labelled by Wollaston himself " C. niqroterminatus (= mixtm, Muls.)." 

 This example I have carefully compared with the Madeiran types (2) 

 in the British Museum, and my remark that C. nigroterminatus, Woll., 

 is " probably distinct from C. mixtus, Muls. and Key," proves to be 

 correct. The Newton Abbot insect agrees perfectly with specimens 

 of C. mixtus (one of which was sent me by M. Bedel) from Spain and 

 Algeria in my collection, and it differs as follows fi'om the Madeiran G. 

 nigroferminatus : — The lateral tubercles of the thorax are obtuse 

 (instead of acute) ; the scattered whitish scales on the elytra are 

 much smaller and more evenly distributed (not forming a well- 

 defined patch along the suture behind the scutellum, as in G. nigro- 

 terininatus) ; and the tarsi are a little darker, (instead of clear 

 rufo-testaceous, with the exception of the tip of the apical joint). 

 The Newton Abbot specimen has perhaps not been recorded ; Crotch, 

 however (Entom. ii, p. 260), mentions two British examples — one found 

 by Wollaston at Gainsborough and one in Dr. Power's collection, — 

 an,d to judge from his remarks Wollaston seems to have noticed the 

 less tessellate appearance of the elytra in the British insect. Follow- 

 ing M. Bedel and myself the two species must be quoted thus : — 



1. nigroterminatiis, Woll. — Madeira. 



Grotchi, Ch. Bris. —Madeira (not England). 



2. mixtus, Muls. and Ee\'' — England, France, Spain, Algeria. 



My note has been criticized by Herr A. Schultze, of Detmold, in 

 the Deutsche ent. Zeitschrift, 1894, p. 434. It is quite evident from 

 his remarks that neither he nor Ch. Brisout had examined Madeiran 

 specimens of G. nigroferminatus, and that they have had G. mixtus 

 only before them.
