 same name was not accessible to him. 



724 (8856). PHYTOBIUS VELATUS Beck, Beitr. zur Bseirsch Ins. Faun.. 

 1817, 20. 



Elongate-oval. Black, clothed above with greenish-yellow scales, more 

 dense on median line and sides of thorax and suture and sides of elytra; 

 beneath with larger grayish-yellow scales; antennae and legs reddish-brown, 

 knees dusky. Beak short, stout, slightly longer than head, punctured and 

 scaly towards base. Thorax slightly wider at base than long, lateral 

 tubercles small, rounded; disc rather coarsely and densely punctured, its 

 dorsal channel wide, entire. Elytra one-third wider at base than thorax, 

 sides gradually narrowed from the shoulders; striae deep, wide, punctate; 

 intervals convex, rugose. Tarsi with swimming hairs. Length 2.2 2.5 mm. 



A common European species taken in this country in Massa- 

 chusetts, near Detroit, Mich., in Dane Co., Wisconsin, and on 

 Vancouver Island. Its habits are aquatic, the adults ovipositing 

 on pondweed (Potaniogeton). It is also found in all stages under 

 water on the filiform leaves of the spiked water-milfoil, Myrio- 

 p]ii/Uui si>ic(ttu)tt L., a common European and American deep 

 fresh-water plant. "The larvae are covered with a viscous liquid 

 insoluble in water; when about to pupate the body is covered 

 with a large quantity of gum exuded from the anus. This 

 hardens into a spherical cocoon which is firmly attached to a 

 branch of the plant, the larva? remaining constantly under water, 

 the adults only coming to shore to hibernate under debris in 

 very wet places." (Perm.) Schwarz records finding in the fall, 

 near Detroit, Mich., a number of specimens hibernating in moist 

 ground on the banks of the Riviere Rouge, which at that locality 

 is filled with Myrio})lii/Uuiii. The beetle probably occurs in this 

 country Avherever this milfoil grows and should be sought for 

 by collectors as American examples are very scarce. Redescribed 

 bv Dietz under the name P. Iccontei.

Tribe XXI. CRYPTORHYNCHINI. 



A large assemblage of rather broad, robust, often strongly 

 sculptured species varying greatly in appearance and structural 

 detail. In addition to the characters given in the tribal key, p. 

 140, we find the funicle 7- rarely 6-jointed, club annulated; 

 tibiae armed with a strong hook at tip, their articular surface 

 oblique; tarsi dilated with the third joint bilobed ; second and 

 third ventral segments somewhat angulated at the sides and 

 variable in length ; upper surface often clothed with scales or 

 sc(u> or both, arranged in conspicuous designs.
