spinam rectis, femoribus basi testaceis. Long. -25. 

 Hald. 49. 



The obliquity of the sides of the thorax distinguishes this species. My specimen 

 is from Georgia, and in a very bad condition. 



B. Corpus elongatum, elytris apice rotundatis, vel vix truncatis femoribus posticis 

 vix clavatis : mesosternum apice acutum. 



4. L. FACETUS, fuscus, breviter cinereo-pubescens, thorace antrorsum angustato, spina ante basin sita, lateribus 



antice rectis, elytris punctatis, macula obliqua humerali, postice cum macula magna laterali conjuncta,

Lamia faceta Say. J. Ac. Nat. Sc. 5, 271. 



Amniscus facetus Hald. 49. 



Middle and Western States ; the pale spots of the elytra are more or less extended, 

 and sometimes include fuscous spots : the antennae are very rarely fuscous at base : 

 the male has the posterior femora moderately clavate. 



5. L. siGNATUS, fusco-testaceus, tenuiter cinereo-pubescens, thorace antrorsum angustato, spina laterali ante 



basin sita, lateribus rectis, elytris punctatis testaceis maculis paucis fuscis nebulosis, alteraque majore 

 antrorsum obliqua pone medium, fere ad suturam extendente, antennis pedibusque testaceis, femoribus 

 medio, tibiis apice infuscatis. Long. '25. 



One specimen ; New York. The first joint of the antennae is fuscous : the punc- 

 tures of the elytra are smaller towards the tip, by which character and by its larger 

 size, it may be readily separated from the preceding. 



6. L. sYMMETRicus, testaccus breviter dense cinereo-pubescens, thorace fusco lineato, antrorsum angustato, 



lateribus rectis, spina vix ante basin sita, elytris subtiliter parce punctatis, maculis oblongis fuscis 

 (marginalibus confluentibus) ornatis, pedibus fuscis, tibiarum femorumque basi testacea. Long. -32. 



Hald. 50.
