 Mycotretus dorsonotatus. 



Mycotretus dorsonotatits, Lac. Erot. 151. 



Cayenne, Ega, St Paulo (Bates). 



The punctuation is very curious, being frequently gemell ate on 

 the elytra, the interstices elevated. The scutelluni and a small 

 dot on the anterior and posterior margin of the thorax black. 

 Ventral segments and sides of metasternum deeply punctured. 



Mycotretus durius. 



Mycotretus durius, Lac. Erot. 161. 



Cayenne, Ega (Bates), Upper Amazon. 



The palpi are somewhat dilated, but the peculiar punctuation 

 evidently approximates this species to M. dorsonotatus. Lacor- 

 daire's type is nearly unicolorous, but my specimens have the 

 elytra with four rows of quadrate brown scoots on the alternate 

 interstices: antennae with the 8tli joint conspicuously dilated. 



Mycotretus parallelus, sp. n. 



Oblongus, subparallelus, nitidus, Isete fulvus, elytris ochraceis, 

 antennis clava punctoque verticali nigris, thorace svibtransverso, 

 lateribus rectis, margiue antico infuscato, punctis 3 discoidalibus 

 nigris, parce punctato; scutello nigro, punctulato; elytris tenue 

 punctato-striatis, interstitiis vix punctulatis; corpore subtus Isevi. 

 L. 3| lin. 



Ega (Bates). 



In my specimen the elytra are slightly infuscate with a pale 

 narrow band before the middle, but this I think probably acci- 

 dental. 



Mycotretus graniformis.* 



Mycotretus graniformis, Lac. Erot. 152. 



Cayenne. 



Head and thorax sparingly, visibly punctate, elytra rather 

 deeply punctate- striate, interstices very finely punctvdate; under- 

 side shining, faintly punctate,
