Xylophilus Eonelli. 



In this genus the third joint of all the tarsi is lobed beneath, and the fourth 

 joint of the two anterior pairs is very small, and received upon the third. The 

 proper place is still not well determined: among the Anthicides it cannot remain 

 on account of the emarginate eyes.

York county, Pennsylvania ; Messrs. Melsheimer & Ziegler. Although by 

 the curious structure of the antennae of the male this beautiful species differs 

 from all the others below described, I can find no characters sufficient to cause 

 it to be separated as a genus. The feet vary in color, being sometimes yellow, 

 with only the posterior thighs fuscous: the antennas of the female are yellow; 

 the bands of the elytra are sometimes confluent, so that the elytra appear black 

 with yellow spots. The head is wider than the thorax, and the elytra are elon- 

 gate parallel, truncate at base, and nearly twice as wide as the thorax. 



2. X. n o t a t u s, ater, parcius cinereo-pubescens, capite thoraceque opacis 

 confertim punctulatis hoc quadrato, elytris thorace duplo latioribus convexis 

 nitidiusculis sat grosse punctatis, guttis utrinque ante medium fasciaque lata 

 pone medium flavis, antennis palpis pedibusque testaceis, femoribus posteri- 

 oribus infuscatis. Long. -08. 



One specimen found in Habersham county, Georgia. The two rounded yel- 

 low spots before the middle of each elytron seem inclined to coalesce into a 

 transverse fascia. The punctures of the elytra are most distant towards the 

 tip. 



3. X. pi c e u s, nigro-piceus, cinereo-pruinos us, capite thoraceque confertis- 

 sime punctulatis, opacis, hoc rotundato-quadrato, subtransverso, ad basim trans- 

 versim impresso, elytris thorace duplo latioribus convexis, punctatis, ante medium 

 versus suturam impressis. Long. -08. 



Middle and Southern States : no external sexual differences were perceived. 

 The feet and antennae are sometimes paler and almost testaceous. 



4. X. fa s c i atu s, niger nitidus, griseo-pubescens, capite thoraceque minus 

 subtiliter punctatis hoc transverso quadrato, elytris duplo latioribus convexis, 

 confertim punctatis macula maxima basali alteraque communi apicali fulvis; 

 antennis palpis pedibusque rufo-testaceis. Long. -12.

 Middle and Southern States. The difference between Euglenes Westwood 

 and typical Xylophilus is not obvious. 



5. X. signatus, testaceus, cinereo-pubescens, capite confertim punctato 

 fusco, thorace quadrato punctato, latitudine sesqui breviore, elytris grossius 

 confertim punctatis convexis, macula utrinque transversa sinuata nigra ad me- 

 dium ornatis. Long. # 09.

Middle and Southern States. The antenna?, as in the preceding, are gradually 

 thickened externally, the joints from the 3d to the 10th gradually broader, the 

 outer ones being transverse : the 11th is larger, ovoid, and acute at tip. The 

 transverse black spot of the elytra is sometimes broken into two rounded dots.
