Description and History of a New Species of Erirhintjs, 

 E. juniperinus. By Francis G. Sanborn. 



Reddish testaceous, covered with short fulvous pubescence ; head, 

 rostrum, club of antenna and abdomen beneath, except apical seg- 

 ments, dark brown. A slight longitudinal impression between the 

 eyes, which are prominent and coarsely granulate. Prothorax dis- 

 tinctly punctured, slightly broader than long. Elytra with deeply 

 punctured longitudinal fuiTows, a curved semi-fascia behind the middle, 

 convex before and narrowest at suture, extending from the sutural to 

 the fifth interstitial Une, dark chestnut and almost devoid of pubes- 

 cence (this marking, viewed as a common spot, resembles an arrow- 

 head of obtuse angle, directed toward the apex of the elytra) ; scutel- 

 lum and vicinity, suture and external margins of elytra frequently 

 deeper in color. Length from tip of rostrum .12 to .15 in., rostrum 

 .04 in. Twenty-eight specimens examined. 



This little weevU is frequently found in Eastern Massachusetts dur- 

 ing the month of May, depositing its eggs in the beautiful epiphytous 

 fungus, Podisoma juniperina, upon the succulent flesh of which its 

 larvae feed in numbers, and within which it undergoes its trans- 

 formations. I have reared the imago in April fi-om the dried fungi 

 collected the previous October. Its habits remind one of those of the 

 plum-weevil, Conotrachelus nenuphar Herbst, which frequently uses 

 the Sphceria morbosa as a nidus.
