medially ; elytra slightly longer than wide, parallel, obtusely rounded 

 at tip, the humeri greatly exposed at base ; stride feebly impressed and 

 coarsely, deeply punctate ; legs short, dark testaceous, the femora feebly 

 banded with sparse whitish slender scales jusi beyond the middle. Length, 

 2.5 mm ; width, 1.2 mm. Oklahoma (Atoka), Wickham. 



In all the species of Thysanoc?iemis and Flocetes the scutellum is 

 triangular, flat and densely squamose ; it is here elevated, narrower and 

 coarsely sculptured but virtually glabrous. 



Hamaba n. gen. 

 The species of this genus have the general structure and facies of 

 Thysatiocnemis, but are minute in size and have the antennal funicle 

 6jointed, though with the basal joint similarly large and stout; the club 

 shorter, being about as long as the first five funicular joints, 3-jointed, with 

 the sutures all distinct. The scutellum is flat, densely squamose and 

 triangular, the tarsal claws deeply and widely cleft and the femora 

 unarmed. The following is the type : 



ff. Bahameiisis n. sp. — Rather stout, dark, the humeri not paler ; legs 

 and beak more or less pale flavo-testaceous ; beak ( 9 ) not longer than 

 the prothorax, rather stout, tapering beyond the point of antennal inser- 

 tion, the latter at about the middle ; eyes large, convex, coarsely faceted, 

 narrowly separated on the front ; prothorax small, wider than long, 

 parallel, the sides straight, rounding and converging anteriorly, strongly 

 and densely punctured, ihe scales whitish at the sides, along the median 

 line and in a tranverse medial fascia ; scutellum small, flat, acutely pointed ; 

 elytra slightly longer than wide, parallel, obtusely rounded at apex, the 

 humeri well exposed at base, the strife not much impressed, strongly, 

 closely punctate, the pale scales forming a wide loose irregular subbasal 

 fascia, produced on the suture toward the scutellum, and, at each side, 

 enclosing a darker spot, also a transverse, strongly trisinuate fascia behind 

 the middle, the larger scales along the intervals, on the areas of paler 

 vestiture, narrow and elongate. Length, r.2-1.5 mm. ; width, 0.5-0.65 

 mm. Bahama Islands (Eleuthera and Egg Island), Wickham. 



The following is allied rather closely but appears to be distinct : 



H. dispersa n. sp. — Similar in general coloration and structure to the 

 preceding but relatively stouter, the elytra only just visibly longer than 

 wide, blackish, the much-exposed humeri rufescent, the beak rather longer 

 and very much stouter, with the antennjse inserted much beyond the
