THEGILIS.—TYLODERMA. 527 
condensed into scattered fascicles on the elytra and also clustered together on the median lobe of the 
pronotum ; the vestiture of the legs very sparse and fine, the tibis each with a line of fulvous hair-like 
scales near the apex. Head closely punctate, often feebly foveate between the eyes, and excavate on each 
side in front of them; rostrum somewhat thickly punctate to the tip, subcarinate at the sides towards 
the base. Prothorax much narrowed in front, the sides rounded anteriorly; thickly punctate, except 
along the smooth median line, the latter becoming cariniform on the median lobe, the flanks subgranulate, 
the ocular lobes usually dentiform in the ¢. LElytra at the base scarcely broader than the prothorax, 
widened for a short distance and then narrowed to the apex, the humeri subangular; with rows of 
-coarse oval punctures placed in shallow strie, the interstices thickly punctate, more or less convex, 
becoming costate towards the tip. Beneath very coarsely punctate. Legs stout; anterior femora 
unarmed, the others sulcate beneath, the intermediate pair obsoletely, and the posterior pair distinctly, 
dentate, the latter with a strong curved tooth on the lower inner edge towards the apex in the ¢; tibie 
with the outer carina moderately prominent and usually more or less hollowed before the apex. 
Length 104-14, breadth 51-7 millim. (¢ 2.)

This fine species has exactly the facies of a large Barid. The scales are easily 
abraded, the prothorax being almost bare. The curved tooth on the hind femora of 
the male is formed by an apical prolongation of the inner carina beneath. The ocular 
lobes of the prothorax are usually dentiform in this sex. The insect is found in 
decaying trees. Seventeen specimens.

Tyloderma is represented by numerous species in North America, two of which 
extend into our limits, and a few have been described from Tropical South America 
and the Antilles. To the characters given by Casey, it may be added that the outer 
row of punctures on the elytra is short. The genus is placed amongst the “ Tylodides ” 
by Lacordaire, and amongst the ‘‘ Cryptorrhynchides vrais” by Faust, the metathoracic 
episterna being very narrow. Tyloderma is one of the few Cryptorrhynchid genera 
with a six-jointed funiculus.
