sed articuli sunt valde dissimiles, corpus minus est necnon pubes- 

 cens pallidum alatum (baud glabrum apterum), et caput sub pro- 

 noto omnino absconditur. Ab Orthopero (cui aliquo modo approxi- 

 mat) antennarum 11- (nee 9-) articulatarum structura, necnon 

 capite toto sub prothorace recondito, praeter caetera, differt. 



Microstagetus parvulus. 



M. ovali-obovatus, rufo-testaceus, sericeo-pubescens ; prothorace 

 nitidissimo, impunctato ; elytris nitidis, vix obscurioribus et (oculo 

 fortiter armato) minutissime ac levissime punctulatis; antennis 

 pedibusque vix pallidioribus. Long. corp. lin. vix |-.

 corp. lin. vix |-. 



Trichopteryx Wollastoni, Matth., loc. cit. i. 248 (1865). 



Habitat in Canaria, Teneriffa, Gomera et Hierro, sub quisquiliis, 

 praecipue per regiones sylvaticas intermedias, vulgatissima. 



The A. Wollastoni differs from the European A.fascicularis (which 

 it much resembles) in its rather smaller size and more parallel out-
