1874.] 265 iScudder. 



ance. Apical half of the spines on the legs dusky, deepening into 

 blackish toward the tip. Ovipositor slender, pretty regularly but 

 not very strongly curved upward, finely pointed, the upper edge a 

 little protuberant near the base and beyond that very minutely and 

 distinctly denticulate; lower edge regularly curved, the apical fourth 

 minutely and retrorsely denticulate. 



Length of antennas, 103 mm.; of tegmina, 41.5 mm.; of hind tibia?, 

 26 mm.; of ovipositor, 12 mm. 1 ?, Eastern slope of the Peruvian 

 Andes. 



14. Conocephalus infuscatus nov. sp. 



Allied to C. tenuicauda Scudd., and C. exaltatus Walk. Smoky 

 brown, the under surfaces of all the femora blackish, the apical 

 half of the tibia? increasingly fuliginous, the tarsi dark fuscous; 

 ovipositor castaneous, becoming infuscated toward the tip, espe- 

 cially along the edges and the median line; wings hyaline, but the 

 veins smoky brown. Head and thorax rugulose, the latter with 

 more or less dusky mottlings. Tubercle of vertex stout, blunt, 

 scarcely longer than broad, extending nearly as far beyond the front 

 border of the eye as it is beyond the front of pronotum, rounded, 

 with a short, blunt, conical, depending tooth and a dusky transverse 

 line below the middle of the front. Ovipositor slender, shorter than 

 the body. Cerci short, slender, tapering more rapidly next the 

 pointed tip. 



Length of body, 30 mm.; of tegmina, 44 mm. ; of hind tibia?, 26.5 

 mm.; of ovipositor, 22.75 mm. 1 ?, Eastern slope of the Peruvian 

 Andes. 



15. Orchelimum Ortoni nov. sp. 



Almost wholly unicolorous, judging from a specimen dried after 

 immersion in alcohol; the tibia? and tarsi, especially the tips of the 

 tarsal joints, dusky; antenna? wholly dusky, excepting near the base. 

 A very slender species, with the fastigium of the vertex pinched at 

 its base, so as to be no more than half as broad as at summit. Teg- 

 mina slender, reaching, when at rest, a little further back than the 

 ovipositor, wings when closed extending still further beyond the 

 tegmina. Legs slender, the fore and middle tibia? with black-tipped, 

 the hind tibia? with wholly black spines. Ovipositor nearly straight, 

 slightly curved upward at its pointed tip. 



Length of body, 14 mm.; of antenna?, 47 mm.; of hind tibia?, 14 

 mm.; of ovipositor, 9 mm.; distance of tip of closed wings from hind 

 edge of pronotum, 22.25 mm. 1 ?, Peruvian Maraiion.
