of certain species of Willow. — Part 2nd. 2G5 



bred, June 2 and subsequently, numerous specimens of the same insect. 

 A pair sent to Mr. Ulke were pronounced by him to be S. concofor 

 Lee. j but as the insert agrees exactly with Say's, description of S. in- 

 omata, and as LeConte professes to be unacquainted with this last spe- 

 cies. [Say's Works II, p. 100), I believe concohr to be a mere syno- 

 nym. The most careful authors are sometimes liable to overlook spe- 

 cies which have been already described. Many years ago I pointed 

 out to Dr. LeConte that the Elater obesus of Say, which he had failed 

 to identify, | Say's Works II, p. 100.) was nothing but a pretty com- 

 mon species which, according to him, had been subsequently described 

 by Germar as Diacanthus acutipennis, and which now forms the type 

 of the new genus Oxygonus Lee. Here both Germar and LeConte 

 failed to identify a species, which Say had circumscribed by a very re- 

 markable character — the tooth on the middle of the tarsal ungues. 



INQUILINES. — Family Cryptophagid;e. 



Loberus impresstjs Lee. Bred a single specimen Sep. 12 from 

 the Cecidomyidous gall S. bra ssicoides Walsh. This insect is consider- 

 ed rare, but it occurs abundantly in Illinois in winter-gathered moss. 

 The genus must be carefully distinguished from another bearing the 

 same name iu TeUphoridx, I do not know which has the priority. 



Family MyCETOPHAGIDJE. 



LlTARGUS 4-SPILOTUS Lee. Bred a single specimen Aug. 30 from 

 the Acaridous (?) gall S. senigma Walsh. (See above page 227.) 



Family Curculionid^E. 



Anthonomus sycophanta, n. sp. — Brown-black. Head finely and rather 

 sparsely punctate, except on the vertex, and with short appressed white hairs. 

 A large impressed shallow puncture behind a line connecting the upper curve 

 of the eyes. Rostrum \ longer than the head and thorax together, curved in a 

 circular arc of about 4J°, finely punctate and rarely with its tip rufo-sanguine- 

 ous; antennae inserted 3-5ths of the way to its tip, rufous, the club obfuscated. 

 Thorax with close-set larger punctures and long appressed white hairs, so as to 

 appear opaque. Scutel rather longer than wide, generally white with appress- 

 ed hairs, sometimes blackish or rufous. Elytra \'i times as long as the head 

 and thorax together exclusive of the rostrum, punctate-striate with large punc- 

 tures, the. interstices with fine rather sparse punctures and white hairs, so that 

 the whole elytrum appears opaque; rufo-sanguineous, sometimes dark sanguine- 

 ous, rarely verging on to luteo-sanguineous, sometimes with a cloud round the 

 scutel and also the interior edges of the suture, brown-black. All beneath 

 tinged with white from short appressed white hairs. Legs dark rufo-sanguine- 

 ous, the knees and -onetimes the' entire leg, brown-black. Length exclusive 

 of the rostrum .OS — .12 inch.
