eyes as from (>aeli other; space between and including the ocelli black. 

 The scape and funicle joint of antennae honey yellow, the former 

 coarsely punctate and pubescent with longish yellowish hairs; flagellum 

 piceous and covered with a dense short white tonientum; first joint of 

 flagellum three-fourths of the length of the second. Mandibles with 

 comparatively few yellowish and brown hairs, with an emargination 

 on the lower border which is subtended by an obtuse tooth; the tip is 

 black and bidentate. The maxillary palpi have articles II and III of 

 equal length, IV and V of equal length and a little shorter. Thorax 

 white pubescent except above and in front where the hairs are yellow- 

 ish and brown. Sutures of pronotum without »plumose hairs. Mesonotuni 

 shining and with very large and close punctures, becoming rugosely 

 punctured on the sides; with two rather distant, distinct, longitudinal 

 grooves on either side, but these do not reach the anterior margin. 

 Seutellum opaque, coarsely rugose. Metanotum shining, very coarsely 

 reticulated; the meshes of the reticukun subequal except for two unsy- 

 metrical long narrow ones in the middle above. Mesosternum rugoso- 

 punctate and armed with two short teeth near the median line. Legs 

 honey yellow, a shade darker on apices of hind femora and tarsi and 

 on mid and hind tibiae. Tegulae honey yellow. Fore wings with the 

 apical third pale smoky; nervures dark, stigma piceous, apex of margin- 

 al cell obtusely pointed; first recurrent nervure entering second sub- 

 marginal cell before the middle of its lower margin; transverso-median 

 nervure joining the externo-median in front of the basal. 



Abdomen shining, and rather densely clothed with white, yellowish, 

 and brown hairs. The length of first segment viewed from above Is 

 less than twice its breadth at apex, the sides are not straight, for apical- 

 ly it is swollen to almost nodose, though it is not as strongly constricted 

 at juncture with second as in some other species; basally this segmeni 

 is rugoso-punctate but on the nodose portion very sparsely and remotely 

 punctate; near its apex are a few plumose hairs; the median ventral 

 ridge is not prominent and is bisinuate. Pubescence on first and second 

 segments thick and whitish above and below; the apical margins of 

 segments II to V are provided with dense rows of yellowish plumose 

 hairs; segments III and following are finely transversely aciculate, 

 and finely punctate apieally. The last dorsal segment is opaque, thickly 

 finely punctured, nearly nude, and with tufts of golden hairs at apical 

 angles. Second segment with the usual felt lines and third segment with 

 the usual speculum. 



In Viereck's synopsis this species would fall into the concolor of 

 Cresson, but differs widely from mellicornis which also runs to the 

 same species. The type was taken at Claremont, California. It is named 

 for Prof. A. J. Cook, one of the oldest American entomologists, who 

 is now living at Claremont.
