3. TRICHODECTES SUBROSTRATUS. (Louse of the 

 Domestic Cat.) 



Clypeus elongate, triangular ; apex bituberculate. 



Trichodectes subrostratus. Nitzsch. Germ. Mag. iii. 296. Steph. Cat. pt. 

 ii. p. 330. Burmeister Handbuch ii. pt. ii. p. 436. spe. 4. Pediculus 

 Canis. O. Fabr. p. 215. ? 



That this species is a native of Britain there can be little 

 doubt, but as I have sought it in vain, I am compelled to 

 substitute in place of a general description, Dr. Burmeister's 

 specific character.

Plate XVII. Fig. 5. 



Head and thorax bright fulvous-yellow, the former sub- 

 orbicular, with four angular black spots on the anterior 

 margin, and two short fasciae at the base.

 ginate, with two angular black spots, surrounded with chest- 

 nut in front, and one in a broad chestnut band before the 

 eyes, lateral margin deeply sinuate, base truncate, with two 

 short black fasciae at the occiput; antennae clavate, the first 

 joint large, second the longest, obconical, third short; pro- 

 thorax short and transverse, posterior margin sinuate and 

 ciliated ; metathorax transverse, rather wider than the head, 

 with two oblique impressed lines at the lateral angles ; ab- 

 domen broad and ovate, pale yellow, segments nearly equal,

For the only specimens of this Insect I have ever seen, 

 I am indebted to the kindness of Dr. Southby, of Ames- 

 bury, Wiltshire, who found them on the head of a Fox 

 (Canis Vulpes).
