OF AMERICA NORTH OF MEXICO. 31 



Found near the top of Yona mountain. The elytra are twice as long as the head 

 and thorax, a little dilated to the middle, from which place they are gradually and 

 somewhat obliquely narrowed. 



Group 10. 



This group begins the approach towards the Spojidylidce, by having the anterior 

 acetabula externally prolonged into an angle. By this character it differs from all 

 the preceding groups, except some members of the sixth, but these are immediately 

 distinguished by their cylindrical palpi; they are all depressed elongated insects with 

 rarely any armature to the thorax or elytra, the latter in a great majority of the 

 genera are rounded on the sides. The femora, as far as I have been able to examine, 

 are always very much clavate.

1. H. BAJULus. — Niger cinereo pubescens, thorace latitudine dupio breviore, longius villoso, linea dorsali 



calloque utrinque modice elevato Isevibus ; elytris coriaceo-punctatis, fasciis 2 obsoletis dense 

 pubescentibus. Long. •■i5 — -75. 



This species has most probably been introduced ; it is found only in the vicinity of 

 cities. Germar in a letter to Dr. Morris, states that it is different from the European 

 insect, but on comparison I do not detect anything worthy of note. Varies with the 

 elytra testaceous. 



2. H. BULLATUS. — Niger, ctnereo-pubescens, thorace latitudine triplo breviore, longius villoso, punctato 



obsoletissime in disco, linea dorsali vix conspicua, callo majore utrinque laevi; elytris postice angustatis, 

 testaceis, coriaceo-punctatis, fasciis 2 indistinctis densius pubescentibus. Long. -75. 

 Hald. 1. c. 



One specimen, New York. Only differs from the preceding by its wider thorax, 

 with the punctures of the disc obsolete, and by the elytra narrowed behind. It may 

 be merely an accidental monstrosity.
