Gyll.; coriaria, Kr.; longicornis, Grav., and melanaria,

the Madeiran ‘ H. longula”’ proving to be specifically 
distinct from the Canarian form, which last differs in no 
respect from the Huropean type. * 
(Sp. 1261) Homalota sanguinolenta. 
A more careful examination, during the past winter, 
of a very extensive series of this Homalota has convinced 
me that the form which I have hitherto recorded as the 
“‘var. 8” is in reality specifically distinct; and I am 
the further corroborated in this from the opinion of Dr, 
Sharp—who considers that there can be no question on 
the subject. It will perhaps therefore be desirable to 
give an emended diagnosis of the type, and afterwards 
(in order to point out the distinctions more accurately) 
a comparative one of its ally. 
Homalota sanguinolenta. 
H. aptera, subnitida, dense rugulosa-punctulata, plus 
minus infuscate rufo-testacea, fulvo-pilosa; capite abdo-

dilatato) obscurioribus, 7. e. seepius piceis; prothorace 
lato, ad latera rotundato; elytris brevibus; antennis 
fusco-piceis, ad basin pedibusque testaceis.

* Although the present memoir pertains to the Madeiran and Canarian 
archipelagos only, I may perhaps just state that of the six species of 
Homalota which I recorded for the Cape Verde Group, five have lately 
been examined by Dr. Sharp—who remarks concerning them as follows: 
H. coriaria, “differs in no respect from the usual, more northern type ;” 
subputrescens, ‘‘ distinct from the Canarian H. putrescens, Woll., next to 
which it must be placed; clientula, ‘‘this seems to be a little more 
strongly punctured than the ordinary European form, and might perhaps 
come nearer in reality to the H. orbata;”’ glareosa, ‘*a very distinct species, 
to be placed next to H. testudinea;”’ and carbunculus, “ a well-marked little 
species, of the aterrima group.”
