Notes on the food-habits of some N. A. Rhynchophora. 
BY E. A. SCHWARZ. 
Panscopus ertnaceus Say, occurred abundantly last July in the 
mountainous regions of Virginia on wild Grape-vines, feeding on the 
foliage and young buds. 
Eudiagogus. The food-plants of our two species are the Coffee— 
weeds (Cassia occidentalis and C. obtusifolia, and probably also other 
species of this genus). /. pulcher is much more abundant and more 
widely distributed than Rosenschoeldt and sometimes defoliates large 
tracts of these troublesome weeds. 
Pachytychius discoideus Lec., breeds in the flower heads of Hedlentum 
tenurfolium. es 
Anthonomus gularis Lec.; oviposits in the blossoms of Cuassia.mari- 
landica in the middle of August, the larve developing in the pods of 
the plant. 
Anthonomus flvicor ms Boh. I found this inquilinous in a globular 
Acarid gall on the leaves of Solanum eleagnifolium at Columbus, Texas. 
Rhyssematus lineaticollis Say. Larve and pupz were found. in the 
seed pods of Asclepias tuberosa at Detroit, Mich., toward the end of 
August. Thereare usually only two or three, rarely more, larvee within 
the same pod, and they destroy only a small portion of the seeds. 
-Himatium errans Lec., is inquilinous in the galleries of Tomicus 
cacographus under bark of Yellow Pine. It occurred abundantly at 
Tallahassee, Fla., in April. " 
Hypothenemus eruditus Westw. (hispidulus Lec.), infests not only dry 
twigs of all sorts of deciduous trees, shrubs and woody plants, but also 
old cotton bolls, dried up figs, pomegranates and other fruits. In con- 
sequence, of this diversity in food-habits the beetle exhibits considerable 
variation in size, shape and sculpture. I have seen specimens from the 
Bahama Islands, Jamaica and Brazil. Not rarely specimens occur in 
which the head is protruded and thus apparently not covered by the pro- 
thorax. Upon such specimens Mr. Eichhoff seems to have established 
his genus Szephanoderes. 
Micracis rudis Lec., bores under the bare of the larger twigs of 
Hackberry (Cv/#s). It is.a rare species and I always found only single 
specimens. Occurs in Michigan, Texas and Georgia. 
Micracis opacicollis Lec. . Very abundant at Washington, D. C., in 
small oak twigs which have been affected by a Cynipidous stem-gall.
