and segments 1-3 of the abdomen piceo-testaceous ; thorax canaliculate 

 behind, before the base transversely impressed, a little shorter than broad ; 

 abdomen slightly narrowed towards the base ; joints 1-3 deeply impressed 

 transversely; antennae and legs piceo-testaceous. Length, .10. One 

 specimen, Coney Island, near New York. Less elongate than the other 

 species, with fine punctures, especially of the thorax, less dense and more 

 distinct than in the two preceding species." (The two preceding species 

 are cavicollis and nigrella.) 



If my notes are correct, the specimen in the Leconte collection from 

 Coney Island is labelled ^^baiteata Lee." This undoubtedly good species 

 is recognizable amongst the eastern forms by the longitudinally, broadly, 

 entirely excavated prothorax of the male ; the first joint of the hind tarsi 

 is fully as long as joints 2 and 3 together, the species thus appearing as a 

 connecting link between Gnypeta and Tacky usa. Not closely related to 

 any other species of the northern hemisphere ; known to me from the 

 following localities : Mass. (Tyngsboro, Framingham) ; Penna. (Jeanette) ; 

 111. (Algonquin) ; Maine and New York. 



3. laticollis Csy. — The most common species of Gnypeta in Cali- 

 fornia, recognizable at once by the open middle acetabula. It is known 

 to me from Los Gatos, Pacific Grove, Nordhoff, S. Juan Capistrano, 

 Oceanside, Lakeside, Foster, S. Diego, Victorville, S. Bernardino, Elsinore, 

 Riverside, Pomona, Azusa, Pasadena, Sierra Madre, Mt. Wilson, Yuma, 

 all in California. I have also some specimens from El Paso, Texas, 

 which do not appear to be difi"erent from the California specimens. 



4. experta Csy. — Recognized by the male characters. The head 

 in this sex being broadly, almost entirely concave, and the prothorax 

 entirely concave in the middle. The females are somewhat different from 

 the males, especially in habitus, with apparently shorter antennae and a 

 trifle broader abdomen; they are consequently not easily recognized, 

 unless taken in company of males. 



5. linearis Csy. — I fail to find any reliable characters which would 

 separate linearis from experta, and- propose to unite these two forms 

 under the latter name. 



6. harfordi Csy. — In this species the male prothorax is obsoletely 

 depressed in about the basal two-thirds, the depression being shallow and 

 not as sharply limited as in experta. I believe I interpret this species cor- 

 rectly. I have seen specimens from Cole, Applegate, Nordhoff, Pasadena, 

 Lakeside and Foster, all in California. 



7. crebrepunctata Csy. — Apparently a good species, differing from 

 our other western forms chiefly by the much less shining surface and by the
