collection at the Norwich Museum, and it appears to agree very well there- 

 with, excepting in tlie ovate spiracles. Its relation to C. stomaticus seems 

 to be very close, though the areolet is parallel-sided (as figured by him) 

 and the legs darker. It does not appear to have been recognized, nor 

 even mentioned, upon the Continent. 



Cameron took the only known specimens, a male and three females, 

 near Lamlash, in Arran, towards the middle of September.

Head nearly cubical, genal costa not inflexed ; clypeus strongly dis- 

 creted, its apex broadly rounded, with a central triangular excision which 

 is obsolete in the $ ; mandibles elongate, with acute teeth, of which the 

 upper is the longer. Antennae short ; post-annellus a little shorter than 

 the slightly excised scape. Abdomen smooth and shining, black. Tibiae 

 not or hardly spinulose. 



This genus is said to agree to a certain extent with Cubocephalus, though 

 differing materially in the conformation of the mandibular teeth, the less 

 cubical head, the not or scarcely inflexed genal costa, triangularly excised 

 clypeus, more nitidulous and apically compressed abdomen, slightly longer 

 and apically sub-attenuate antennae, straight and shorter terebra, obvious 

 frontal puncturation and pale orbital line. Thomson himself thought his 

 genus probably synonymous with Demopheles.

 coarsely and somewhat closely punctate ; black, with frontal orbits white

 immaculate, of S with callosities before and beneath the radix, white ; 

 niesonotum sub-glabrous and nitidulous, obsoletely punctate, with the 

 notauli short; mesosternal sulcus deeply impressed and reaching beyond 

 the centre ; metathorax rugose, with the areola narrow and sub-obsolete ; 

 petiolar area distinctly impressed centrally ; apophyses obtuse, spiracles 

 circular. Scutellum black and deplanate. Abdomen elongate-lanceolate 

 and apically sub-compressed, glabrous and nitidulous, with segments six

 basal segment slightly curved laterally, dorsally deplanate and aciculate
