HI. americaiiiiK Mots.— This species, which was taken by Motschulsky 



about the foot of trees at Mobile. Ala., remains unknown to us. Tbe antenna- 

 are not mentioned in tbe description, but we are to infer from the generic diag- 

 nosis that they are 10-jointed. The characters mentioned in the table are the 

 only ones contained in the description that are serviceable for a comparison with 

 parviceps, which aloue of our other species has 10-jointed antenna?. Length 

 " £ lin. ; width ji lin." 



Hab.— Alabama ( Mobile). 



HI. l'lidis sp. nov. — Of same size, color and appearance as parviceps, except 

 in following particulars: Head less transverse, the sides less strongly rounded. 

 Antennae 11-jointed. Prothorax with sides a little less evenly rounded and less 

 convergent behind. Elytra each with eight rows of foveate punctures, and 

 therefore with three elevated intervals instead of two. The two lateral rows of 

 punctures coalesce into a single row toward the base. (PI. Ill, tig. 7). 



Hab. — California (Ojai Valley; Los Angeles; Panimint Valley). 



Specimens were taken by me in the Ojai Valley in March, from 



the interior of a large woody fungus attached to the trunk of trees. 



M. I i - ii \ sp. nov. — Size, color and sculpture of parviceps. Head less trans- 

 verse : antennas 11-jointed. Prothorax angulate at sides, the margin slightly 

 concave behind the angulation. Elytra a little wider at base than the contiguous 

 base of the prothorax, but less conspicuously so than in parviceps ; the side mar- 

 gin, as viewed from above, a little more evidently angulate behind the humeri. 

 Front and middle coxae distinctly less widely separated than in parviceps. (PI. 

 Ill, fig. 8). 



Hab. —Texas (Columbus); California (San Benardino Mts.). Two 

 examples from the former locality, taken by Mr. Schvvarz in dry 

 debris of an old cotton wood tree, and one not appreciably different, 

 taken by myself in the latter locality on the under side of a log in 

 a slightly moist situation. 



M. albosignatus sp. nov.— Dark brown when mature, the chalky deposit 

 affecting more or less the margin of the elytra and presenting behind the middle 

 a conspicuous fascia, which is more or less interrupted at the suture. Head 

 longer than wide, sides feebly arcuate, a little convergent. Sides of thorax 

 strongly angulate and distinctly concave behind, parallel for a short distance 

 before the base; hind angles right; margin feebly or scarcely crenulate. Sculp- 

 ture of pronotum more pronounced than usual. Elytra at base not wider than 

 the contiguous base of the prothorax, sides conspicuously angulate before the 

 middle. Front and middle coxae more narrowly separated than in any other 

 species. (PI. Ill, fig. 9). Length 1 mm. or slightly less — our smallest species. 



Hab. — Florida ( Biscayne and St. Petersburg). Taken rather 

 abundantly at the former locality under moist bark of the Mastic- 

 tree (Slderoxylon mastiehodendron), by Mr. Schwarz, and at St. 

 Petersburg under wood chips on the shore of Tampa Bay by Mr. 

 Hubbard.
