1912] Caudell — Notes on the Mantid Genus Gonatista Sauss 161 



1. Larger, length of elytra over 30 mm.; maculation of elytra consisting of small 



spots and larger splotches, the latter predominating 2 



Smaller, length of elytra not over 30 mm. ; maculation of elytra consisting mostly 

 or almost wholly of small spots phryganoides Serv. 



2. Medium in size, the elytra from 32 to 40 mm. in length 3 



Of large size, the elytra 45 mm. or more in length major sp. nov. 



3. Elytra less densely maculate, distinctly less than one half of the total surface 



infuscated grisea Fabr. 



Elytra more densely maculate, about one half the total surface infuscated. 



reticulata Thunb, 



Gonatista grisea Fabr. 



This is the form found in the United States and I have material 

 only from within our borders, though it also surely occurs in Mex- 

 ico and West Indies. It is of medium size and the elytra are 

 sparsely maculate with spots and splotches, the infuscation covering 

 distinctly less than one half of the total area. The measurements 

 are as folows: Length, pronotum, cf , 9-10 mm., 9 9-11 mm.; 

 elytra, cf , 32-35 mm., 9 18-23 mm. 



Gonatista reticulata Thunberg. 



This species is represented in the collection of the National 

 Museum by two males from Porto Rico. It is closest to grisea 

 but the two specimens before me are lighter in color and the infus- 

 cation of the elytra is moi'e profuse, covering about one half the 

 total area. It is also a little larger. I place bifasciata Haan and 

 cubensis Saussure as synonyms of this form. The measurements 

 of the two males studied by me are as follows : Length, pronotum, 

 11-12 mm.; elytra, 36-40 mm. 



Gonatista major .sp. nov. 



In general color this species is lighter than either of the preceding 

 ones and is decidedly larger than either of them. The infuscation 

 of the elytra is no more profuse than in grisea but is gathered in 

 decidedly larger blotches, in this respect more like reticulata. 

 The female is unknown to me. The measurements of the males 

 are as follows: 



Length, pronotum, 13.5-14.5 mm.; elytra, 45-48 mm.
