268 MR. c. o. WATERHOUSE ON [Feb. 15, 



are slightly prominent; the disk is very strongly punctured, but 

 the punctures are not very numerous, although from their large size 

 there is not much space between them; the sides are rusty yellovr. 

 The elytra are rusty yellow, with an oblong black spot common to 

 both elytra at the scutelluni, and the apical third is also black ; each 

 elytron has three strong costse, the lateral one is rather less strong 

 than the others, and at the apex turns aways from the apical spine : 

 the first and second interstices have two lines of strong punctures, a 

 fine ridge dividing the lines at the apex ; in the third interstice 

 there are three Unes of punctures at the apex ; the sides are finely 

 serrated ; the external angle at the apex is produced into an acute 

 spine, which is slightly concave at its base above. Tbe middle of 

 the sterna, and the intercostal process of the abdomen are pitchy- 

 red ; the legs are tinted with seneous ; the femora have the base 

 pitchy-red, the four posterior femora have a small acute spine near 

 the apex below. 



.31. Odontota annulipes, n. sp. (Plate XXX. fig. 18.) 



O. nigra, opaca ; fronte, /horacis lateribus, elytrisque ferrugiaeo- 

 ochraceis, his sutura nigra,fenioribus basiferrugineo-annulatis. 



Long 4 1 lin. 



Antennas moderately long and stout. Thorax a little impressed 

 at the base, with a very fine raised Hne in the middle in front. 

 Each elytron has four costse ; the two dorsal ones are very strong ; 

 the third is sharp over the shoulder, interrupted in the middle, and 

 very fine at the apex ; the fourth is entire but fine ; the lines of 

 punctures are strong and distinct ; the suture and a small mark 

 under the shoulder are black. The middle of the sterna and iuter- 

 coxal process of the abdomen are pitchy yellow. 



32. Odontota? sp. inc.* 



0. nigra, opaca ; elytris sanguineis, basi apiceque nigris, ad apicem 

 obtuse rotundatis, breviter acute serratis. 

 Long. 3| lin. 



A single example without antennae, which I therefore indicate as 

 a species without giving a name.

 Hab. Ecuador. 

 This species is known to me only from description. 



34. Metaxycera quadriguttata, u. sp. (Plate XXX. fig. 21.) 

 M. sanguinea ; elytris olivaceo-cEneis, singulis inaculis duabus 



sanguineis. Long. 4g lin. 

 Thorax velvety, shining on the disk in front, where there is a 

 well-marked longitudinal impression. Scutellum pitchy. Elytra 

 depressed on the back, finely crenulate at the sides, and more di- 

 stinctly so at the apex ; the disk of each elytron is dull and slightly 

 velvety-black ; the lines of punctures are very deep and distinct ; 

 ^ The genus is doubtful, there being no anteunrc. — C. W.
