Mr. Watkrhouse v)i tlie genus Calochrumus. 199 



C. rugatus, n. sp. (PI. 11, f. 7). 



Elougatus, nlger ; elytris piceo-testaceis, dense rubro-sericeis, 

 striis impressis, interstitiis convexiusculis, 2° et 4° siib-costatis $ . 

 Long. 5^ liu. 



Head gently convex, impressed on the forehead ; rostrum 

 extremely short, space between the antennal pit and base of the 

 mandible about half the diameter of the antennal pit. Antenna) 

 about -| the length of the elytra and (for the genus) rather slender, 

 the sixth to tenth joints slightly diminishing in length, and a trifle 

 more slender, eleventh joint a little longer, parallel, scarcely 

 acuminate at the apex. Thorax black, margined, delicately 

 jmbescent, disc transversely impressed behind the middle, deeply 

 impressed in front of and behind the oblique lateral ridge . 

 Penultimate segment of abdomen with a deej? incision.

C. 1-uber, n. sp. (PI. II, f. 8). 



Elongatus, niger supra, piceo-testaceiis dense rubro-sericeus ; 

 thorace medio longitudinaliter canahculato, lateribus bifoveatis ; 

 elytris minus elongatis unicoloribus, obsolete bicostatis 9 . 



Antenna) compressed, third joint as long as the two preceding 

 together, foiu'th a httle longer, truncate at the apex, fifth to 

 ninth nearly the same form, but gradually more obliquely 

 truncate at the apex, so that the lower anterior angle becomes 

 more acute but is not produced, the tenth joint is rather smaller, 

 veiy obliquely truncate, the eleventh narrow, parallel, acumi- 

 nate at the apex.

This species is very close to C. rvgatus, and I thought that 

 it might, ]ierhaps, be the female of that insect, but the lateral 

 obhque ridge of the thorax is placed more posteriorly (see fig.), 

 and the lateral impressions are not so well defined ; the space 

 between the antennal pit and the base of the mandible is also 

 much greater. 



C. velutiiiKS, n. sp. (PI. II, f. 9). 



Elongatus, piceo-niger, supra piceo-testaceus, dense flavo-rufo- 

 sericeus; thorace sat trausverso, medio canahculato, utrincpic 

 fortiter impresso ; elytris oljsolete bicostatis ; abdomine cyanco- 

 nigro. Long. 5^ lin.
