192 OETHOPTEEA. 



The length of the frontal horns and of the prothorax being somewhat variable in 

 Theoclytes, as also the shape of the elytra, we believe that the large specimen described 

 is only a variety of T. chlorophcea. 



2. Theoclytes maya, sp. n. (Theophytes chlorophcea, var., Tab. X. fig. 33.) 



T. chlorophcece afnnissima at minor, prothorace eodem modo elongato et gracili. 



$ . Frontis processus longissimus deplanatus, apicem versus haud attenuates, potius subdilatatus, inter cornua 

 anguste incisus, cornibus apice late rotundatis. Prothorax sparse granulatus, marginibus remote minute 

 denticulatis. Elytra et alse sensim ut in T. chlorophcea vel paulo breviora; alarum vena discoidali tantum 

 furcata. 



3 . Antennas serrato-moniliformes. Frontis processus valde brevior, apicem versus attenuatus, apice bidenta- 

 tus. Prothorax elongatus. Elytra et alse quam in maribus T. chlorophcea sensim breviora, campo 

 marginali et apice latius prasino-coriaoeis, punetis 2-3 fuscis. Alee campo anteriore angustiore, apice 

 anguste rotundato, ad margines inquinato, necnon puncto libero fusco ; vena discoidali ramosa. 



2 . Long. 58 ; pronot. 26, front, proc. 4, elytr. 30*5, latit. elytr. 10, camp. marg. 4-1 millim. 



3 . Long. 57-5 ; pronot. 26, front, proc. 2, elytr. 34, latit. elytr. 8-5, camp. marg. 2-5 millim. 



Hab. Mexico, Tabasco (H. H. Smith : 6 ), Temax in North Yucatan (Gaumer : $ ).

2 • Statura T. chlorophcece. Frons cornibus brevibus haud contiguis armata. Prothorax elongatus, tenuiter 

 denticulatus. Elytra campo marginali latiusculo, apice valde sinuato. Alae apice haud acute productae. 



Hab. South America, Colombia, Guiana, North Brazil ; Antilles, Cuba, Jamaica. 



We only know this species by Drury's figure. All the authors, except de Haan, have 

 confounded it with the insect figured by Stoll, Spectr. et Mantes, t. 9. fig. 32 (T. stolli). 

 It forms a transition from the type of T. chlorophcea to that of T. parallela, the elytra 

 being strongly sinuated at the end and the wings not pointed (as in T. chlorophcea), 

 while the head is only bituberculated (as in T. parallela *). 



Obs. — T. cingulata, Stoll, belongs to a different species (comp. T. stolli). Lichtenstein, 

 Serville, Burmeister, Guerin-Meneville, Saussure, and Westwood have confounded the 

 species of Drury and Stoll ; the synonymy of these authors must therefore be completely 

 excluded.]

 Theoclytes cingulata, Sauss. Me*m. Mex., Mantid. p. 174. 2 ( ? <J). 

 2 . Erons hreviter bidentata. Prothorax valde elongatus, subtiliter denticulatus. Elytrorum campus mar- 



* Perhaps the insect figured by Drury really represents T. chlorophcea, completed by affixing to it the head 

 of T. parallela ?
