MTCOTEETTJS. 49 



long, nearly reaching to the margin of the basal segment ; metasternal lines are evident 

 in Cayenne examples, but I do not see them in the Guatemalan specimens. 



M. leopardus, Kirsch, from Peru, is smaller, and has the markings large and more 

 condensed ; it also has the normal nine spots on the thorax in some specimens, and may 

 be regarded as distinct. 



Mr. Champion captured five specimens at San Geronimo.

Olivier's figure, though very poor, is perhaps sufficient for the identification of this 

 insect. The number of spots on the thorax is apparently variable : in some Cayenne 

 specimens the two basal ones are united. The quadrate spot on the elytra behind the 

 scutellum is often, but not always, divided by the suture, it being yellow at that 

 part. 



5. Mycotretus fasciolatus. 



Mycotretus fasciolatus, Lac. Monogr. Erotyl. p. 150 \ 



Eab. Mexico 1 , Cordova (Edge), Toxpam (Salle); Guatemala, Chacoj, Sabo, and 

 San Juan in Vera Paz (Champion) ; Panama, Bugaba (Champion). 



The thorax sometimes is spotless : there are usually four spots arranged in a square. 

 The elytral fascia varies in width, the other markings are more or less obliterated. 

 Many specimens. 



6. Mycotretus scitulus. 



Mycotretus scitulus, Lac. Monogr. Erotyl. p. 154 * ; Crotch, Cist. Ent. i. p. 454 \ 



Hab. Mexico 2 , Toxpam (SalU); Costa Eica (Van Patten). — Colombia, Bogota 2 ; 

 Amazons, Ega 2 ; Brazil, Eio Janeiro x 2 . 



Var. Minor, elytrorum epipleuris nigris. 



Hab. Guatemala, Capetillo, Cerro Zunil (Champion). 



This variety has a better claim to specific rank than some others which have been so 

 honoured, on account of the black epipleurae, a difference which in the Erotylidse often 

 indicates a species ; but I do not regard this Guatemalan form as being more than a 

 local race of M. scitulus.
