Anomalon sp. 



There is a smaller specimen, No. 2257 M. C. Z., Florissant, Col. 

 (No. 9070, S. H. Scudder Coll.) belonging to this genus or to one 

 closely related, apparently different from the ones described, but too 

 poorly preserved to be, identified with certainty. It is black, with a 

 reddish abdomen and measures only 5.5 mm. in length. 



Barylypa primigena, sp. nov. 



Female. Length 8 mm. Dark colored, the abdomen unicolored; more 

 brownish. Wings slightly infuscated. Antennae long setaceous, reaching to 

 the tip of the petiole of the abdomen. Thorax gently sloping behind, the 

 metanotum rugulose near the tip. Parapsidal furrows present. Abdomen 

 strongly compressed apically, suddenly enlarged from the base of the third 

 segment; fifth and sixth segments higher than the height of the thorax when 

 seen in profile. Ovipositor projecting to a distance equal to the length of the 

 sixth abdominal segment. Petiole and second segment both slender, of about 

 equal length, the first but little swollen at the apex, the second gradually 

 broadened, third a little longer than high at the tip; fourth similarly shaped, 

 but nearly three times as high at the tip as the third; the next two a little 

 higher, about equal; seventh not so high. Posterior legs rather stout, the 

 femora slightly clavate, no broader than the tibiae. Metatarsus thickened. 

 Wings slightly, but distinctly infuscated, stigma moderately narrow, lanceo- 

 late. Venation not very well preserved, but the second recurrent nervure 

 appears to be very nearly interstitial with the transverse cubitus; submedian 

 cell considerably longer than the median. 



Type.— No. 2258, M. C. Z., Florissant, Col. (No. 13,934, S. H. 

 Scudder Coll.). 



Although the wing venation of the specimen is somewhat obscure, 

 the body has the habitus of Barylypa and all characters discernible 

 point to its location in this genus. 



Exochilum inusitatum, sp. nov. 



Female. Length 8-9 mm. Dark colored, the abdomen beyond the second 

 segment more or less brownish or dark yellow, especially below. Face and 

 four anterior legs also paler. Antennae short and rather stout, scarcely 

 over one-half the length of the body; with about 32 joints and not much 

 attenuated at the tips. Joints near the base of the flagellum fully twice as 

 long as thick; those near the middle quadrate, and those near the apex dis- 

 tinctly longer than wide. Mesonotum and mesopleurae smooth and shining.
