CURCULIONID^. 185 



This same character will also distinguish it from 0. tenehricosus, Herbst., 

 and it is, moreover, a very much smaller insect. As Mr. Champion 

 remarks in his note on the insect, it seems an extraordinary thing that 

 so conspicuous an insect has not before been noticed, especially as it 

 seems to be far from uncommon. Mr. W. E. Sharp has discovered 

 that the food plant of this species is Cai'dutos arvensis (Ent. Mo. Mag. 

 1910, p. 33). 



TRACHYPHLCEUS, Germar. 

 In the Ent. Mo. Mag. for February 1909, p. 33 (Vol. xlv., 2 Ser. 

 XX.), Mr. Newbery points out further characters for separating 

 T. aristatus, Gyll., and T. olivieri, Bedel (= squamulatus, 01.). 



I. Scape of antennae nearly straight, 



gradually dilated to apex ; eyes 



larger and less prominent . T. aristatus, Gi/ll. 



II. Scape of antennfe angled out- 



wards about the middle, and 

 rather strongly dilated from 

 the angle to apex ; eyes smaller 



and more prominent . . T, olivieri , Bedel ( = squamulatnSy 



01.) nee Herbst. 



Bedel (Faun. Col. Bass. Seine, vi. 41) says that he substitutes the 

 name of olivieriiov sqitamidatus, heca,use Olivier refers to Cure, squamu- 

 latus, Herbst., which is plainly a difl'erent species and is probably 

 synonymous with T. scahricidu,s, L. 



BARYPEITHES, Duval.* 

 B, pyrenseus, Seidlitz (Die Otiorhynchiden, p, 73 (1868)) 

 The a:uthor of this species considered it to be only a variety of B. aranei 

 formis, Schrank. == 6rzmw (joes, 01., but it is a good species, and may easily 

 be separated by its more elongate shape, and different punctuation and 

 pubescence. Mr. Champion (Ent. Mo. Mag. xxxiii. (2 Ser. viii.) 1897, 

 134) points out the differences of the two species as follows : 



Rostrum in the male strongly, in the 

 female feebly, sinuated at the apex ; 

 thorax with very coarse, deep, 

 scattered punctures ; elytra convex 

 in the male, a little flattened on 

 the disc in the female, coarsely 

 seriate-punctate, the punctures 

 not very closely placed, becoming 

 much finer and shallower towards 

 the apex, and placed in shallow
