Onthocharis Batesii, sp. n. 



Oblonga, nitida, testaceo-rufa, capite pectoreque nigris viridi-tinctis, 

 elytris rufo-piceis basi nigro-picea vel toto nigro-piceis ; capite 

 subtiliter punctulato, clypeo subtilius punctulato, antice leviter 

 emarginato, medio bidentato ; thorace subtilissime punctulato, fere 

 laevi, linea impressa nulla ; elytris sat brevibus, evidenter striatis, 

 obsolete punctatis, interstitiis vix convexis, sicut laevibus ; pygidio

Hah. Amazons, Ega and Fonteboa {H. W. Bates). 

 This is a very distinct, short oblong species. The amount 

 of dark colour on the elytra and legs varies considerably.

Elongato-oblonga, rufo-picea, nitida ; capite laevi, vertice subtilissime 

 punctulato ; thorace subtiliter punctulato ; elytris distincte stria- 

 tis, striis obsolete punctatis, fere laevibus, interstitiis la>vissime 

 convexis, parce obsolete punctulatis, fere laevibus ; pygidio bene 

 convexo, laevi ; tibiis posticis angustis, dimidio apicali fere paral- 

 lels, tarsorum articulo basali latitudine duplo longiori. (PI. XL

Hab. Cayenne [Lacordaire). 



The above description is taken from Dejean's specimen of 

 11 0. myrmidon, Lacordaire," and is labelled " Cayennce, La- 

 cordaire." It is quite distinct from 0. myrmidon, Westw. 

 It is rather more depressed than most of its allies, the ante- 

 rior tibiae have all three teeth beyond the middle of the tibiae 

 acute, with the apical one very obliquely directed forwards. 



Onthocharis intermedia, sp. n. 



Elongato-oblonga, nitida ; capite virescenti, fere laevi, clypeo sub- 

 tilissime obsolete punctulato, antice piceo, medio emarginato biden- 

 tato ; thorace obscure virescenti, subtilissime latera versus dis- 

 tinctius punctulato, linea mediana brevi leviter impressa ; elytris 

 basi apiceque sat angustatis, virescenti-nigris, evidenter striatis, 

 striis sat crebre punctatis, interstitiis vix convexis, fere laevibus, 

 lateribus arcuatis ; pygidio virescenti, sat crebre evidenter punc- 

 tate ; corpore subtus nigro-piceo, pectore virescenti ; pedibus 

 piceis viridi-tinctis, tibiis posticis sat elongatis, basi angulatim sat
