5. Mgithus meridionalis. (Tab. IV. fig. 25.) 



JEgithus meridionalis, Crotch, Cist. Ent. i. p. 146 \ 



JEgithus cardinalis, var. C, Crotch, loc. cit. p. 146, et var. c, ibid. p. 493 2 . 



Hab. Beitish Honduras, Belize (Blancaneaux); Nicaeagua, Chon tales 1 (Janson, 

 Belt) ; Costa Eica * 2 , Cache, Irazu (Bogers) ; Panama, Bugaba, Vol can de Chiriqui 

 (Champion). 



Very short and convex ; the thorax distinctly shorter and more transverse than in 

 J$. cardinalis or 2E. politus, the sides very strongly narrowed and a little rounded. 

 Deep brick-red above, the antennae, legs, scutellum, and underside black ; specimens, 

 however, occur with the prosternum pitchy or even reddish. The upper surface is 

 entirely impunctate (with the exception of the epistome, which is alutaceous and 

 obsoletely punctate) and the elytra non-striate. There is the puncture and striola above 

 the antennal socket. The prosternum is not acuminate in the middle of the front, nor 

 much compressed. The metasternal line is distinct, carinate, running nearly across the 

 episterna, then deflexed and passing to the corner of the metasternum and merging in 

 its margin. 



There is some confusion about this species — Crotch's type specimen, bearing the 

 name JE. meridionalis in his own handwriting, is from Costa Eica, and has the 

 prosternum quite black. Again, although Crotch says the Chontales specimens all 

 pertain to 2E. meridionalis there is no specimen in his collection from that place, and 

 I have reason to think they were at least partly 2E. politus, Gorh., which he did not 

 distinguish. 



This insect is perfectly distinct from M. cardinalis, JE. rufipennis, &c. About a 

 dozen examples are before me.
