much developed.

 Mr. E. T. Cresson presented the following descriptions of new Hymen- 

 optera in the collection of the American Entomological Society : 



I.iris bruiineipes.-9.-Black, smooth and shining: mandiWes except 

 tip and the palpi, testaceous,- scape brown; mandibles w.th xnferu.r marg>n 

 e.itire : metathorax above finely coriaceous, opaque, sides finely str.ated the trun- 

 cated apex rugulose, with a small deep shining fovea on upper m.ddle; tegul^ 

 dull es aceous' wings subhyaline, a dark streak at tip of margmal cell nervures 

 and stigma piceous: n.arginal cell short and broad, the tips broadly trunca 

 first submarginal cell longer than the second and third together, rece^v^ng the 

 first recurrent nervure near the tip; second submarginal triangular, rece.v.ng the 

 second recurrent nervure slightly beyond the middle; third submarg.nal cell 

 narrow, rounded below and narrowed above towards the marginal; legs piceou., 

 tibiae and tarsi brownish-testaceous, tibi.-e spinose, the intermediate pair with two 

 spurs at tip : abdomen smooth and polished, impunetured. Length .2o inch. 

 ■\ar 9 -Middle of clvpeus, mandibles except tips, palpi, antennae, most of 

 prothorax, tegul«>, tubercl'es, and most of four anterior legs, testaceous; abdomen 



"^T-^iZltfl^f^'-- sides of fi.ce, clvpeus, mandibles except tips scape 

 beneath and tubercles, wliite ; flagellum brown above, testaceous beneath ; tegul^ 

 piceous ; metathorax with a deep depression at tip tibove ; wings pale fusco-hyalme, 

 the posterior pair paler, with a fuscous spot at tip. Length .23 inch 



Hah —Colorado ; Nevada ; (Morrison). This may not belong to the 

 o-enus in which it is placed, as the first submarginal cell receives a 

 recurrent nervure. The eyes in the % do not meet on the vertex, but 

 are as widely separated as in the 9 . 



Astata OCCidentalis.- % -Entirely black, clothed with glittering whitish 

 pubescence, quite dense on sides of the tace, cheeks and apex of metathorax; 

 front punctured, with a smooth shining depression before anterior ocellus ; meso- 

 thorax closely punctured and depressed anteriorly, sparsely punctured and shining 

 on the disk and posteriorly; scutellum sparsely punctured and shining the apex 

 denselv punctured: pleura at sides and beneath densely punctured and opaque;
