3. CAMPYLACANTHA SIMILIS, new species. 



(Plate IV, fig. 5.) 



Dark bluish f^reen, more or less infuseated and enlivened by various 

 shades of green. A broad, longitudinal, sordid yeHow stripe behind the 

 ui)per half of the eyes, beginning at their nearest approximation, leaves 

 on the top of the head a broad, ecjual, dark bluish green dorsal stripe: 

 the genae are more or less mottled with olivaceous and the antennae are 

 ferruginous, deeply infuscated. Pronotuin more or less deeply tinged 

 with dark olivaceous, the upper half of the lateral lobes of the prozona 

 alone pure bluish green, though the dorsum of the nietazona approaches 

 it. Tegmina dull green, infuscated basally, nearly or quite half as long 

 as the abdomen, subacuminate. Fore and middle femora dull ferru- 

 ginous, apically dark olivaceous; hind femora stouter than in the two 

 preceding species, bluish green on the outer face, slightly infuscated at 

 the incisures, greenish fuscous above feebly bifasciate with fuscous, 

 ^avo-luteous below and within, and with a feeble and broken testa- 

 ceous pregenicular aiinulus; hind tibiae pale bluish green, deepest at 

 base, followed by a dull luteous annulus and becoming lutescent api 

 cally, the spines tipped with black. 8upraaiial plate of male similar to 

 that of the two preceding species, but Hatter, with lower ridges; furcula 

 as there; cerci almost as long as the supraanal plate, tapering very 

 rapidly in the basal third, beyond slender, less than halt as broad as 

 the base, subequal, expanding feebly beyond the middle and then 

 tapering again, the lower portion of the tip very slightly produced and 

 very feebly curved downward ; infracercal idates much as in the preced- 

 ing species or perhaps broader basally. 



Length of body, male, 23.5 mm., female, 35 mm.; antennae, male, 

 female, 10.5 mm.; tegmina, male, mm., female, 11.5 mm. ; hind femora, 

 male, 13.5 mm., female, 17.5 mm. 



One male, 1 female. Lerdo, Durango, Mexico, November (L. Bruner). 



This species, though closely allied to the preceding, is distinguish 

 able from it not only by its colors, but by the greater stoutness of the 

 hind femora, more easily recognized than described.
