In addition to the type we have before us, from the Academy 

 collection, a paratypic male from Cachi, Costa Rica, taken by 

 Mr. Lankester in January, 1914. This specimen shows no 

 really noteworthy differences from the type except in color, 

 which is mentioned in the above description. 



Coelophyllum peruvianum new species. (PI. XII, fig. 4.) 



Closely allied to C. crenulatum and costaricense, but more 

 particularly to costaricense, from which it differs chiefly in the 

 distinct and relatively .abrupt obtuse-angulation at the distal 

 third of the costal margin of the tegmina, in the more sub- 

 parallel major portions of the costal and sutural margins of the 

 same, in the smaller eye, in the less bullate and more weakly 

 compressed face, and in the shorter limbs. The tegminal form 

 is fully diagnostic of this species. 



Type. $ ; Chanchamayo, Peru. [Acad. Nat. Sci., Phila., 

 Type No. 5310.] 



Size moderately large; form compressed; surface smooth, of the 

 tegmina as in amasonicum and costaricense. 



Head with the interspace between the eyes subequal to the greatest 

 width of the eye ; fastigium acute, immediate apex narrowly rounded, 

 undulate depressed, deeply but narrowly sulcate, apex well separated 

 from the fastigium of the face; paired ocelli large; fastigium of face 

 relatively acute ; face moderately bullate, appreciably but not greatly 

 compressed: eyes broad ovate in basal outline, moderately compressed, 

 directed cephalad ; antennae elongate. 



Pronotum moderately compressed, the disk as in C. costaricense; 

 lateral lobes as in costaricense, but the humeral sinus is shallower 

 and more rectangulate, with the angle more broadly rounded. 



Tegmina as in costaricense. except for the following differences : 

 Narrower, the greatest width contained faintly more than two and 

 one-half times in the greatest length of the same; costal and sutural 

 margins in large part subparallel ; costal margin with the distal third 

 quite sharply oblique truncate to the apex, which is narrowly rounded 

 rectangulate ; sutural margin straighter than in costaricense : stridu- 

 lating field relatively shorter and broader than in costaricense, the free 

 margin more arcuate distad of the stridulating vein. Wings very 

 faintly surpassing the apices of the tegmina. 



Disto-dorsal abdominal segment as in costaricense: cerci of the usual 

 type but more slender than in costaricense, less incrassate proximad 

 and tapering more regularly: subgenita! plate of the type usual in the 

 genus, the distal margin U-emarginate.
