715 (- -). PELKNOMUS PUSILLUS Dietz, 1896, 466. 



Differs from squamosus in having the "beak very stout, shorter than 

 head; eyes less convex. Scales on upper surface brownish with a brassy 

 lustre and more conspicuously mottled with larger white scales; scales of 

 under side ochreous, legs rufous, fourth tarsal joint longer, nearly equal 

 to the two preceding joints. Last ventral of male with a small longitudinal 

 fovea. Length 2 mm." (Dietz.) 



Known only from a single specimen in the Horn collection, 

 from Tarn-fa, Fla. 



716 ( ). PELENOMUS IMPRESSIVENTRIS sp. nov. 



Short-oval, subdepressed. Black or piceous, above rather thickly 

 clothed with reddish-brown scales, having a faint brassy tinge; elytra more 

 or less mottled with small patches of elongate pure white scales; under sur- 

 face rather thinly clothed with oval or rounded white scales, those on sides 

 of thorax and sternal side pieces yellowish. Beak stout, as long as head, 

 finely and densely punctate. Thorax one-half wider at base than long, 

 disc finely and densely punctate, less narrowed in front than in squamosus, 

 its apical margin not emarginate between the cusps which are quite small 

 and widely separated; lateral tubercles also small, acute. Elytra one-third 

 wider at base than thorax, humeri rounded, sides subparallel or feebly con- 

 verging to apical third, then broadly rounded to apex; intervals feebly con- 

 vex, the fifth slightly more elevated. Ventral segments 2 4 of male as de- 

 scribed in key, the fifth with a deeper transverse impression. Length 1.8 

 2mm. (W.8.B.) 



Lake Co., Ind., rare; Sept. 14. Tyngsboro, Mass., Oct. 2,

XIV. MECOPELTUS Dietz, 1890. (Or., "long"+ "skin.") 



Differs from Printout us only in the presence of ante-coxal 

 ridges, forming a prosternal canal for the reception of the ros- 

 trum in repose. The antenna! club is large, the first joint form- 

 ing half of its mass; other characters as given in the key. In 

 general appearance they do not differ from Pclenninn* Two of
