Tylodes is distinguished from Cryptorhynchus by the ab- 

 sence of a scutelliim. It was establislied as a genus by 

 SchonheiT in his " Curculionidurn Dispositio Methodica," 

 where he characterizes Acalles as a subgenus, which he says 

 differs from the former one in the structure of the antennae and 

 elytra, and the canal beneath the thorax is more abbre- 

 viated. Not seeing the utiHty of giving names to sections so 

 slightly different in structure, I adopted in my Guide the name 

 of Tylodes, and A. lloboris very much resembling C. Lapatlii 

 in form, I included them in the same genus. 

 The following are British species of Acalles : 



1. Ptinoides Marsh, p. 258. 59. 



Length 1^ line. Pitchy-castaneous, rugose with large 



punctures, partially filled with ochreous and somewhat 



erected scales, forming 4 indistinct lines on the thorax : 



rostrum, antennae and tarsi castaneous or ferruginous : 



elytra deeply striated, with little foveae, ochreous with 



scales, excepting a fascia across the middle, 2nd and 4th 



striae elevated, with 2 oblong black tufts of scales on each : 



base and a band at the middle of the thighs and tibias 



clothed with ochreous or whitish scales. 



Not uncommon in Norfolk on nettles in hedges in May. 



Mr. Dale has taken it in June and the beginning of October 



at Barton Cliff, Hants, and at Maiden Castle near Dorchester, 



and Mr. Dillwyn near Swansea. 



2. Roboris Curt. Brit. Ent. pi. 550 ? . 



The natural size of the female is pretty nearly given below 

 the magnified figure, but the male is smaller. I took a pair of 

 this curious and rare insect off an Oak-tree in Suffolk the be- 

 ginning of June many years since. 



3. globulus Herhst C. 6. 398. 376. tab. 91./ 7. 



*' Black, somewhat opake, dorsal line and sides of breast 

 with white scales, elytra globose, deeply sulcated and 

 punctured, interstices narrow and crenated." Gi/IL 3. 

 235. 138. 

 He says it lives in the young shoots of the Trembling Pop- 

 lar. 



Mr. Stephens has called it Rutidosoma and Schbnherr pro- 

 bably will give it another name. 



For the rare and beautiful Lobelia nrens (Acrid Lobelia) I 

 am indebted to B. R. Morris, Esq., who found it near Ax- 

 minster.
