HENTZ TO HARRIS. 



Chapel Hill, N. C, Jan., 1829. 



When I come to examine my Tapheicerus No. 133 ? with 

 No. 133, I wonder how I could have supposed them to be the 

 same species, but when I made my catalogue I had but little 

 leisure. Your description marked No. 1 [in letter of Dec. 19, 

 1828], does not quite seem to correspond with 133, which is 

 nearly }y^ inch, and has silver white scales on the elytra that 

 become yellowish, however, near the base and golden on the 

 thorax and head. The thorax I would de- 

 scribe by saying that it has two elevated 

 ridges rather than that it has three grooves, 

 because, although there are indeed three de- 

 pressions, the ridges do not quite reach the 

 base, and they have a widening space at 

 base between them. The mentum, as in 

 yours, is very much produced. This, the 

 outline of the insect, though roughly made 

 with the pen, will give you an idea of the 



Fig. 8.
