one simply for the month of July. This male seems to agree fairly 

 well with Beutenmiiller's CEcanthus pini. Could it not be possible 

 that this specimen of a local species became mixed with the South 

 American material at the time of pinning and labeling?

The insects which constitute this genus are found over a consider- 

 able portion of temperate and tropical North America and in tropical 

 South America from Colombia to eastern Brazil. Only three species 

 are known, two of which are now described for the first time. In 

 general appearance they resemble the larger and slenderer species 

 of the genus CEcanthus, from which they differ in such characters as 

 mentioned on a former page in the synoptical key for separating 

 the American genera of the family CEcanthidse. Nowhere do these 

 insects seem to be abundant or even common. In habit they are 

 supposed to be similar to the tree-crickets belonging to the genus 

 CEcanthus. 



A. Size smaller, graceful (male, length to tip of wings 20 mm.). Pronotum 

 little, if any, wider at the base than at the apex; veining of the tegmina 

 quite regular and uniform, the veins slender [Rio de Janeiro, Brazil]. 



obscurifrons sp. nov. 

 AA. Size larger, more robust (female, length to tip of wings 25 mm.). Pronotum 

 decidedly wider at its base than at the apex; veining of the tegmina some- 

 what irregular, some of the veins enlarged. 

 b. Tegmina without markedly robust oblique veins on the dorsum, marked 

 above on each elytron with a prominent median and anterior fuscous 

 blotch. [Mexico, Central America, and the United States east of the 



Plains] bipunctata De Geer. 



hb. Tegmina furnished with robust oblique veins on the dorsum, these veins 

 infuscated [Colombia] meridionalis sp. nov. 



69. Neoxabea obscurifrons sp. nov. 



Having the same general form, but plainly smaller than both N. 

 bipunctata and N. meridionalis, which latter is also described in this 

 paper. 



Head plainly broader than the anterior edge of the pronotum; eyes 

 rathr prominent and with the facets moderately large, giving to them
