176 GENUS CARIBLATTA (oRTHOPTERa) 



plate moderately produced, the lateral portions bent strongly 

 ujDward leaving lateral margins dorsal in position; the short 

 remaining median portion j^rojecting caudad beneath the lateral 

 portions which, curving mesad, nearly meet above it. This short 

 median portion has the distal margin briefly curved upward and 

 nearly transverse. At the base of the sinistral cleft between 

 the lateral and mesal portions, is situated a chitinous thorn, 

 curving regularly upward with sharp apex adjacent to the apex 

 of the sinistro-lateral portion; at the base of the dextral cleft, is 

 situated a rounded knob, slightly wider than long, with dorsal 

 surface covered with small chitinous spines.^' The form of the 

 subgenital plate is symmetrical and is such that with the supra- 

 anal plate, when in normal position, the specialized styles are 

 almost hidden and the anal orifice nearly closed. 



9 . Agrees with male except in the following features. Form 

 very slightly less slender. Supra-anal plate very small, strongly 

 transverse, weakly produced, with distal margin broadly convex 

 but showing a rather broad, shallow median concavity. Sub- 

 genital plate similar to that of pundulata but with distal median 

 portion somewhat wider.^^

Coloration. — Head with vertex dark mummy brown to near 

 point of narrowest interocular space, thence a large cream colored 

 marking extends nearly to base of the antennae and is terminated 

 ventrad by four rounded projections, its form thus resembling an 

 inverted crown,^^ ventrad this is mummy brown with a median 



^^ It is evident that these projections represent the styles in this distinctive 

 species; the sinistral being of a type found nowhere else in the genus, but the 

 dextral is similar to those found in reticulosa, punctulata and cuprea. 



2^ Females of the species are more readily separated by the distinctive 

 features of coloration rather than by structural characters. 



23 The lateral projections of this inverted crown are in part formed by the 

 cream colored ocellar spots, this fusion making the latter inconspicuous.
