and deep; metanotum rather coarsely rugose, somewhat reticulate, metapleura 

 minutely sculptured, dull, appearing closely punctuate: wings almost as in cas- 

 taneicinctus, the transverse median nervure not so far beyond the basal nervure 

 as in that species. Abdomen polished ; the basal segment dullish, more minutely 

 sculptured than the metapleurte. Pubescent as in castaneicinctus and the other 

 species described here ; legs brownish testaceous, except the posterior coxii? which 

 are largely black, and apical half of posterior femora above, a band on the basal 

 tjiird of posterior tibia?, apical third of posterior tibiic and tarsi which are more 

 or less deep brown.

Microdus agathoides, n. sp. 



Female. — Length, 4 mm. Head polished; face with small, inconspicuous well- 

 separated punctures; clypeus more highly polished than the other portions of 

 the face; scape nearly as long as the first joint of the flagellum, pedicellum a 

 little wider than long. (Antenniv broken.) Thorax, except the metathorax, 

 polished, almost impunctuate and without sculpture of any kind; metathorax 

 with the pleura somewhat roughened and separated from the metanotum by a 

 rugulose linear area; metanotum with two longitudinal carninfe with a rough 

 surface between, the caricie a little wider apart near the base than at the apex; 

 wings fuscous, nervures and stigma blackish ; second submarginal cell sessile 

 but not broadly thus, almost perfectly triangular* transverse median nervure 

 meeting the median nervure a little beyond the basal nervure. Abdomen polished 

 and with a rather deep lateral impression at the suture between the first and 

 second segments; ovipositor nearly as long as the head, thorax and abdomen to- 

 gether. Thinly pubescent with white short hairs. Red ; antenna>, front, cox;e 

 excepting part of anterior pair, trochanters, base of four anterior femora; poste- 

 rior tibise, tarsi, and sheaths of the ovipositor black ; tibiiv and tarsi of four ante-

 Ascogaster mimeticus, n. sp. 



Superficially almost like Chelonus altitudinis. 



Female. — Length, 4 mm. Head dullish, rugulose; cheek nearly twice as 

 broad as the eye, somewhat striate; face and clypeus minutely punctured, the 

 face mostly rugulose, tending to reticulate; scape longer than the first joint of 

 the flagellum, pedicellum nearly as long as wide, antenna? thirty-nine jointed, or 

 with one or two joints more, some of the joints not clearly separated from the 

 adjoining joints. Thorax dullish reticulate; mesonotum to a great extent punc- 

 tured with small, closely arranged punctures; metathorax more coarsely reticu- 

 late than the pleura, with two blunt spines or projections between the lateral
