having the margin of tlie clypeus producetl in a lobe back- 

 ward over the eyes, so as to divide a portion of them. 



It is very probable that all the following species have been 

 introduced into England with corn and flour from foreign 

 countries ; the two first, however, appear to be naturalized, 

 and the others are occasionally found alive in bake-oflfices. 



1. U. Mauritanica Fab. Ent. Syst. 1. 113. 15. 



Length 3 lines. Shining piceous, minutely punctured all 

 over: mouth, antennae, legs, underside, margin of clypeus, 

 anterior angles of thorax and apex of elytra castaneous : head 

 with a transverse impression at the base of the clypeus : thorax 

 scarcely so broad as the elytra and narrowed anteriorly : elytra 

 with 9 punctured strise on each, the sutui'al one abbreviated. 



This insect is larger than the next, and not so thickly punc- 

 tured; the striae are deeper, the thorax is gradually nar- 

 rowed before, and the anterior angles are castaneous. It is a 

 native of the Caribbee Islands, and I have received several 

 from Senegal. Dr. Stephenson used to find it abundantly in 

 October amongst ashes in London, and one was taken out of 

 a dead cricket; and I have a specimen found in Copenhagen- 

 fields, where this or the next species is not uncommonly taken 

 under the turf. 



2. U. Fagi Panz.—Curt. Brit. Ent. pi. 363. 



For living specimens of this insect, as well as the larvae, 

 which resemble those of Tenebrio (pi. 331), I am indebted to 

 William Longman, Esq., who took them in great plenty in 

 the month of May, at the back of a baker's shop in Pater- 

 noster Row, where the pavement had been taken up. 



3. U. cornuta Fab. Ent. Syst. 1. 112. 13. — Lat. Gen. Cms. 



pi. 10. f. 4 & 5. 



Length 2 lines. Linear ferruginous, minutely punctured : 

 eyes black. Male with the mandibles forming two porrected 

 horns in front of the head, recurved and acute ; two teeth on 

 the crown of the head near the base ; margin of the clypeus 

 dilated: thorax somewhat lunulate-quadrate : elytra with 10 

 punctured striae on each, the 1st abbreviated. 



A native of Portugal. Living specimens have been found 

 by Mr. Sparshall in some ears of the Maize, that was grown 

 I believe near Norwich ; and Mr. Cooper has frequently de- 

 tected it in his bread in London. 



4. U. Iseviuscula Wilk. Mss.—Curt. Guide 254. 2. 



Length 1^ line. Ferruginous ochre, shining, minutely 

 punctured: eyes black: mandibles forming 2 porrected and 

 incurved horns, with 2 tubercles at the base of the head and 

 a deep channel across the crown : thorax subquadrate : elytra 

 with 10 punctured striae on each, the 1st abbreviated. 



From the Cabinet of the late Mr. Honey : the specimens 

 were taken in London. 



The plant is HeIleborHs/(vtidt{s (BQav's-fooi). Communicated 

 by the Rev. Professor Henslow.
