72G (11,072). PHYROENUS MURICEUS Germ., 1824, 281. 



Larger and relatively broader than divergens and similarly colored. 

 Head and beak roughly and densely scaly, the former strongly, transversely 

 impressed; beak not quite as long as thorax, feebly bent, roughly and 

 densely sculptured. Thorax very nearly as long as wide, angulate at sides 

 before the middle, the disc very uneven, the median impression broad and 

 feeble; punctures very dense but even and rather fine. Elytra about 

 twice as wide as thorax, not longer than wide; intervals alternately strong- 

 ly ridged and flat; punctures coarse and rather uneven. Second abdominal 

 segment but slightly longer than third (nearly as long as the next two in 

 divergens), the basal segment not more coarsely punctate, but having in 

 addition to the finer punctures others much larger and more widely scat- 

 tered. Length 5.4 mm. 



In Slosson collection from Key West, Fla. (Rchwarz.} P. 

 lullatus Casey (1892, 458), described from Arizona is, according 

 to Champion, a synonym. 



II. CONOTRACHELUS Schoii., 1837. (Gr., "conical" -f "thorax.") 

 The characters of this enus have been full set forth under 





the subtribal heading and in the key to genera. The antennal 

 grooves are not confluent behind and the hind femora are not 

 club-shaped. The genus is confined to the western Continent, 

 more than 40 species being known from the United States, 28 of 

 which occur east of the Mississippi River. Many of them are 

 very injurious to cultivated fruits, especially the plum, peach, 

 apricot and quince; others attack the stems of plants; all pupate 

 i:i the ground. For convenience of treatment they are separated 

 into six groups. 



KEY TO GROUPS OF CONOTRACHELUS. 



a. Claws divergent, toothed, not cleft. 

 b. Thorax not sulcate, usually carinate. 



c. Femora with two teeth; costas of elytra usually interrupted. 



GROUP I. 

 cc. Femora with but one tooth; costse either entire or absent. 



d. Beak slender, much longer than head and thorax. GROUP II. 



dd. Beak rather stout, curved, scarcely longer than head and 



thorax. GROUP III. 



bb. Thorax broadly and shallowly silicate, with two low crests in front. 



GROUP IV.
