100 ME. L. 0. HOWAED ON THE PAEASITIO HTMENOPTEEA 



d . Greatly resembles female ; pedicel of antennse not quite 

 so long in proportion to tte funicle-joints which follow; spine- 

 like process of metanotum represented by a slight elevation only ; 

 club of stigmal vein of fore wings more pronounced than in 

 female ; abdomen bluntly rounded at tip ; genital organs, when 

 exserted, fully two thirds the length of abdomen. 



The habitus of this genus is much like that of the preceding, 

 in spite of the marked differences in structural detail. The head 

 in all of the 18 specimens of both genera is thrown forward, the 

 labium brought close to the fore coxse, the occiput entirely ex- 

 posed, and the rather prominent and well-rounded pronotum 

 brought strongly into view. 



Eeotolepsia compacta, sp. n. 



5 . Length 1*8 millim. ; expanse 3 millim. Head, pronotum, 

 and mesonotum finely shagreened, mesonotum with a few sparse 

 round punctures, slightly glistening ; pleura smooth, except 

 mesepimeron and propleuron, which are faintly granulate ; meta- 

 scutellum very finely granulate ; abdomen nearly smooth, shining; 

 the long second abdominal tergite with two subparallel latero- 

 dorsal furrows extending from the cephalic nearly to the caudal 

 end of the segment ; between these furrows the cephalic end of 

 the tergite is delicately longitudinally striate, the striations arising 

 from the upturned cephalic border and fading away gradually 

 about the middle of the segment, the lateral ones being a little 

 longer than the central ones ; ventral surface of abdomen 

 delicately longitudinally striate, except at lateral border ; head, 

 mesonotum, and tip of abdomen with sparse whitish pubescence, 

 of which there is also quite a pronounced fringe on outer border 

 of hind coxse ; metanotal fimbria well marked. Greneral colour 

 dull black ; antennal scape and pedicel honey-yellow, the pedicel 

 shaded with brown above at base ; all legs, except coxse, uniform 

 honey-yellow, tijD of hind femora a little darker ; fore wings 

 slightly infuscated, the infuscation deeper in middle, veins dark 

 brown. 



c? . Somewhat smaller than female, which it resembles, how- 

 ever, in all other respects except usual sexual difi'erences and 

 those pointed out in generic diagnosis. 



Described from two female and two male specimens. St.
