182 DERMAPTERA AND ORTHOPTERA FROM SINALOA, MEXICO 



more decided in area of costal veins and distad in anterior radiate fields. 

 Ventral surface and limbs translucent ochraceous-buff, the sternites heavily 

 suffused with opaque light buff. 



In coloration this species apjiarently closely resembles pdlucida. It is the 

 same generally as in C. panainae Hebard, which species is, however, more 

 richly colored with pronotal disk not unicolorous and showing other minor 

 differences. 



The measurements of the type are given first. Length of body, 9.4, 9 to 

 9.7; length of pronotum, 2.2, 2 to 2.2; width of pronotum, 3.4, 3.2 to 3.4; 

 length of tegmen, 9, 8.7 to 9.5; width of tegmen, 3, 2.9 to 3.1 mm. 



In addition to the type, a series of six male paratypes, bearing 

 the same data but taken from June 30 to August 6, 1918, has 

 been exa.aiined.

These specimens appear to agree in all important respects 

 with material recorded fro;m Guatemala and Costa Rica,^^ at 

 which tixne the Flavipennis Group was proposed and C. fusci- 

 pennis Hebard co.aipared with the present species. Both these 

 species have the median portion of the plate between the bases 

 of the styles produced dextrad in a small, stout spine, which 

 curves caudad. The styles in flavvpennis are broader and more 

 lamellate. 



The species is very plainly colored, the head immaculate^^ 

 and the general tone of coloration more reddish than in C. 

 translucida Saussure and its allies.

This series averages larger than the only other males we 

 have seen, one from Panama, the other from ('olombia. Careful

'^ In the majority of the series th(» intcrociilar area is unicolorous. In a 

 few specimens, however, there is n very weak indication of a broad, very 

 slightly darker, band.
