168 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



The series enables us to associate the sexes with Kttle difficulty. 

 In length little difference between these occurs. 



The males are readily distinguished from those of L. molita 

 (Westwood) by the average decidedly smaller size, much shorter 

 antennae, which extend only to base of abdomen, more inflated 

 disto-dorsal abdominal segment, which is strongly transverse, 

 absence of acute-angulate projection of latero-caudal angle of 

 preceding segment (shown by males of that species at hand and 

 excellently figured by Westwood for the type) and more roughly 

 nodose ventro-caudal surface of subgenital plate. 



The females differ from those of molita in average decidedly 

 smaller size, with antennae shorter, extending only to base of 

 abdomen, and in being somewhat less attenuate, the multicarinate 

 condition of the dorsal surface of the abdomen more pronounced 

 and the pronotum and mesonotum being heavily acute-nodulose 

 to varying degrees in all but pale examples, in some of which these 

 portions are fully as smooth as in molita. 



The present series shows conclusively the development of both 

 green (yellowish in dried material) and brown color phases in the 

 female sex and that, in the green condition, the pronotum, meso- 

 notum and metanotum become much smoother.

In addition to the series recorded there is a male from San 

 Antonio, taken in October, agreeing in every genital feature and 

 with the majority in size. In this specimen, however, the occiput 

 bears three minute blunt denticulations latero-dorsad on each 

 side, while in addition to minute twin dark macuhitions nieso- 

 caudad on each dorsal al)donnnal segment, the second segment 

 bears twin minute blunt denticulations at this point. The impor- 

 tance of these features can not be determined and if the specimen 

 is referable to a different species we are at present unable to place 

 it.
