108 MADEIRAN COLEOPTERA. 
additional material, therefore, I am enabled to arrive at the following 
particulars : viz., that the species is larger and more brightly varie- 
gated than the description there given would imply,—the largest 
examples ranging to 44 lines in length; whilst the transverse post- 
medial patch of its elytra (although rather narrow) is bright and 
distinct : the legs also of its males are very much longer than those 
of any other Acalles here enumerated. Although I can scarcely 
imagine that I was mistaken in giving the vicinity of Funchal as the 
“habitat ” for the specimen described (for I believe that I captured 
it on the cliffs to the eastward of the town), it is evident that the 
insect belongs normally to a higher altitude, ascending to nearly 
6000 feet above the sea, 
303. Acalles coarctatus, n. sp. 
A. elongato-ovatus angustulus, squamis brunneis subflavescenti- 
busque variegatus ; prothorace transversim setoso-tuberculato, ad 
apicem valde bifasciculato-setoso ; scutello distincto ; elytris punc- 
tato-striatis, postice valdius productis coarctatis, carinis inter- 
ruptis nodulisque setosis (preesertim post medium) instructis, pone 
medium longe bifasciculato-setosis, ide ad apicem plaga hastata 
pallidiore ornatis. 
Long. corp. lin, 24-22. 
A, clongate-ovate, and densely variegated all over with brown and 
somewhat yellowish scales, ostvwm piceous, opake, and roughly 
punctured, in the males; rufo-piceous, shining, and less punc- 
tured in the females. Prothorax a good deal attenuated both before 
and behind, but rounded in the middle; with a broad but shallow 
dorsal channel, and with four setose tubercles across the central 
portion (the inner ones of which are the most evident); produced 
and very setose at the apex, where the sete arrange themselves 
into two distinct fascicles. Scutellum very apparent, and clothed 
with paler scales. Hlytra very much lengthened-out, and coarctate, 
behind ; likewise a good deal rounded-off, and narrowed, at the 
shoulders, where they are of exactly the same breadth as the base 
of the prothorax ; punctate-striated ; with the nodules and inter- 
rupted ridges tolerably developed (especially behind the middle) 
and very setose,—the two larger postmedial ones forming two 
very prominent, somewhat divaricate, setose fascicles, behind 
which there is a paler hastate patch extending quite to the apex. 
Antenne ferruginous. Legs very setose. 

A singular Acalles, readily known by its being more coarctate and 
produced behind than any of the other species here enumerated, by its 
prothorax and elytra being of precisely the same breadth at the point 
of union, by the dull yellowish-brown setee and scales with which it 
is clothed, by the largeness of its divaricating hinder elytral fascicles,
