These specimens are all decidedly darker than any others we 

 have seen, being bister to very dark bister in general coloration. 

 This intensification of coloration may be ascribable to the some- 

 what less arid environment in which this series was probably 

 secured. 



CALOBLATTA Saussure

We are convinced that Saussure, misled by a certain amount 

 of superficial resemblance to Thyrsocera, incorrectly referred 

 this genus to the Pseudomopinae. 



Through differing to an extreme degree in wing venation, as 

 well as in pronotal contour and in other less important features, 

 nearest relationship is apparently with that section of the Cory- 

 diinae which includes Hypnorna and its allies. 



The material now before us, when compared with the second, 

 more detailed, description of Caloblatta, differs in having the 

 caudal margin of the pronotum very broadly convex, showing 

 scarcely. a trace of any "very weak median production"; the 

 veins of the discoidal field of the tegmina are not all longitudinal, 

 as these discoidal sectors become weakly oblique toward the 

 sutural margin, while weak spines are present on all the ventral 

 femoral margins. 



We here select the Costa Rican C. hicolor Saussure as geno- 

 type of Caloblatta. Examination of the type or additional 

 material, we believe, will show the species described below to 

 be congeneric, in spite of the apparently important differences 

 noted above. 



Caloblatta lampra new si)ecies (Plate VII, figures 6 and 7.) 



The antennae without annuli and rich ferruginous i)ron()tum 

 of this insect, with area between the latero -caudal sulci of the 

 disk suffused with carob brown, readily distinguish it from its 

 nearest relative, C. bicolor Saussure, described fi'om Costa Rica.
