lateral apical margin ; the usual setiferous puncture exists, 

 however, near its normal position in the tjpical group of the 

 genus, i. e. where the curved apex of the recurved striole 

 should be. 



Tachyta microscopica, Bates, from Japan, agree j in all 

 essential points of structure with T. atoiaarius, and is scarcely 

 more than a geogi-aphical variety of the same. T. livida, 

 Bates, an Australian species, is a more distinct species of 

 the same group.

Differs from T. hioculatas and allies by the relatively small 

 and narrow thorax, the basal furrow of which is crenulated and 

 interrupted in the middle, as in the allied species. In all the 

 numerous examples the antenna and palpi as well as the 

 legs are of a clear honey-yellow colour. Tlie antennas are 

 long and slender and the joints two to five are nearly equal 

 in length. There is no trace of a thii*d elytral stria, and the 

 two discoidal punctures are very conspicuous. 



Tachys peryphinus. 



Paullo magis oblongus et minus convexus, aeneseenti-niger ; elytris
