OF AMERICA NORTH OF MEXICO. 25 



The body is rather robust and convex, having the appearance of a Lamia, in which 

 group it was placed by Mr. Haldeman, but from which it is abundantly distinguished 

 by its porrected head, facial antennae, compressed palpi, and simple anterior tibiae. 



1. A. CONFUSA. — Punctata, nigra dense fulvo-pubescens, thorace disco margineque lateral! minus dense 

 pubescentibus ; elytris maculis plurimis transversis, parvis, glabris, laevibus. Long. -33. 

 Clytus confusus, Say. 

 Atimia trisiis, Hald. 



Middle and Northern States. 



Group 8 



Is distinguished from all the other sections of the present tribe by its perpendicular 

 front : the antennae being inserted so high on the head as to produce a large quadrate 

 face, almost as in the Lamia. The femora are always clavate, and the anterior 

 acetabula round. The thorax is convex and sometimes even compressed. 



This group approaches very closely the Saperdoid and Dorcadoid LamicB, and can, 

 indeed, only be separated by a reference to the diagnostic characters derived from the 

 palpi and anterior tibiae. The femora are dilated in all Clijti, whilst they are filiform 

 among LamicB. For this reason I have separated Clytus supernotatus, Say, and 

 pygmaus, Hald., to form new genera among the Lamia : both of these species have 

 the anterior tibiae obliquely sulcate inwards. The large Clyti with yellow bands 

 have already been united with Arhopalus, since their femora are scarcely clavate, 

 their thorax subdepressed, and their front only slightly deiiexed. 



CLYTUS, Fahr, 



Antennae breviusculae, crassiusculse, pubescentes minime pilosse. 

 Oculi subtriangulares, supra emarginati. 

 Thorax scaber, convexus, non compressus, baud armatus. 

 Elytra baud gibbosa ; corpus pubescens. 



I have separated the Clyti with gibbous elytra, on account of the antennae being 

 much thinner than in the genuine Chjti, and somewhat pilose towards the base. 



A. Femora posteriora apice spinosa, pedes postici longissimi. 



1. C. scuTELLARis. — Fuscus, thoracB latitudine non longiore, scabro, medio longitudinaliter elevato, 

 margine antico posticoque fasciaque tenui interrupta flavis, elytris basi rufis, scutello, lineisque 3 flavis, 

 1™* antice concava, secunda postice concava, 3'" extus obliqua ; apice truncata, spina externa armata : 

 antennis pedibusque rufis, clava femorali fusca. Long. -33 — '51.
