GRASSHOPPERS OF THE CONALCAEA COMPLEX— GURNEY 303 



Male. — General form as in humphreysii; hind femur clearly 

 more robust than in poecilus and slightly more so than in hum- 

 phreysii; cercus (fig. 64, k) broadly produced ventroapically, 

 moderately concave mesally; furcula and supra-anal plate about 

 as in figure 64, m, of cochisei; epiphallus as in poeciliLs; dorsal 

 valves of aedeagus broad, narrowing but little at base, contiguous 

 apically (fig. 64, /) . 



Coloration : All the material examined was originally preserved 

 in alcohol, so that discoloration has occurred. The pattern is the 

 same as that of related species, except that the postocular black 

 bar is unbroken on the prozona of the lateral lobes of the prono- 

 tum, and there is a trace of the bar on the metazona. A diffusion 

 of dark pigment may have occurred while immersed in fluid, and 

 these distinctions may not be typical of fresh specimens. 



Measurements (length in millimeters) of a topotype: Body, 

 26.5; pronotum, 6.3; front femur, 5.7; hind femur, 16.8. 



Female. — As in male except for genital features and greater 

 robustness. 



Measurements (length in millimeters) of a topotype: Body, 30; 

 pronotum, 7:5; front femur, 5.5; hind femur, 19.5; tegmen, 5.8. 

 Body length of females examined varies from 30 to 40 mm., pro- 

 notal length from 7.5 to 8.5. 

 I Type. — A unique male noted by Scudder (1897) ; also by Rehn 

 and Hebard (1912). In Academy of Natural Sciences of Phila- 

 ^ delphia. 

 P Type locality. — San Jose del Cabo, Baja California. 



In addition to the type, I have examined two males and two 

 females labeled as topotypes and marked "taken with type." Like 

 the type, they bear the locality label "San Jose del Cabo, Baja Cali- 

 fornia. G. Eisen Coll." The type also bears a "drawn" label, show- 

 ing that it was illustrated by Scudder. One additional male, three 

 females, and three nymphs bear identical locality labels but are 

 not marked as topotypes. The topotype labels were probably af- 

 fixed in recent years by Mr. Hebard, and probably the whole series 

 is equally deserving of topotypic designation. Although no col- 

 lecting date is carried by these specimens, it is known that Gus- 

 tavus A. Eisen collected in Baja California during the years 

 1892-'94. 



Also preserved in the Academy of Natural Sciences of Phila- 

 delphia is the female allotjrpe of Melanoplus nitidus Scudder, col- 

 lected by John Xantus at Cape St. Lucas, Baja California. That 

 species has been referred to Sinaloa by Hebard (1917), but he 

 found that the type and allotype were not congeneric, even as 

 Scudder himself had suspected. The entire available series of 

 cras8us was originally preserved in alcohoL
