HARRIS TO HENTZ. 



MILTON, Nov. 19, 1828. 



Your dissertation on the culture of silk came safely to hand, 

 and after reading the papers I sent them to my friend, I. M. 

 Gourgas, a German by birth, who is zealously engaged in pro- 

 moting this pursuit. My honored mother has raised silk 

 worms for more than ten years, and supplied herself with all 

 her sewing-silk from their labors. On my fathers place are 

 many of the white mulberry trees, which are found to produce 

 the best silk. Mrs. Harris never raises but one crop in a year. 



Having been repeatedly called upon for entomological com- 

 munications in the "New England Farmer," I have concluded 

 to publish in it some of my manuscript descriptions, with the ad- 

 dition of popular remarks. Several numbers have been printed, 

 which I send you as a sample. The next communication contains 

 eleven new Dyticidee. This will be followed by some of the 

 Elateridce, including two new subgenera of my own, viz. : No- 

 thora, containing the species with pectinated nails ; and TapJiei- 

 cerus, in which the suture between the ora and antcpectus is 

 dilated to receive and bury the antenna. In this subgenus the 

 antennae are very short, the thorax is gibbous, and the body 

 is very much covered with scales, or short, flattish bristles; 

 though nearly related, it differs from Eucnemis Ahr. and 

 Mann., in which the mouth is entirely retracted, the antennas 

 very much approximated at base, the prosternum very short, so 

 that the power of leaping is weak ; and the posterior COXSB very 

 much dilated, so as to conceal the greater part of the thighs. 



I am aware that the "New England Farmer" is not likely 

 to be much circulated among men of science, and therefore 

 will not be considered the best authority ; but it is a conven- 

 ient, vehicle at present ; and, such is the ambition of European 

 entomologists to anticipate Americans, that I willingly yield to 

 the solicitations of several friends in publishing what may pos-
