scaling in the foveae only, and irregular patches of similar scales 

 along the sides of the sternum and two basal ventrites. 



Head not constricted behind the eyes, finely and closely punctate, 

 with a transverse depression on the forehead containing a large 

 median fovea. Rostrum about as long as its apical width, gradually 

 widening from base to apex, the sides straight; the dorsum finely 

 and closely punctate, with scattered larger punctures, a deep median 

 triangular depression and a small longitudinal impression on each 

 side of it ; the interantennal area deeply impressed. Antennae 

 with the scape exceeding the eye, moderately slender, very finely 

 and closely punctate and with sparse recumbent setae; funicular 

 formula: 2, 1, 3, (4, 5, G, 7), the apical joints being pear-shaped. 

 Prothorax as long as broad, subcylindrical, the sides very slightly 

 rounded, with a very shallow constriction near the base and a deep 

 one near the apex ; the apical margin truncate dorsally and shal- 

 lowly sinuate beneath; the dorsum with a very broad, almost 

 smooth, deep median depression, the adjoining costae fairly even 

 and irregularly punctate, the outer areas transversely rugose and 

 with a deep impression anteriorly. Scutellum small, somewhat 

 transverse, bare. Elytra subelliptical, the humeral angle very small 

 and obtuse, the lateral margins (as seen from above) much sinuatcd, 

 the apices each produced into a short blunt process, usually rather 

 closely approximated; the dorsal outline very gently curved, and 

 the declivity with a slope of only 40° ; the punctures forming regular 

 rows only on the inflexed margins, those on the disk large, deep and 

 transversely confluent, the interspaces forming irregular transverse 

 corrugations ; there are thus no regular intervals or costae, but the 

 sutural area is slightly flattened as far as the nominal 3rd interval ; 

 the scales short oval or subcircular, and slightly overlapping; the 

 irregular short curved setae mostly confined to the depressions, like 

 the scaling. Legs with fuscous scaling and slightly raised pale 

 setae ; the tibiae not denticulate and the hind pair not mucronate ; 

 the second joint of the front tarsi as long as broad. 



Length, 12-13 mm. ; breadth, 4-4i mm. 



Venezuela : Escorial, 10,000 ft. 



Described from thirteen specimens. 



The much reduced shoulders and the strong transverse 

 corrugations on the elytra give this species a distinctive 

 appearance. 



Exorides equatorius, sp. n. (Plate IV, fig. 10.) 



?. Integument black, thinly clothed with pale dull greyish green 

 scaling, which is densest between intervals 3 and 7 on the elytra
