Dec, 19-2^.] Wolcott: The Male of Cymatodera Horni. 



193 



Santa Rita Mountains, Arizona, 5,000-8,000 ft. The male from 

 which the foregoing characters are derived is from Phoenix, Ari- 

 zona; it is (No. 1230) in my collection and is designated as the 

 allotype of the species.

Text-figure, i and 2. Cymatodera horni W'olc, terminal dorsal and ven- 

 tral segments of abdomen, male. 3 and 4. C californica Horn, the same. 

 5. C, horni Wolc, edeagophore, dorsal view. 



The allotype is 21.0 mm. in length; 5.5 mm. in width at widest 

 part, one fourth from elytral apices, and exactly 5.0 mm. in width 

 at the humeri. 



In both C. horni and C. californica the lobes of the sixth dorsal 

 segment are rather densely clothed with long, pale yellowish, poste- 

 riorly directed hairs; these are purposely omitted in the figures as 

 their presence would serve to obscure the outline of the parts in- 

 volved. The " median fascia " of the elytra is not median, properly 

 speaking, but distinctly ante-median in both the present species. 



Believing that an examination of the primary sexual characters 

 of the male would reveal some distinctive features, I had the edeago- 

 phore removed from a specimen of C. horni and C. californica, but the 

 results viewed from a tanonomical point proved very disappointing, 

 as the organs were found to be practically identical in all details, 

 with, the exception that in C. horni the apex of the apicale is obtusely 

 rounded while in C. californica the apex is somewhat conical ; in 

 both species the distal portion is feebly deflected.
