The pupa, like others of the family that have come under my 

 notice, does not exhibit the characteristic structural features of the 

 adult insect. One larva taken March loth had assumed the pupal 

 stage on the 23d, and became a perfect insect April 8th. 



Thaneroclerus sanguineus Say, has similar habits to the fore- 

 going. One specimen was found dormant in a burrow which it had 

 constructed in the dead wood of an Oak, March 27th; another was 

 taken from dead Maple wood. May 9th, both at Ithaca, N. Y. Two 

 examples were found by Mr. G. W. J. Angell at Rangeley Lakes, 

 Maine, May 20th, on a pile of cut Birch, one of them taken from 

 the wood. 



Hydnocera unifasciata Say. — Taken on Chestnut and Tulip trees 

 July 6th to 20th. 



H. humeralis Say. — Occurs in numbers on the common Bay 

 berry (Myrica cerifera) at the beaches in the vicinity of New York 

 City — Highland Beach, N. J., Rockaway Beach, L. I., June i8th 

 to July 3d. 



H. pallipennis Say. — Occurs with H. unifasdata, July 24th to 

 September 8th. 



H. verticalis Say. — Bred from Hickory twigs June 15th to 29th. 

 Occurs on Hickory leaves July 9th to 26th. 



H. longicollis Ziegl. — Bred from a larva found under the bark 

 of Witch-hazel (Hamamelis virginica). It was taken from the blind 

 end of a burrow that had been made by some beetle — presumably a 

 Cerambycid — of the size of Phywatodes vaj-iabilis, and was hemmed 

 in by a layer of castings about half an inch long. The burrow was 

 lined with a silvery substance somewhat like that observed in the 

 burrows of Cierns thoracicus. The larva when found, April 26th, 

 was about to pupate; it transformed in confinement May 22d. I 

 have also bred this species from Hickory twigs, and have found the 

 beetles on the leaves of Hickory in July. 



Phyllobcemis dislocatus Say. — Bred from Butternut twigs May 

 4th. Occurs in this vicinity in June. 



Chariessa pilosa Forst. — Bred from a larva found in a Hickory 

 twig at South Woodstock, Conn., on October 30th. Imago devel- 

 oped in May. Also taken at Ithaca, June 14th in copula on the 

 trunk of a Butternut tree. 



Laricohius erichsoni Rosen. — Abundant in early Spring on the 

 foliage of White Pines.
