rather fine and closely punctured striae, and smooth interstices. The sides of the meta- 

 sternum are distinctly punctured. 

 One specimen. 



42. Mycotretus incarnatus, 



Oblongus, parum ovatus, lsete sanguineus; capite prothoraceque parce sat profunde punctatis ; antennis nigris, 

 articulis quinque basalibas flavis ; subtus lsevis ; scutello haud punctulato. Long. 5 millim. 



Hab. Mexico, Jalapa (Edge) ; Guatemala, Panima in Vera Paz (Champion) ; Nica- 

 ragua, Chontales (Belt) ; Panama, Bugaba, Volcan de Chiriqui (Champion). 



This species is smaller than M. consanguineus or M. hamtaticus ; it differs from the 

 former in having five joints at the base of the antennae yellow, as well as in the 

 wholly impunctate underside. The head is more finely and more thickly punctured 

 than the thorax; the antennae are about as long as the head and thorax, their 

 third joint rather longer than the following two joints united; the palpi are not 

 especially widened, i. e. not as in M. noterinus. The thorax is transverse, but not 

 twice as wide as long ; it is not very much narrowed, in fact it only has the sides a 

 little turned in at the anterior angles. The elytra are striate, the striae with deep 

 punctures. Abdominal lines short and very indistinct ; metasternal lines quite distinct. 



About a dozen examples in all are referable to this species. 



43. Mycotretus rubidus. 



M. incarnato summa affinitate, magis ovatus, antennis brevioribus. Oblongo-ovatus, saturate rufus vel 

 sanguineus ; capite protboraceque parce distincte punctatis, elytris fortius punctato-striatis ; antennis 

 articulo tertio duobus sequentibus longiore, bis brevibus, articulis sex ultimis nigris. Long. 5|- millim. 



Hab. Guatemala, Chacoj, Panzos (Champion). 



So like M. incarnatus as to be with difficulty distinguished from it at first sight. 

 It is, however, more convex and more oval, not having the sides so parallel in the basal 

 half of the elytra. The antennae are distinctly shorter ; the fourth and fifth joints are 

 especially shorter (being distinctly elongate in M. incarnatus, while in this species these 

 joints are hardly longer than wide) ; the fifth joint is often infuscate ; and the sixth and 

 seventh joints are very short, and like the club are black. The episterna are very 

 obsoletely punctured. 



One of the specimens from Chacoj is of a ferruginous-red ; but all the red species 

 vary in the intensity of the red colour, though some never attain the sanguineous hue. 

 The three specimens received were captured in the Polochic valley.
