304 CURCULIONTDJE. 



[LeConte. 



1. M. striatus, n. sp. 



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

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

 and of Aviiich 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 liuel}' punctured, punctures less distinct towards the sides, 

 which are more obtuse than in the other two species. Elytra not nari'ower 

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

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

 a row of feeble punctures. Antenme 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 whicli 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, Avhich is scarcely one-half as wide as the base; 

 disc strongly punctured, more densely towards the sides, with a l)road, 

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

 obliquelj' narrowed on the sides; stria) fine, in some places indistinct, in- 

 terspaces broad, sparsely irregularly punctulate. Antennae Avith 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- 

 ra.x ecpiall}' deep. Length 3.7 mm. ; .15 inch. 



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

 Schwarz. 



3. M. IsevicoUis, 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 

 twice as wide as long, very convex, strongly narrowed in front, sides 

 obliqueh'^ narrowed, very stronglj' constricted about one-fourth from the 

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

 very broadly rounded; surface feebly and sparsely punctulate, lateral edge 

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