302 BKAZILIAN ORTHOPTERA 



The type of this remarkable species is unique. It may require 

 generic separation when more is known of the other species of 

 Sitalces, but its affinity is most certainly with that genus. 



Cocama tripunctata new species 



Allied to C. trivittata Giglio-Tos, the type of the genus, having 

 the general form similar, the proportions in the same ratio and 

 the lateral lobes of ^he pronotum with pale callose areas, but 

 differing in the striping being reduced to a blackish postocular 

 line continued over the pronotum to the apices of the tegmina, 

 in the lateral lobes having two instead of one yellow callose area 

 and in a similar one being placed on the metapleura, in the frontal 

 costa being broader at its junction with the fastigium, in the 

 deep red of the greater portion of the caudal femora and in the 

 green caudal tibiae and distal extremity of the femora. 



Type.— 9; Parc4, State of Para, Brazil. (C. F. Baker.) 

 [Acad. Nat. 8ci. Phila., Type no. 5290.] 



Size medium; foi-m robust, subfusiform; surface of head, pronotum and i)leura 

 more or less rugulose, of abdomen, venter and caudal limbs smooth or sparsely 

 punctate. Head with the exposed dorsal surface equal to about two-thirds 

 the length of the dorsum of the pronotimi : occiput arcuate inflated, moderately 

 elevated dorsad of the pronotal disk, regularly arcuate declivent to the fasti- 

 gium; interocular portion of the vertex narrow, no wider than the proximal 

 section of the second antennal joint, faintly sulcate: fastigium subhorizontal, 

 faintly declivent, moderately produced, trigonal in outline, as broad as long, 

 very faintly impressed within its margins, very weakly and shallowlj' broad 

 sulcate; fastigio-facial angle rounded when seen from the side, the cephalic 

 section of the interantennal protuberance arcuato-truncate and ventrad regu- 

 larly arcuate into the decidedly retreating and concave facial line; frontal 

 costa between the antennae no wider than the proximal antennal joint, sub- 

 equal in width, plane and sparse punctate, except immediately dorsad of ocellus 

 where it is irregularly sulcate, briefly constricted ventrad of the ocellus and 

 indicated to the clypeal suture, but the margins, which are subcarinate, are 

 irregular and broken, this section irregular sulcate; genae with some irregular, 

 low, strumose ridges and points: eyes prominent, moderately exserted when 

 seen from the dorsum, hardly elevated above the dorsal line of the head when 

 seen from the side, in basal outline elliptico-ovate, slightly flattened, in depth 

 nearly half again that of the infra-o(;ular portion of the genae: antennae as long 

 as the head and pronotum together, rather heavy, subdepressed. Pronotum 

 subcylindrical, moderately enlarging (;audad on the metazona, prozona subequal 

 in width, weakly sollate when seen from the side, surface of i)rozona coarsely 

 rugose impresso-punctate, on metazona closely and finely cril)roso-pun('tate; 

 cephalic width of pronotum no narrower than the caudal section of the head: 

 cephalic margin of pronotal disk weakly arcuate with a very faint median siima- 

 tion, caudal margin of disk very broadly and bluntly obtuse-angulate, faintly
