57. Mycotretus hsemapterus. 



Oblongus, parum ovatus, saturate rufus, capite prothoraeeque nigris, ore et subtus rufescentibus, illo crebrius. 

 hoc parce leviterque punctatis ; elytris sanguineis ad apicem subinfuscatis, punctato-striatis ; antennarum 

 articulis quinque apicalibus nigris. Long. 3f-4 millim. 



Eab. Panama, Bugaba {Champion). — South Ameeica, Amazons (Bates). 



Bather narrow ; mouth, palpi, base of the antennae, and legs bright red, and nearly 

 of the same colour as the body beneath. Head and thorax shining black above, reddish 

 beneath, except at the sides the latter is more or less black. Elytra deep but bright 

 blood-red ; with small punctures in the series, which are fuscous beneath the epiderm 

 in one specimen. Scutellum red. There is no other similarly-coloured species of 

 Mycotretus yet described, except M. cercyonoides, which it a little resembles. Two 

 specimens from the Amazons in the Cambridge collection appear to be referable to the 

 same species. The maxillary palpi in our insect are of the moderately widened form ; 

 in the Amazons examples they seem to have the apical joint wider, and therefore, 

 though they are identical in colour, it must not be too hastily assumed that they belong 

 to the same species. 



Three specimens from Bugaba. 



58. Mycotretus fuscitarsis. (Tab. III. fig. 25.)

 Cahabon, Chacoj (Champion); Costa Eica (Van Patten); Panama, Bugaba, Volcan de 

 Chiriqui (Champion). 



The short, almost orbiculate, form separates this species and M. coccineus, Lac, and 

 M. sanguinosus, Crotch, from the other red species. The maxillary palpi have their 

 apical joint very wide. The sides of the metasternum and its episterna are alutaceous 

 and punctured, but rather obsoletely so. The interstices of the striae of the elytra are 

 thickly but finely punctured. M. fuscitarsis varies considerably in size ; the largest 

 specimens, which are from Cerro de Plumas, measure six millimetres in length ; others 

 from Chacoj and elsewhere are not more than four and a half millimetres. Some 

 specimens seem to have the interstitial punctuation deeper than others. We give a 

 figure of one of the large specimens from Cerro de Plumas. 



59. Mycotretus sanguinosus.

Extremely close to M. fuscitarsis ; although Crotch has placed sixty-four species 

 between them, they both belong to the section with much dilated maxillary palpi.
