Corexide. 339 
intermediate between fossarum and Scotti. Under these 
circumstances I feel that I must leave it as a doubtful 
species till more specimens turn up. 
L. 53 mm. 
Isle of Harris, Jenner Fust. 
(Suse. CALLICORIXA, B. White.) 
C. preusta, Fieb. (socia, D. § 8. ; Wollastoni, D. § 8.). 
—In form, colour and markings resembling distincta, but 
known at once by the large black spot at the apex of the 
first joint of the posterior tarsi (this is best seen from be- 
neath) ; inthe ¢ the anterior pal are elongate, suddenly 
dilated at about half their length from the base, the dilated 
portion concave, and bent forwards, apex subtruncate ; 
a spot on the tibia, and another on the dilatation of 
the tarsus, usually black; pronotum with about nine to ten 
irregular pale lines, its angles obtuse; markings of the 
corium narrow, not very much broken ; intermediate claws 
slightly shorter than the tarsi. In var. Wollastoni the 
markings are very obscure and ill-defined. 
L. 7 mm. 
Not rare and generally distributed. 
C. sodalis, D. 5 S.—This species, of which I have only 
seen a male and female kindly lent to me by Mr. Douglas, 
appears only to differ from preusta in the shorter claws of 
the intermediate tarsi, which in both specimens are only 
about two-thirds as long as the tarsus. The spot on the 
hind tarsus is only over the inner apical angle. 
L. 64 mm. 
Gosforth, Bold. 
C. Boldi, D. § S.—I have not seen the unique ¢ 
example of this species, which is distinguished by the 
central markings of the clavus being longitudinal; the 
spot on the hind tarsus nearly resembles that of preusta. 
Only one example being known, one cannot avoid a
