I'tilddiutvl;! e 1 a t e r i 11 a , //////. — One specimen of tlie perfect inso(;t, 

 and many ]»up;x>, toj^etliov with one larva, were taken by my,selt'. They 

 were all found in one loj^-, which was rather moist and rotten, its texture 

 being so destroyed that it was impossible to distinguish the species, though 

 it was probably Oak. The pupa> were concealed by a thin layer of the 

 wood, and were on the side adjacent the earth. The identity of the pu- 

 pa^ was established by raising several, and by means of the cast larva skin 

 which adhered to a pujia, T was enable to identify the larva. 



Sinoxylon A short time since I received from Mr. George 



Newman some fragments of a rustic ornament made from branches of 

 trees To all appearances there was nothing wa-ong, though on breaking 

 the pieces, they were found to be completely riddled by this insect. Its 

 borings were in a very fine powder. The time re(|uired for its transfor- 

 mations, has not been observed. 



The specimens raised by me were referred to l^r. Leconte, who is of 

 the opinion, that this insect is undescribed, should further investigation 

 prove it to be a native species. 



Sinoxylon basil are. Sa^. — Inhabits hickory wood in which it bores 

 to a considerable depth, preferring the hard central wood. Its borings 

 are very fine, and firmly compressed. No special preparation appears to 

 be made when about to assume the pupa state. After full development 

 is attained, it turns almost at a right angle and emerges through a circu- 

 lar opening in the bark of the hickoi-y. The transformation from the 

 larva tlivough the pupa into the perfect state is made in a very short space 

 of time. 



Anobium p a n i c e um , Fahr. — The larva of this insect is the great 

 destroyer of almost every root or seed used by man. It is known to the 

 druggist as the "' worm, " and it spares nothing in its ravages, the nour- 

 ishing oatmeal, the bitter Columbo and Gentian, and the poisonous Nux 

 Vomica, suffer alike. It has been known to perforate sheet lead. 



I have lately taken it in considerable abundance boring between sheets 

 of cork, such as are used for cabinets, in which situation it makes tortu- 

 ous canals, ruining the cork almost entirely. 



It remains in pupa about four or five days. 



Clytus e r y th r oc e ph al us, Oh'r. — This insect I raised from the 

 logs with the Sino.ii/loti hnsUavf. Its borings are much coarser, and its 

 preference is for the softer portions of the wood. Its course outwardly 

 after having assumed the perfect state is gradual, and not at a right an- 

 gle, as is the case with the Sinnxi/Ion.
