I06 THE BLATTIDAE OF PANAMA 



Bello, has an additional minute black dot in the discoidal field 

 meso-proximad. 



The males have the eyes varying from subattingent to actually 

 attingent. The females have the interocular space varying from 

 slightly over one-third to slightly less than one-fourth the greatest 

 ocular depth, excepting one individual in which the interocular 

 space is distinctly narrower.

From the three line description of puiictum, we are led to believe 

 that this name is based on the large condition of exoleta here, dis- 

 cussed, which is found in northwestern South America and in 

 Central America. The interocular width is described as almost 

 greater than that of the eye in the type of punctum. This is. 

 considerably greater than in any female here discussed, but a 

 feature of decided variability in the present species and also known 

 to be exceedingly variable in the closely reXsited P. ciibens is Saussure. 



From cuhensis, males of exoleta are separable by the somewhat 

 moredepressedinter-ocular-ocellar area, '-Hhe stronger distal obtuse- 

 angulate emargination of the supra-anal plate, longer cerci, and 

 styles which are very minute, one-fifth to less than one-sixth as 

 long as the cerci (in cubensis one-third to about one-fourth as long 

 as the cerci). As has been noted, females are separable solely by 

 their average decidedly larger size. The margins of the pronotum 

 and marginal fields of the tegmina arc often slightly more opaque, 

 but this feature is not strikingly developed, shows some individual 

 variation and is on the whole of little value. 1^4 



Though males of exoleta from eastern Peru, Brazil and Argentina, 

 show but little greater size development than is usual in cubensis, 

 and females are only above the average, not above the maximum, 

 for that species, a male at hand from Alpayacu, Oriente, Ecuador, 

 and a large series of males from Bogota and Villavicensio, Cundi- 



'^■* This feature is not constant. It is distinctly apparent onl\,- in some series. 

 '-■* It is further to be noted that, in alcoholic material, this condition is decidedly inten- 

 sified.
