304 CURCULIONLD^E. 



1. M. striatus, n. sp. 



Robust, convex, black, thinly clothed with oval white scales, more 

 densely placed on the under surface, but easily removed by abrasion, 

 and of which but few remain in the specimen. Beak nearly smooth, feebly 

 impressed transversely at base. Prothorax wider than long, sides oblique, 

 rounded, very much narrowed in front, moderately constricted near the 

 tip, sparsely finely punctured, punctures less distinct towards the sides, 

 which are more obtuse than in the other two species. Elytra not narrower 

 than the prothorax, gradually less narrowed behind than in the other two 

 species ; strise well marked, rather deep, interspaces broad, flat, each with 

 a row of feeble punctures. Antenna with the first joint of funicle slender, 

 much longer than the second. Beneath rather coarsely punctured, but 

 not very deeply so on the flanks of the prothorax. Length 4.3 mm.; .17 

 inch. 



One specimen, Lake Harney, Florida, May 4th; Messrs. Hubbard and 

 Schwarz. Probably a female, in which case the male would have the pro- 

 thorax wider and more rounded on the sides, and the lateral edge more 

 compressed. 



2. M. puncticollis, n. sp. 



Robust, very convex, black, uniformly, but thinly clothed with silvery 

 white oval scales, more densely placed on the under surface. Head gla- 

 brous behind the eyes, punctured in front, nearly smooth behind; beak 

 punctured, scaly, not impressed at base; front scaly. Prothorax wider 

 than long, strongly rounded on the sides, hind angles rounded, lateral edge 

 nearly acutely defined; strongly narrowed in front, and rather strongly 

 constricted near the apex, which is scarcely one-half as wide as the base; 

 disc strongly punctured, more densely towards the sides, with a broad, 

 smooth dorsal space. Elytra narrower than the prothorax, broadly but 

 obliquely narrowed on the sides; strise fine, in some places indistinct, in- 

 terspaces broad, sparsely irregularly punctulate. Antennae with the first 

 joint of funicle twice as long as the second, which is longer than the third. 

 Beneath rather coarsely punctured; punctures of the flanks of the protho- 

 rax equally deep. Length 3.7 mm. ; .15 inch. 



Baldwin, Florida, June 10; many specimens; Messrs. Hubbard and 

 Schwarz. 



3. M. Isevicollis, n. sp. 



Robust ovate, very convex, almost gibbous, black, shining (sparsely 

 squamose, with linear white scales, which have been mostly removed by 

 abrasion). Beak sparsely punctured, feebly transversely impressed at base; 

 head convex, sparsely punctulate in front, smooth behind. Prothorax 

 tw r ice as wide as long, very convex, strongly narrowed in front, sides 

 obliquely narrowed, very strongly constricted about one-fourth from the 

 apex, which is half the width of the base; the latter is not truncate, but 

 very I roadly rounded; surface feebly and sparsely punctulate, lateral edge 

 nearly acutely defined. Elytra not narrower than the prothorax at base,
