TOMICINI. 3G9 



tinctly punctured, with numerous rows of short pale bristles ; posterior 

 declivity convex, suturaf point small, less prominent than in the other 

 species. Length 1.7 mm. ; .07 inch. 



Haulover, Florida ; Fehruar}', Messrs. Hubbard and Schwarz. One 

 specimen. The eyes are more coarsely granulated than in the other species, 

 and there is no gular space between them. 



4. M. rudis, n. sp. 



Cylindrical, proportioned like M. suturalis, nearly black, rather shining, 

 antennte reddish-brown, sutures of the club forming broad curves; first 

 joint with a tuft of hairs near the tip. Head very deeply excavated (almost 

 as in Xi/loterus c^) ; eyes widelj- distant below. Prothorax somewhat longer 

 than wide, broadly rounded in front, sides parallel behind; surface sparsely 

 granulate behind, rough with numerous tubercles in front. Elytra scarcely 

 pubescent, rugosely punctured; punctures large, arranged in approximate 

 rows; interspaces rough with small acule tubercles on the declivity which 

 is convex, except near the tip, which is concave; sutural point well de- 

 veloped. Length 2.5 mm. ; .10 inch. 



Detroit, Micliigan; Messrs. Hubbard and Schwarz; one specimen. The 

 tibia; are feebly toothed on the outer edge. 



5. M. hirtellus, n. sp. 



Cylindrical, of the same form as M. suturalis, dark brown, thinlj^ pubes- 

 C3nt with fine yellowish sub-erect hair. Head flat, with a frontal tuft of hair ; 

 eyes widely separated beneath. Antenna; with the scape more densely 

 fringed than usual; club small, rounded; sutures nearly straight. Pro- 

 thorax longer than wide, nearly semicircular in front, densely but finely 

 granulate behind; asperate with numerous sharp tubercles in front, disc 

 feebly impressed, and more hairy each side of the median line behind the 

 middle. Elytra rugosely punctured; punctures arranged in rows; de- 

 clivity rough with small tubercles; convex, sutural point prominent. 

 Length 2.7 mm.; .11 inch. 



One specimen from Southern California, collected by Mr. Hardy and 

 kindlj" given me by Dr. David Sharp. The tarsi are longer and more 

 slender than in the other species. 



THYSANOES n. g. 



This genus is allied to Micracis; the front tibiiie are of the same parallel 

 form, as wide at base as at tip, and not serrate on the outer edge; the an- 

 tennse are, however, quite different; the scape is fringed as in Micracis; 

 the first joint of the funicle is longer than wide; thicker at the extremitj^; 

 the remaining five joints are very distinctly separated, and become rapidly 

 w^ider and transverse, by being prolonged at the upper side; thej' are also 

 fringed with very long hair; the club is elliptical, compressed, rather shining, 

 sparsely hairy, without distinct sensitive surface; without sutures on the 

 inner face, with two indistinct sutures on the outer face, of which the lower 

 one seems straight, and the distal one curved. The eyes are large, trans- 

 verse, coarsely granulated, and not emarginate; they are separated beneath
