to be quite as abundantly represented within the tropics as with- 

 out. Nothing but their smallness has hitherto prevented their 

 discovery.

The insect is of a bronze colour, a purple reflexion appearing 

 on the back in irregular patches as the light may fall upon it. 

 The palpi and the base of the antennre are of a yellowish colour ; 

 the apex of the third joint of the maxillary palpi, however, as 

 well as that of the second, third, and fourth antennal joints, is 

 brown, of which colour is also the remaining part of the antennse. 

 The second antennal joint is the shortest, the third and fourth 

 are rather longer than the following. The mandibles are rather 

 straight and porrected. The sides of the thorax are almost an- 

 gular, and furnished with a setigerous puncture at the broadest 

 part ; that is, just before the middle. There are seven distinct 

 rows of punctures on either elytron, and an accessory one along 

 the side of the scutellum, the rows decreasing in length towards 

 the margin and the punctures in depth towards the apex, the 

 first row on either side, however, changing before the apex into 

 a furrow which falls in with that which separates the margin 

 from the rest of the elytron. Before and beyond the middle, 

 in the region of the third row of punctures, is an excavation 

 containing a puncture which is situated upon the third inter- 

 stice. The excavation nearest the base is the deepest. The apex 

 of the elytra is marked with a spot of dirty yellowish colour, 

 prolonged on either side along the margin, which is here rather 

 broad. 



If my memory serves me right, the insect resembles the 

 Tachyjjus JIavipcs.
