 Remarks on the Habits of some species of Cleridae. 



BY FRANK H. CHITTENDEN. 



Elasmoccrus tenninahis Say. — Last year at Staten Island, May 

 17th, I discox'ered in an infested grape vine a larva of Phyinaiodes 

 aintcnus, to which was attached another larva engaged in devouring 

 it by absorbing its juices. The predaceous larva had begun opera- 

 tions at the caudal extremity of the Cerambycid, about one-quarter 

 of which was shriveled up. The remainder was intact, and the in- 

 sect was still alive when placed in alcohol two days later. A pupa 

 found at the same time was almost entirely white, greatly resembling 

 a hymenopterous pupa. On the i8th it had begun to color, the 

 elytra assuming a darker hue, and on the following day the species 

 was recognizable. 



Trichodes apivonis Germ. — I ha\-e found on the flowers of 

 Solidago and the New Jersey tea plant (Ceanothus americanus) during 

 July and August. Ithaca, N. V. 



Clems rosmarits Say. — A specimen was observed last year 

 seated on the leaf of a shrub devouring a small Nitidulid, Cerciis 

 abdominalis. Orange, N. J., June 9th. 



Thanasimzis dubius Fab. is probably restricted, at least in its 

 adolescent stages, to the Coniferae. It appears early in the Spring 

 and preys upon pine-boring Scolytidae. 



Clems thoracicus Oliv. is quite common in this \'icinity, occur- 

 ring on a variety of deciduous trees during May and June. I have 

 bred specimens from the following: Pear tree February nth and 

 March 2d; Butternut, March i8th; Chestnut, May ist to 14th; 

 Willow, April 8th. This species is undoubtedly predaceous, and I 

 suspect lives at the expense of various Cerambycid larvae. One 

 specimen reared from a Chestnut twig, attacked and made a meal 

 off the abdomen of an Anthaxia, which had bred from the same 

 wood. 



Unfortunately, I have not preserved good specimens of the 

 larvae. Full grown specimens are about a quarter of an mch in 

 length, of a nearly uniform purplish hue, hairy, and the thorax is 

 ornamented by two dark spots. The last segment terminates in two 

 corneous appendages of a dark brown color. 



When full grown the larva forms a burrow, often in the disused 

 gallery of some Longicorn, or other wood borer, lining it with a 

 silvery silken substance. One of these burrows in my possession 

 measures 80 mm. in length and 2-3 mm. in diameter.
