60 EKOTYLLD^. 



Mercedes, Cerro Zunil, Capetillo, Duenas, Chiacam, Senahu, San Juan in Vera Paz 

 (Champion). 



Among the Mycotreti with the body and elytra wholly red, this is one of the most 

 easily recognized, the legs being wholly black, and the coxae alone being of the colour 

 of the body. The punctuation is excessively fine. The metasternal and the abdominal 

 lines are very distinct, the latter long and plicate (i. e. raised at least on one side). 

 The sides of the metasternum and its episterna are impressed with a few large punc- 

 tures ; and the abdomen is also punctured, especially at the sides. The mentum is 

 distinctly pentagonal. The maxillary palpi are moderately widened at their apex. 



It appears to be a very common insect in Central America. 



The figure is taken from a Capetillo specimen. 



36. Mycotretus savignyi. 



Mycotretus Savignyi, Lac. Monogr. Erotyl. p. 156 1 ; Crotch, Cist. Ent. i. p. 145 2 . 



Edb. Mexico, Juquila, Toxpam (Salle) ; Nicaragua, Santo Domingo in Chontales 

 (Janson 2 ); Costa Rica (Van Patten); Panama, Bugaba, Volcan de Chiriqui (Cham- 

 pion). —South America, Colombia x 2 . 



The Costa Rican specimens are large, and there is a small form, which at the same 

 time seems more ovate, from the Volcan de Chiriqui; but I detect no important 

 difference in them, nor in the examples from Mexico. The latter locality is rather 

 unexpected, and Herr Hoge does not seem to have met with it. 



37. Mycotretus sobrinus.

Hah. Mexico, Toxpam (Salle). — Brazil 1 2 3 , Rio Janeiro, San Paulo. 



This species does not -appear to be common ; and the Mexican locality is interesting, 

 as I have not seen it from any of the intermediate countries. The femora are wide, 

 and the tibiae (especially the middle pair) widened. The abdominal lines are long 

 and plicate. Palpi very wide. 



38. Mycotretus aegrotus. 



Oblongus, parum ovatus, livide testaeeus ; capite prothoraceque minute crebre punctatis ; elytris punctato- 

 striatis, inters titiis vix punctatis; corpore subtus sublsevi, metasterno utrinque punctulato. Antennis 

 nigris, articulis tribus vel quatuor basi testaceis. Long. 5-6 millim. 



Hab. Costa Rica, Volcan de Irazu (Rogers). 



A species not very satisfactorily discriminated ; but which in its long form and fine 

 multipunctate elytral striae, pale colour, and punctured thorax may be compared to 

 M. luteipes. It is, however, much larger than that insect ; its thorax is much more
