therefrom (when cleaned) by the trifoveate base of the prothorax, arid the sinuously 

 swollen margins of the latter. The sculpture is almost always entirely hidden by a 

 greasy incrustation. The colour is variable. 



5. Metamasius big at t atus, sp. n. (Tab. V. figg. 13, 13 «, <s .) 



c? . Elongate, subfusi form, broad, flattened and opaque above, black, the elytra each with a small fulvous spot 

 at the middle of the third interstice. Head rather small, finely punctate, with a deep frontal fovea ; 

 rostrum feebly curved, as long as the head and prothorax, comparatively slender, closely punctured, 

 becoming smooth and somewhat tapering towards the tip, obsoletely sulcate and crenulate, and also sub- 





angulate near the apex, beneath, the widened basal portion with an impressed line. Prothorax as long 

 as broad, subcorneal, deeply bisinuate at the base, broadly depressed on the disc posteriorly, very sparsely, 

 finely punctate. Scutellum elongate-subtriangular, flattened. Elytra much wider than the prothorax, 

 oblong-subcordate, finely striate, the striae with scattered punctures, the second and third sinuous at the 

 middle, the interstices broad and almost flat. Pygidium sparsely punctured. Beneath sparsely punctate, 

 the ventral excavation shallow. Legs elongate ; anterior femora with a fringe of short, and the anterior 

 tibise fimbriate with long, hairs ; tarsi slender, the third joint very broadly dilated. 



Length 11|, breadth 4^ millim.

Hob. Guatemala, Cerro Zunil, 4000 feet, Pacific slope {Champion). 



One example. This species may be known by the long and rather slender rostrum, 

 the conical, basally depressed prothorax, the single small spot at the middle of each 

 elytron, the widely separated anterior coxse, the strongly ciliate anterior tibiae ( 6 ), and 

 the broadly dilated third tarsal joint. 



6. Metamasius bigeminatus, sp. n. (Tab. V. figg. 14, 14 a, $ .) 



Elongate-rhomboidal, rather narrow, opaque above, black, the elytra each with two large, oblong-oval, sub- 

 contiguous, fulvous spots on the disc (on the widened portion of the third and fifth interstices) just 

 beyond the middle, the punctures filled with a brownish incrustation. Rostrum feebty curved, slender, 

 cylindrical, nearly half the length of the body, almost smooth, the short, broad, abruptly widened basal 



coxse widely separated. Legs rather slender. 

 Length 11|, breadth 4^ millim. ( $ .) 



Hab. Mexico, Toxpam in Vera Cruz {Salle). 



One specimen. A remarkably distinct form, with two large, oblong, subcontiguous 

 fulvous spots on the disc of each elytron just beyond the middle and the interstices 

 widened to make room for them. 



7. Metamasius sellatus, sp. n. (Tab. V. figg. 15, 15 a, s .) 



Subelliptic, broad, opaque above, the elytra each with a rather broad, transverse, angulate ochreous or rufous 

 fascia (sometimes enclosing a small black spot on the third interstice) just before the middle, the fascia 

 narrowing outwards and nearly reaching the suture and outer margin. Rostrum curved, nearly as long 

 as the prothorax, moderately stout, gradually widened at the base, obsoletely punctate in the g , almost

portion closely punctate, the frontal fovea deep. Prothorax conical, about as long as broad, bisinuate 

 at the base, sparsely, finely punctate, the disc broadly excavate posteriorly. Scutellum elongate- 

 subtriangular, narrow, flattened. Elytra oblong-subcordate, very finely striate, the striae 2-5 strongly 

 sinuate at the middle, all with widely-scattered rather coarse punctures, the interstices flat. Pygidium 







sparsely punctured, subcarinate towards the tip. Beneath very sparsely, finely punctate. Anterior
