308 THE ENTOMOLOGIST. 



5. B. Cerasorura, Herhst. Ferruginous, beneath paler; 

 elytra variegated with paler spots : length 2 — 3 lines. This 

 species reproduces the coloration of B. Nucum. 



c. Femora with no tooth. 



6. B. rubidus, Gyll. Not unlike the preceding, but more 

 uniform in colour, and with the thorax and under surface 

 more or less black ; the rostrum nearly alike in both sexes, 

 &c. : length 2 — ^^ lines. Commoner than the preceding, 

 with which it is often confounded. 



Group II. — Small black species, with the pygidium nearly 



covered. 



7. B. Crux, Fah. — Black; elytra with a white cross : length 

 1 line. One specimen in Leach's collection, with a label in 

 his own writing. 



8. B. Brassicae, Fah. Black ; scutellum and body beneath 

 white ; elytra with a fine gray pubescence ; antennae brown : 

 length \^ — 2 lines. Common. 



9. B. pyrrhoceras, Marsh. Exactly like the preceding, 

 but the rostrum is nearly alike in both sexes, and the antennae 

 are entirely pale, except the club : length 1 — If line. Less 

 common than the preceding. ^ 



Anthonomus. 



Group I. — Elytra with paler fasciae and markings. 



A. Anterior femora with a large triangular tooth. 

 L A. Ulmi, DeG. Ferruginous ; rostrum elongate, sub- 

 opaque ; elytra punctale-slriate, with the punctures sub- 

 quadrate, and with a ])osterior transverse whitish fascia: 

 length 2 — 2^ lines. 



2. A. C\\e\xo\di\\\, Desh. Like the preceding in coloration, 

 but at once distinguished by its very convex thorax and the 

 smooth interstices of the elytra: length 1^ — 2 lines. Rare: 

 taken formerly by Mr. E. W. Janson near London, 



3. A. ruCus, Schh. Again very like A. Ulmi in coloration, but 

 to be recognized by the shining very cylindric rostrum ; the 

 interstices of the elytra are smooth and shining : length 

 Ij — 2 lines. Recorded as British by M. Desbrochers de 

 Loges. 



(A fourth species, A. Pyri, Schh., is much darker than the 

 preceding, with a very long rostrum, and the elytra are 

 bituberculate at the base.)
