EL^OCHLORA, Stal. 



Eleeochlora, St&l, Ofv. Vet.-Akad. Forh. 1873, no. 4, p. 52 ; Recens. Orthopt. i. pp. 28,45 (1873);

This genus contains a number of large showy locusts that are distributed throughout 

 South America, from the northern parts of the United States of Colombia to the 

 Colorado River of Argentina. While no records or material at hand indicate its 

 occurrence within our region, it is quite likely that at least two species in their 

 distribution reach northward beyond the Isthmus. They are the following : — 



1. Elseochlora granulosa, St&l. 



Elceochlora granulosa, Stal, Obs. Orthopt. i. p. 28 (1875) 1 ; Pict. et Sauss. Cat. Acridiens, i. p. 15

2. Elaeochlora longispina, Pictet et Saussure.

DICTYOPHORUS, Thunberg. 



Dictyophorus , Thunberg, Mem. Acad. Petersb. v. p. 217 (1815); Stal, Recens. Orthopt. i. pp. 32, 



50 (1873) ; Syst. Acrid, i. p. 17 (1878). 

 Eomalea, Serville (in part.), Ann. Sci. Nat. xxii. p. 280 (1831) ; Hist. Orthopt. p. 621 (1839). 

 Rhomalea, Burmeister (in part.), Handb. Ent. ii. p. 619 (1838). 



While no definite records or specimens are at hand to warrant the inclusion of 

 Dictyophorus among Mexican Acridiens, the occurrence of two forms throughout all 

 the States of the Union bordering on the Gulf of Mexico seems sufficient reason for 

 placing it among the genera to be looked for in Mexico. 



1. Dictyophorus marci, Serville. 



Eomalea marci, Serv. Hist. Orthopt. p. 623 (1839) 1 ; Thomas, Acrid. N. Am. p. 180 (1873) 2 . 

 Dictyophorus marci, Bruner, Rep. U.S. Ent. Comm. iii. p. 58 (1883) 3 . 



Hab. Nokth America, Southern United States x ~ 3 . 



This insect is somewhat smaller and much darker coloured than the next species, 

 and is also much rarer. 



2. Dictyophorus micropterUS, Palisot de Beauvois. 



Acridium micropterum, Pal. Beauv. Ins. Afr. et Ame'r. p. 146, t. 4. fig. 4 (1805) \
