2. L. GEMINATUS. — Thorax longitudinally indented ; strise of 

 the elytra geminate. 



Inhabits Pennsylvania. 



Body depressed, dark reddish-brown, with short, prostrate 

 hairs : head punctured : antennae rather robust, with short hairs : 

 thorax gradually a little narrowed behind, with numerous large 

 punctures ; middle of the disk widely indented longitudinally : 

 scutel convex, rounded : elytra depressed above; impressed striae 

 placed in pairs; interstitial lines punctured. 



Length three-twentieths of an inch. 



[This is a species of Bothrideres Er., but very different from 

 B. geminatus Hald., which was subsequently described as B. 

 exaratus Mels. — Leg.] 



3. L. H^MATODES. — Thorax with two indented lines; elytra 

 with large, deep punctured striae. 



Lyctus hsematodes ? Fabr. 



Body dark reddish-brown, a little depressed : head [263] 

 with large, not profound punctures ; an indented longitudinal 

 space each side, between the antennae : antennae short, robust : 

 thorax with large, somewhat deep punctures, and two dilated, 

 parallel, indented lines on the disk : margin a little ele- 

 vated, in the middle contracted ; elytra with dilated profound 

 striee or grooves, in which are dilated, not deeply impressed 

 punctures ; interstitial lines narrow, prominent. 



Length less than three-twentieths of an inch. 



This certainly approaches the description of L. hsematodes 

 Fabr., and probably is the same ; but as he describes that species 

 to be carinated on the thorax, I have made out the above des- 

 cription, that those who have an opportunity, may compare. 



I obtained may specimens under loose bark of the yellow-pine, 

 on Chinquoteague Island, in October. 



The three species above described, correspond with the charac- 

 ters of the genus Bitoma of Herbst, in having the antennae 

 shorter than the head and thorax, and the mandibles not very 

 obviously projecting; yet they appear to me to be very properly 

 retained in the present genus.
