Genus CCCLXVI. — Hamaticherus, Megerle. 



Falpi with the terminal joint elongate-obconic, maxillary rather longer than the 

 labial. Antennw longer than the body, the five basal joints very robust, the 

 remainder becoming suddenly more and more attenuated to the apex, and 

 slightly compressed; second joint very short; the rest, except the apical one, 

 nodose at the apex : head rounded, nutant : eyes lunate : thorax rounded, 

 unequal, rugose, the lateral margins each with a single spine : elytra elongate, 

 convex, rugose : legs long : intermediate tihiw simple. 



This genus appears to be distinguished from Cerambyx by the 

 superior length of the antennae, and by having the body convex, 

 and the thorax transversely rugose, as well as by the dissimilarity 

 in the proportions of the labial and maxillary palpi to each other : — 

 I have my doubts whether the species of this genus are truly Bri- 

 tish ; but as both are found abundantly in France, and also in 

 Sweden, and in the intermediate countries, it is likely they may 

 be indigenous. 



J Sp. 1. Heros. Ohlongus, posteinus attenuatus, niger, elytris apice piceis suh- 

 spinosis, thorace rugose glabra, utrinque spinoso. (Long. corp. 1 unc. 6 — 8 hn.) 



Ce. Heros. Fabricius.—Ua. Heros. Steph. Catal. 196. No. 2017. 



Oblong, attenuated posteriorly, black; head with a deep channel : thorax irregu- 

 larly wrinkled transversely, with an acute spine on each side : elytra atte^ 

 niiated towards the apex, which is piceous, the inner angle with a minute 

 spine, the disc rugulose, with three very obsolete longitudinal lines: legs and 

 antennae black, the latter with the tibise and tarsi clothed with an ashy pile. 



A pair of this species are, I believe, in the collection at the 

 British Museum, which are said to have been captured in the west
