260 THE CANADIAN ENTOMOLOGIST. 



Ampeloglypter sesostris makes a gall on the grape vine, as also does A. 

 ater. (Riley, BuU. Bklyn. Ent. Soc, VI., p. 6i.) 



Ce?ttrmus scutellum-album I found on the flower heads of the daisy. 



Balaninus qiiercus, B. nasicus, B. uniformis were bred from different 

 kinds of acorns. B. obtusus inhabits hazelnuts. B. caryce lives in hickory 

 nuts. B. proboscideus and B. rectus were bred from chestnuts. The 

 latter also inhabits acorns. (Hamilton, Can. Ent., 22, p. 1-6). 



Cylas formicarius bores in the roots of the sweet potato in Florida. 

 (Comstock Rep. Dept. Agricul., p. 250, 1879.) 



Eupsalis minuta bores under the bark of oak, chestnut and maple. 



Rhyiichophorus cruentatus lives in the lower parts of the trunk and 

 roots of the palmetto. I have taken about one hundred individuals at 

 Enterprise, Florida, in May. The Specimens were caught boring in the 

 soft pulpy substance in the trunk of a young and freshly cut palmetto 

 tree. R. pabnarum also lives in the palmetto. 



Rhodobce?ius 13-punctatus I found on evening primrose ( CEnothera). 

 Probably lives in its larval stage also upon the plant. It also infests the 

 stems of Ambrosia, Xanthium strutnarium and thistle. 



Cactophagus validus has been found exclusively under decaying 

 Opuntia leaves, the larva no doubt living within the leaves or roots of 

 the same plant. (Insect Life, I., p. 199.) 



The genus Sphenophorus infests roots or lower parts of the stems of 

 various wild or cultivated Graminaceous plants (1. c). S. parvulus lives in 

 the roots of meadow grass ( Timothy), and S. robustus in the roots of maize 

 or corn, and S. ochreus in the roots of Scirpus atrovirens. 



Calandra granaria and C. oryzce. Both these species depredate 

 upon stored wheat, corn, rice and and other grains. 



The genera Yuccaborus and Scyphophorus infest plants of the genus 

 Yucca (I.e., p. 199). 



The genera Dryotribus, Gononotus, Macrancylus, Mesites (?), Elas- 

 soptes are strictly maritime, and live in larva and imago states in old 

 boards and roots, etc., washed up on the beach. (1. c, p. 198). 



Cosso?ius corticola I found in abundance under the bark of dead pine 

 trees. At Enterprise, Florida, C.piniphilus, C. concinnus and C. crenatus 

 9,lso live under pine bark. (Ricksecker, Ent. Am., I., p, 96).
