Body rounded, subovate, black : bead with small numerous 

 punctures : antennae piceous, capitulum pale fulvous : thorax 

 with small numerous punctures, less distinct on the disk : elytra 

 irregularly punctured ; first and second dorsal striae entire, well 

 impressed ; third and fourth striae less deeply impressed, extend- 

 ing from the base to near the tip, where they are abbreviated, 

 the latter shorter : feet piceous : tibiae dilated in the middle, 



Length nearly three-twentieths of an inch. 



Allied to the J) unctatus Payk., but sufliciently distinct. Rare. 



[Belongs to Dcndrojihilus. — Lec] 



20. H. TRANSVERSUS. — Thorax with two grooves and a trans- 

 verse impressed line. 



Body oblong, brownish-black, with large numerous punctures ; 

 head somewhat concave above the antennae, and before the antennae 

 elongated : thorax with a large deep groove on each side, and a 

 transverse, impressed, very distinct line rather before the middle : 

 elytra with large, dense, longitudinal punctures, [46] giving a 

 somewhat rugose appearance to the surface. 



Length rather more than one-twentieth of an inch. 



About equal in size to the csesus Fabr., of Europe, to which it 

 is very closely allied. 



[Belongs to Plegadcrus. — Leg.] 



Family 7. — With elevated lines. 



21. H. ALTERNATUS. — Tliorax with six elevated lines; lines 

 of the elytra with intervening smaller ones. 



Mister sulcatus Melsh. Catal. 



Body oval-orbicular, convex, brownish-black : thorax with six 

 prominent lines, the two middle approximate on the anterior mar- 

 gin ; the exterior line abbreviated before ; lateral edges promi- 

 nent ; intervening grooves punctured : elytra with about four 

 elevated lines, and a common one ; intervening spaces with 

 smaller elevated lines : anal segment with three elevated lines : 

 beneath with large punctures : feet piceous. 



Length less than one-tenth of an inch. 



Certainly not the sulcatus Fabr., to which, however, it is some- 

 what similar as regards the sculpture of the elytra, but in the 

 position and number of the thoracic lines it is somewhat like the 

 striatus Fabr. Rare. It belongs to the genus Onthophitus of 

 Leach. [47]
