652 Mr. J. O. Westwood on the Paussida,

The detailed specific description of Paussus Bucephalus given 
by Gyllenhal in the Appendix to Schonherr’s Synonymia ln- 
sectorum, and the accompanying figure, together with the obser- 
vations upon the species by Dalman in the Analecta Entomolo- 
gica, and those by Latreille in the new edition of the Regne 
Animal , vol. v. p. 93. have enabled me to draw the preceding 
characters of this otherwise undescribed genus. Dalman ob- 
serves, “ Hanc speciem a reliquis Pausis nimis distare et vix

Schcenherri Syn. iii. App. tab. 6. figuras hujus et Pausi den - 
ticornis” ( Platyrhopalus unicolor mihi) “ comparare voluerit. 
Etenim in illo et ceteris veris Pausis, caput thorace multo est 
minus, oculi verb magni, et prominentes ; cum in Pa?iso Buce- 
phalo, caput thoracis latitudine, oculi minuti, et os etiam alis 
modo
