one of the lateral ocelli to the anterior ocellus. Clypeus very slightly 

 notched in the middle; the apical joint of the maxillary palpi distinctly 

 shorter than the preceding one. Front and the vertex very closely 

 granular, opaque ; the cheeks shining very finely punctured. Antennae 

 rather sparsely clothed with white hairs; the third joint a little longer 

 than the fourth ; the apical joints normal, the apical one about the 

 same length as the preceding one. Pronotum slightly notched in the 

 middle ; dorsulum closely, finely punctured ; the suture between the 

 dorsulum and the scutellum strongly striolated ; the scutellum more 

 finely and sparsely punctured than the dorsulum, and separated from 

 the postscutellum by a striolated furrow; mesothorax shining, with 

 some fine punctures and some larger punctures intermixed. Enclosure 

 of the metanotum distinctly defined, channeled by a longitudinal fur- 

 row, and the basal half with strong longitudinal striae ; the posterior 

 face with some large punctures ; the metapleurae shining. Legs very 

 weakly spined. The transverse cubitus of the hind wings interstitial 

 with the transverse median. The first abdominal segment much smaller 

 than the second, coarctate at the apex ; the second segment subglobose, 

 shining, with a few scattered punctures. The apex of the abdomen 

 with two spines (it may be that there are normally three and that one 

 of them is broken off) ; ventral plate not bifid. Color black ; labrum, 

 clypeus except two basal spots, face below the antennae, inner orbits 

 almost to top of the eyes, spot below the eyes, base of the mandibles, 

 scape beneath, line on the pronotum, tubercles, spot below the tegulae, 

 line on the scutellum, an indication of a line on the postscutellum, a 

 band on the first four abdominal segments (on the second it is inter- 

 rupted into two elongate spots), bands on the second and third ven- 

 tral segments (slightly interrupted medially), and lateral spots on the 

 fourth ventral segment, Icnwn-yelloiv. Legs mostly yellow; four an- 

 terior coxae, trochanters and femora above black ; posterior coxae 

 mostly black ; the posterior legs and a few spots on the intermediate 

 pair ferruginous. Flagellum with a fulvous tinge beneath. Wings 

 hyaline, radial and subradial area slightly clouded ; venation brown, 

 most of the stigma luteous. Sides of the thorax and the front with 

 short white hair. 



Type Locality : Campus of the University of Colorado, 

 Boulder. Named for Prof. T. D. A. Cockerell who collected 

 the single specimen July 27, 1908. 



This is a very distinct species. In the shape of the first 

 abdominal segment it is related to bipnnctatus Say, but it is 

 widely different from that .species in the more abundant 

 yellow markings. Tt does not exactly tit any of the genera 

 defined by Dr. Ashmead, but is perhaps closest to Hoplisus.
