

 the. middle lobe roughened, with a slight keel medially extending to 

 the base of the scutellnm; pleura delicately shagreened ; metathorax 

 rugose, areolated ; abdomen ovate, strigose, the three basal segments- 

 occupying most of the surface, the following very minute, together not 

 longer than half the length of the 3d. Wings hyaline, veins yellowish ; 

 the submedian cell is longer thau the median, the recurrent nervure 

 interstitial with the 1st transverse cubital, the latter oblique, the second
