188 AMERICAN HYMENOPTERA. 



Type. — University of Kansas. 



Type locality. — Douglas Co., Kansas, 900 ft. 



One % , collected in July (U. of K., lot 61). 



Mulilla (Photomorphiis ?) crepiiscula n. sp. 



Intermediate between Photoinorphus and Odoutophotopsis. Tlie 

 anterior ocellus being distinctly larger than a posterior ocellus. 



%. — 5 mm. — Head. — Typical. 



Thorax.— The anterior lateral margin of the prothorax bounded by a faint 

 ridge ; punctures of pronotum shallow, distinct and rather sparse, the punctures 

 1-3 or more puncture widths apart; propleura with a few shallow rather indis- 

 tinct punctures; mesonotum about as sparsely punctured as the pronotum, but 

 the punctures somewhat larger and more distinct, parapsidal grooves absent ; scu- 

 tellum and postscutellum rather rugose hut shining; mesosternum anteriorly on 

 each side of the median furrow developed into a transverse creuulate ridge, 

 which, at the furrow, is rather acute angled and directed downwards and back- 

 wards ; metathorax, excepting metanotum and pleura, distinctly reticulated, the 

 space about as large as a lateral ocellus; metanotum with a longitudinal smooth 

 space about twice as long as broad at the base and one and a half times as broad 

 at apex as at base and divided into two equal parts by a longitudinal distinct 

 raised line or septum; metapleura smooth and shining; first submarginal cell 

 about as large in area as the second submarginal cell, but somewhat longer than 

 the latter cell, cubitus forming an obtuse angle at the insertion of the first trans- 

 verse cubitus and forming a more obtuse angle at the junction of the recurrent 

 nervure with it, first transverse cubitus forniing an acute angle with the radius 

 to which it joins, so that the first abcissa of the radius is only about as long as 

 the third antennal joint, the second abcissa of the cubitus about twice as long as 

 the first abcissa. 



Abdomen. — Petiole typical, with sparse shallow punctures from six to eight, and 

 in some places more puncture widths separating the punctures, second segment 

 polished and punctured, the punctures separated as on the petiole, the felt line 

 or impression running nearly parallel with and just within the lateral margin of 

 the second dorsal segment extending nearly all the way from the anterior to the 

 posterior margin of this surface, the corresponding line on the second ventral 

 segment about one-third the length of this latter segment ; the segments beyond 

 the second practically impunctate on the dorsum, rather indistinctly punctate on 

 the venter, sixth ventral segment rather flat, smooth and distinctly punctured, 

 the punctures in the centre about as sparse as on the dorsum of the second ab- 

 dominal segment, adjoining near and above the posterior margin. 



Pubescence almost in to fine and silvery, that of the dorsum about as long as 

 the eye and about as sparse as the punctures, sides of the body with shorter con- 

 colorous pubescence on the venter, and to a great extent on the legs it is nearly 

 as long as on the dorsum. 



Color. — Sort of a dark testaceo-ferruginous, excepting the abdomen beyond the 

 petiole, part of the petiole, a spot within the ocelli a spot on each side of the pro- 

 thorax, femora, tibiae, middle and posterior metatarsi, all of wliich are more or 

 less dark brown, ocelli yellowish, eyes black, antenna;, coxae, trochanters and tarsi 

 more or less brownish testaceous, mandibles brownish testaceous, brown at tip.
