spection of the insect itself) whether any of my species of CraS' 

 pedophorus correspond with Hope^s. Mr. Westwood's report 

 confirms my doubt as to this species, although he observes that 

 it is of the same general form, and, coupled with Hope's de- 

 scription, leads me to consider the two species distinct. His 

 description is as follows: — "Long. lin. 8, lat. lin. 3i. Niger; 

 antennis atris, thorace semicirculari baud excavato, subdepresso et 

 crebrissime punctulato. Elytris sulcato-punctatis quatuor maculis 

 subquadratis flavis pedibusque nigris. Hab. In Sierra Leone. 

 This species has the two anterior spots covering six interstitial 

 spaces, while the posterior cover only five*.'' This description, 

 so far as it goes, corresponds with my species, except that in 

 mine the thorax cannot be called semicircular, or not excavated ; 

 it should rather be called conical, and it certainly is excavated, 

 especially posteriorly. Mr. Westwood has furnished me with a 

 sketch of the thorax of tropicus, which shows that it is more 

 semicircTilar and shorter than in coniciis. Hope's species also is 

 somewhat smaller. The number of interstices over which the 

 yellow spots extend (a particular which Mr. Hope gives as a 

 good specific character throughout the genus) corresponds with 

 that in his tropicus, excepting that the anterior marking some- 

 times covers the whole of the third interstice, at other times 

 scarcely impinges on it at all ; thus leaving it not quite clear 

 w^hether it covers five or six interstitial spaces.

Very closely allied to the ])rcccding species, and the same 

 description will answer for both, with the following exceptions. 



This species is rather smaller. Its head is somewhat narrower. 

 Its thorax is quite difl'erently shaped, being narrow, con- 

 stricted in front, and rather rapidly expanded behind ; the pos- 

 terior angles are obtuse, and not so much rounded as in co- 

 nicus. The elytra are shorter, not quite so convex, and the 

 interstices also are less convex ; the fulvous markings are nar- 

 rower, particularly the posterior spot, and the colour of the 

 anterior spots does not encroach on the third interstice, and is 

 thus confined to five instead of six interstices. The punctures
