152 CERAMBYCID^. 



of other families ; tiiat it lacks all the specialisations that are so remark- 

 able iu other divisions of Longicorns, while but little changes would suffice 

 to make it a member of other divisions, either of Ceramhycides or of 

 Prionides." 



The larva of Criocephcdus ferus is figured by Dr. Sharp (Trans. Ent. 

 Soc. ] 905, Plate ix. fig. 5) ; it is a broad fleshy grub, with the prothoracic 

 segment the longest and broadest, and with the body narrowed gradually 

 to the fifth or sixth abdominal segment and then again widened; the 

 apical segment terminates in two small spinose processes in the centre of 

 its margin; the sides of the whole body ax-e furnished with setse; the 

 legs are very short and terminate in rather a long single claw. 



C. rusticus, L. (Syst. Nat. x. 398, t. 75 ; Sharp, Trans. Ent. Soc. 

 Lond. 1905, 151) ; C. coriaceus. Mots. (Bull. Mosc. 1845, 89). Very 

 variable in size, form, and sculpture ; ferruginous-brown or fuscous- 

 black, never quite black, rather depressed ; head strongly depressed 

 between the antennte, the latter in the male sex with the ba^e distinctly 

 thicker than in the female ; labrum without a pencil of hairs in the fovea 

 or the middle of its area ; eyes with long hairs between the facets ; thorax 

 plainly transverse, uneven, with the sides more or less strongly rounded, 

 closely and somewhat granulosely sculptured ; elytra long, dull, with two 

 rather plain raised lines on the disc, which meet or become obsolete at 

 some little distance from apex ; there is also a more or less marked line 

 at the sides ; the surface generally is closely and subrugosely sculptured, 

 the space between the punctures being alutaceous ; legs plainly more 

 robust in the male than in the female. The species may be known by the 

 strongly transverse thorax and by the gular area being very indefinitely 

 limited, rugose in front and feebly punctate behind, and with only a few 

 suberect long hairs. L. 14-30 mm. The width varies from 4-7^ mm. 



Nethy Bridge, Scotland ; first found by Colonel Yerbury and subse- 

 quently by Dr. Sharp, Mr. Bishop, and others, This fine insect is 

 undoubtedly a native of Scotland, but, as it is found throughout the 

 temperate zone of the Old World in the JSTorthern Hemisphere, it is 

 sometimes imported, and a specimen has been found in a coal mine in 

 Wales which was almost certainly brought in in coal props. The species 

 is attached to Coniferse. 



C. ferus, Kraatz (Berlin Ent. Zeitschr. 1863, 107; Sharp, Trans. 

 Ent. Soc. Lond. 1905, 156). C. rusticus, vetr. ferus, Dej. (Cat. Coll. (not 

 described) Mulsant ; Long. Franc, ed. i. p. 4). C. ? jwlonicus, Mots. (Bull. 

 Mosc. 1845, 88). C. epibata, Schiodte (Kr. Tidskr. 3, ii. 41). Very 

 variable in size, male fuscous-black, female black ; thorax longer than 

 in C. rusticus ; elytra with the two raised costa? on the disc more distinct 

 and with traces of a third one between these ; the sculpture of the elytra 

 is vei-y fine and alutaceous, Avithout the punctuation of (7- rusticus ; in 

 these points, however, there is probably considei^able variation ; the 

 chief differential charactei, perhaps, lies in the labi-um, which is provided 

 with a pencil of hairs placed in a fovea in the middle near the front ; 

 there are, however, as Dr. Sharp points out (^.c. 156) numerous points
