458 The Ohio Naturalist. [Vol. IX, No. 5, 



It will be noticed that while a considerable number of species 

 in this list corresponds with the nearctic representatives of our 

 own latitude, the great majority are different. A considerable 

 number are South American and so far as records show manv are 

 restricted in range to the Central American region. While these 

 records will be of service in deductions concerning the relation- 

 ship of this fauna it is not my purpose here to go into any dis- 

 cussion of the geographical affinities. This can better be done 

 in connection with discussions of the geographical range in par- 

 ticular families. 



MEMBRACIDAE. 



Pterygia bituberculata Fowl. 



One good example of this species from Los Amates agrees 

 closely with Fowler's description and figure. I have not seen 

 hispida Fairmaire and cannot determine as to distinctness of 

 the two species. 



Sphongophorus ballista. 



Taken at Puerto Barrios, March 3d, and Livingston , March 5, 

 1905. Certainly one of the most grotesque of this peculiar group. 



Bolbonota pictipennis Fairm. 



From Puerto Barrios, March 3d. 



Tylopelta gibbera Stal. 



Puerto Barrios, March 3d, evidently fairly common, the 

 collection including nine examples. 



Aconophora temaxia Fowler. 



Four females, six males Puerto Barrios, March 3d. 



Fowler's description is based on three females only. The 

 males associated here differ from the females in being smaller 

 and of a darker color the pronotal horn slightly shorter but 

 otherwise very similar. 



Aconophora nigra Stal. 



A single specimen from Puerto Barrios, March 3d, and one 

 from Mazatenango Feb. 3d. 

 Hyphonoe asphaltina Fairm. 



A number of specimens of this common species from Puerto 

 Barrios, and Los Amates. These show quite a little variation 

 in size and convexity of anterior face of pronotum. 



Acutalis fusconervosa Fairm. 



One specimen, collected at Los Amates in February, and four 

 from Mazatenango February- 3d. The anterior face of pronotum 

 is decidedly tawny. 



Micrutalis lugubrina Stal. * 



One specimen, Los Amates, is referred here. In some points 

 it agrees with the variety, parallela of Fowler.
