OF AMERICA NORTH OF MEXICO. 169 



3. L. BiusTUS, testaceus, undique dense breviter cinereo-pubescens, punctis fuscia variegatus, tborace vix 



inaequali, lateribus antice rolundatis, nigris, augulo lateral! rotundato, elytris lineis tribus minus elevatis, 



punctis vix acutis interruptis, macula magna apicali leviter infuscata, lateribus antice nigris, antennis 



nigro-annulatis, tarsis nigris. Long. -18 — -27. 



Southern and Middle States. Dr. Zimmerman has told me that it is Amniscus 



biustus Klug. (probably unpublished) and that it occurs also in Cuba. The markings 



resemble very much Liopus alpha, but that is a much less robust insect, with the 



first joint of the posterior tarsi long. 



4. L. PERPLEXUS, testaceus fusco cinereoque pubescens, thorace parce punctato, dorso 5-tuberculato, tuberculis 



duobus anterioribus distinctioribus, lateribus tuberculo obtusissimo, elytris grosse vix seriatim punctatis, 

 punctis paucis elevatis basalibus, alterisque pone medium, lateribus antice, strigaque pone medium 

 obliqua vix obscurioribus. Long. -5. 



Amniscus per_plexus Hald. 46. 



Georgia ; very rare. 



5. L. MACULA, testaceus, vel piceus, cinereo-fuscoque pubescens, ssepius fulvo-variegatus, thorace punctato 



dorso tuberculis 5 obtusis nigris, lateribus rotundatis vix sinuatis, cinereis, elytris grosse punctatis lineis 

 tribus subelevatis interruptis vix distinctis, macula magna laterali cinereo-alba paulo pone medium 

 ornatis, antennis fusco annulatis. Long. -S. 



Lamia macula Say. J. Ac. Nat. Sc. 5, 268. 



Amniscus macula Hald 48. 



Amniscus sticticus .j.Dej. Cat. Hald. 48. 



Middle States ; common also at Lake Superior. The white spot of the elytra 

 sometimes extends to the suture, forming a broad band. The elevated lines of the 

 elytra are most commonly entirely obliterated. 



6. L. COMMIXTUS, testaceus, supra fusco-variegatus, brevissime pubescens, tborace confertissime subaciculato, 



tuberculis 5 discoidalibus fere obsoletis, ad basin constricto, tuberculo lateral! subacuto, elytris grosse 

 punctatis, lineis tribus subelevatis suturaque breviter nigro-penicellatis ; macula parva externa pone basin 

 pallida, antennis podibusque annulatis. Long. -25 — -36. 



Amniscus commixtus Hald. 47. 



Amniscus punctahis Hald. 49. 



Middle and Southern States. The specimen of A. punctatus given me by 

 Haldeman, does not differ from his A. commixtus. The fuscous spots of the elytra 

 in well colored specimens form a transverse ring behind the middle, sometimes the 

 posterior part of the ring is wanting, and there remains only an oblique band reaching 

 the margin. 



6. L. COLLARis, "Front, uniformly dull cinereous, medial line strongly impressed, antenna and feet annulate: 

 pi-othorax thickly punctured, a large tubercle in the middle posteriorly, and another each side between it 

 and the lateral tubercle, elytra punctate, basal angles glabrous black, whence a dark brown irregular 

 band extends backwards toward the middle, and then narrows to the suture, one or two black spots near 

 the suture posteriorly, suture with a dark row of points ; apex subentire ; metasternum with yellowish 

 hair, indistinctly dotted with brown: groundcolor dull testaceous." Long. -4. 

 Amniscus coTlaris Hald. 46. 



Alabama. I have not examined this species.
