338 MANTIDAE AND PHASMIDAE OF PANAMA 



Rio Trinidad, Panama, III, 18, and V, 9, 1911, (Busck), 

 2 small juv. 



Compared with Colombian and Brazilian adults,^" these im- 

 mature individuals, only 24 and 26.5 mm. in length, agree closely 

 in general form, the peculiar parallel sides of the pronotal 

 supra-coxal expansion being distinctive. As in the adults, 

 minute black flecks are found on the inner face of the cephalic 

 trochanters and proximad on the same face of the cephalic fem- 

 ora, while the first discoidal spine is also marked with black.

A series of twenty-four specimens now before us, representing 

 localities from Nicaragua to Ecuador, are clearly referable to 

 but a single species. This species varies somewhat in size, 

 pronotal outline, tegminal width, and decidedly in the extent of 

 the black spot at the unguicular sulcus on the internal surfaces 

 of the cephalic femora. Differences in these features led Wood- 

 Mason to describe servillei^^ and hrunneri. After comparison of 

 the material at hand with the original descriptions, we do not 

 hesitate to indicate the above synonymy. The individuals 

 before us show many different gradations between the conditions 

 which Wood-Mason believed to represent distinct species. ^^

" We have already stated that Saussure and Zehntner's separation of 

 servillei and rhombicollis had no value. Trans. Amer. Ent. Soc, xlv, 

 p. 130, (1919). 



12 Kirby, in his catalogue, places rhombicollis of Wood-Mason and subse- 

 quent authors (not of Latreille) under peruviana Serville, We do not believe 

 he had sufficient evidence to warrant such action, but should it i)rove correct, 

 peruviana also would fall as a synonym of rhombicollis (Latreille).
