62 MYCOTRETUS. 



Mycotretiis ir^aculatus, 



■ Erotylus macidatus, OJu\ Enc. Mcth. vi. 43G (1791). 

 Mycotretus ? maculatus, Lac. Erot. 192. 



Jiguratus, Lac. Erot. 159. 



Cayenne, Columbia, Para (Bates). 



Interstices of elytra very sparingly punctured ; coxal lines 

 present. Antennae with a 4 -jointed club, joints short, adpressed. 



Mycotretus miitabilisj sp. n. 



M. maculato simillimus, sed latior, colore rufo-fulvo, thorace- 

 que brevicre distinctus. L. 4 lin. 



Ega Para (Bates). 



This is very close to M. ■riiaculafjis, but is I think distinct ; the 

 markings on the thorax are the same, exce^^t that the basal pair are 

 much more obli<jiie ; the variations are numerous, the apical pair 

 united, the basal pair united into a triangular spot, the discoidal 

 one absent, &c. In the elytra the basal fascia is never divided 

 as in M. maculatns, but sometimes reaches the base, though not 

 the external margin. In one specimen (J/, tricinctus), which 

 may be distinct, there is a third sup|)lementary subapical fascia. 

 Sides of the metasternuru very s['arlngiy punctate.
