FALL AND COCKERELL.

Phyllotrox quadrifollis n. sp.— Ferruginous, rather sparsely clothed 

 with recumbent golden-yellow pubescence; metasternum, tarsi and antenual 

 club blackish. Head coarsely densely punctate; eyes rounded, distant from the 

 prothorax; beak about three-fourths the length of the prothorax, just visibly 

 wider at apex, feebly arcuate, coarsely closely punctate and substriate. Antennte 

 inserted at apical third, scape directed against and barely attaining the eye ; 

 funicle short, stout, outer joints wider and very strongly transverse, merging 

 into the club. Prothorax subquadrate, sides broadly arcuate and very sliglitly 

 convergent nearly to apex, then suddenly narrowed to the feeble apical constric- 

 tion ; surface coarsely closely punctate. Elytra twice as long as the prothorax, 

 and barely one-fourth wider; about two-thirds longer than wide; strife scarcely 

 impressed, closely punctate, the punctures tending to become irregular toward 

 the base; intervals with a single or irregular double series of finer punctures. 

 Metasternum densely rather finely punctate, the preceding segments more finely 

 and sparsely so. Legs as in P. nubifer but stouter. Length 2.4-2.8 mm. 



Beulah. Two examples on Carduus parryi (Cockerell). 



There is very little sexual difference in the length of the beak, 



but the male has the fifth ventral eniarginate and somewhat shorter 



than in the female, the pygidium produced, convex at apex and 



plainly exposed. This species resembles the paler forms of nubifer 



in a general way, but is a little larger, with broader thorax, the 



elytral humeri consequently less widely ex})osed, the legs thicker, 



the beak shorter ; the pygidial groove does not attain the apex as it 



does in nubifer. 



HYPOL.ESCHUS new genus. 



Beak a little longer than the head and prothorax, rather slender, 

 cylindrical, evenly arcuate. Antennae inserted beyond the middle, 

 scape not quite reaching the eyes; funicle 7-jointed, first two joints 

 longer, outer joints strongly transverse; scrobes moderately deep, 

 directed against the lower portion of the eyes, which are broadly 

 rotundate oval and not very convex. Prothorax cylindrical, nar 

 rowed and slightly constricted at apex. Elytra much wider than 

 the prothorax, finely striate, strise closely punctate. Prosternum 

 before the coxfe rather longer than the diameters of the coxal cavi- 

 ties ; coxfe contiguous ; middle coxae separated by half their own 

 diameters; metasternum longer than the first ventral segment. 

 Ventral segments one, two and five long, third and fourth together 

 equal to the second but scarcely as long as the fifth ; first suture a 

 little arcuate at middle. Legs rather slender, tibise straight, not at 

 all mucronate or unguiculate. Tarsi not very stout, pilose beneath, 

 third joint wider and deeply bilobed ; claws appendiculate. 



This genus is related to Elleschus, but differs in the longer and 

 more slender legs and beak, unarmed tibise and finer and sparser
