MYCOTEETUS. ' 59 



and is, indeed, in a manner intermediate, it is quite distinct, and is probably one of a 

 series of closely allied species. The colour is rusty-red. M. luteolus is less narrowed 

 behind than M. cruentus; the punctuation of the thorax is thicker; the episterna 

 are wholly yellow ; and the fine punctures in the striae are fuscous, which gives them a 

 lineate appearance : I do not find the latter, however, a character of importance, and it 

 sometimes occurs in various species of red and yellow Triplacides. 



33. Mycotretus cruentus. (Tab. III. fig. 22.) 



Oblongus, postice paullulum angustatus, saturate sanguineus ; prothorace minute parcius punctulato ; antennis 

 (basi excepta), pedibus et episternis metasternalibus nigris, his laevibus. Long. 6 millim. 



Hab. Guatemala, Zapote, San Juan in Vera Paz, Senahu {Champion). 



Much narrower' and less ovate than M. lesueuri, to which by its black legs this 

 species is analogous. The colour is a brilliant and deep blood-red. The head and 

 thorax are distinctly and rather sparingly punctured ; the latter is almost twice as wide 

 as long, the sides narrowing from the base. Scutellum smooth. Elytra with the striae 

 deeper and not so regular and with larger punctures than in M. lesueuri, and narrowing 

 at once from the base to the apex. Underside very smooth; the episterna and sides of 

 the breast black, the former quite smooth. Legs black, the tarsi rufous. Antennae 

 black, with five joints at the base red. 



34. Mycotretus hirudo. 



Oblongus, subparallelus, saturate sanguineus, antennis pedibusque nigris ; capite crebre, prothorace parcius 

 distincte punctatis ; elytris leviter punctato-striatis, interstitiis subtilissime vix visibiliter punctatis ; 

 corpore subtus lsevi. Long. 6 millim. 



Hab. Guatemala, San Geronimo {Champion). 



Very closely allied to M. cruentus, but differing from it in the following respects : — 

 the thorax is more sparsely punctulate; the antennae are wholly black, with the 

 exception that the second joint is pitchy-red; the tarsi are black; the striae of the 

 elytra have more numerous and finer punctures ; and the underside of the body is 

 wholly red. 



It is at the same time rather a narrower and more parallel insect. In the single 

 specimen received the elytra have a discoloured blackish tinge towards their apex.
