JIYCOTRETUS. / 7 



Mycotretus dorsonotatus. 



M ijcoircXus dorsonotattts, Lac. Erot. 151. 



Cayenne, Ega, St Paulo (Bates). 



The punctuation is very curious, being frequently gemellate on 

 tlio elytra, the interstices elevated. The scutclluni and a small 

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

 Ventral segments and sides of metasternum deeply })unctured. 



Mycotretus durius, 



Mycotretus durius, Lac. Erot. IGl. 



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 spots on tlie alternate 

 interstices: antennas with the 8tli joint conspicuously dilated.

Oblongus, sub parallelus, nitidus, la^te fulvus, elytris ochraceis, 

 fintennis clava punctoque verticali nigris, thorace subtransverso, 

 lateribus rectis, margiiie antico infuscato, punctis 3 discoidalibus 

 nigris, i>arce ]>unctato; scutello nigro, punctulato; el^^tris tenuo 

 punctato-striatis, interstitiis vix punctulatis; corj)ore subtus la)\i. 

 L. 31 Hn. 



Ega (Bates). 



In my specimen tlie elytra are slightly infuscato with a pale 

 nnrrow band before the middle, but tiiis I think probably acci- 

 dental.

Head and thorax sparingly, visibly punctate, elytra rather 

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