The présent species approaches most closely an insect in the 

 collection of the Carnegie Museum from Para, Brazil, but differs 

 from it both in color and some structural features. 



Poecilocioeus, кеп. nov. 



A member ot the group Coscineutae and related to Annicer- 

 ris S t â 1 and Zosperamerus В r u n e r, but differing from both of 

 them in several respects as will be seen by an examination of the 

 subjoined diagnosis of the type species. 



Poecilocioeus ornatus. sp. n. 



Size medium, the head of moderate size, about as wide as the 

 anterior edge of the pronotum which embraces it almost to the 

 eyes: the vertex rather narrow, in the female a trifle less than the 

 width of the frontal costa between the base of the antennae; the 

 fastigium subhoi'izontal, a little longer than wide. its disk flattened 

 and provided with a minute transverse impression just back of the 

 extreme anterior edge where it meets the upper extremity of the 

 frontal Costa. Latter fairly prominent betлveen the antennae, not 

 sulcate above the ocellus, but provided with a few punctures. much 

 less prominent below and shallowly sulcate, fading before reaching 

 the clypeus: facial carinae not especially prominent, divergent. Eyes 

 not large, somewliat bulging. a little longer thaii wide. Anterior 

 lobe of the pronotum subcylindrical, the bind lobe divergent, a 

 little more than one-half the length of the anterior one but much 

 more profusely punctulate; anterior edge rather coarsely margined, 

 undulate, bind edge of disk obtusangulate, the transverse sulci pro- 

 found. Tegmina coriaceous, rather coarsely and j)rofusely veined, 

 about as long as the abdomen, the apex rounded; wings vitreous, 

 infuscated apically, the apex broad, nearly truncate. Abdomen cari- 

 nate, cylindrical, nearly equal troughout, the apex rather abruptly 

 acuminate; the valves of the ovipositor slight, rather straight and 

 the lower pair embraced by the upper ones. Prosternai spine gross, 

 transverse, quadrate, with a minute wart-like protubérance at middle 

 near the posterior edge. Space between meso- and metasternal lobes 

 transverse. Hind femora ratiier slender, their apex about equal ling 

 that of the abdomen, genicular lobes slightly acuminate, the bind 

 tibiae six-spined externally, eight-spined internally, the first and
