CUCUJID.E 127 



generic designation and would suggest the name Charaphlceus 

 (n. subgen.) for them, with the type Lcemophlceus convexulus Lee. 

 The species described by Dr. Sharp under the name Lamophlceus 

 immersus (Biol. Cent. Amer., Vol. II, Pt. i, p. 520; PI. XVI, fig. 18) 

 also constitutes a section radically different from the normal forms 

 of the genus in the special habitus produced by the peculiar sub- 

 quadrate outline of the prothorax, and it may also possibly be dis- 

 tinguished by 4-jointed tarsi, as suspected by the author. I would 

 suggest that it form the type of a distinct subgenus under the name 

 Phlceolaemus (n. subgen.). 



Silvanophlceus Sharp 



The type of this genus is the European Lamophlceus testaceus 

 Fabr. The genus differs from Lcemophloeus in many ways. The 

 elongate parallel and very depressed configuration and long exposed 

 terminal segment of the abdomen, give the species a very different 

 general aspect, and to this should be added the entirely closed an- 

 terior acetabula; the hind tarsi are 4-jointed in the male, as in 

 Lcemophlceus, but the second joint is less elongate. The epistomal 

 suture is distinct in all the species, which will distinguish them readily 

 from any Cryptolestes even the unusually elongate forms of the 

 latter genus. The species in my collection may very easily be 

 known among themselves by the following characters: 



Head and sides of the prothorax rather convex, the latter densely micro- 

 reticulate and dullish in lustre, the head above and beneath closely 

 and strongly punctured. Body elongate, the sides somewhat ar- 

 cuate; male with the eyes slightly before the base, moderately large 

 and prominent; antennae three-fourths as long as the body, rather 

 slender, filiform, the basal joint stout, oval, the next three mutually 

 subequal and shorter than the following joints; prothorax subquad- 

 rate, the sides feebly converging from the apex, where the angles are 

 abruptly denticuliform and prominent, the basal angles sharp but 

 not at all prominent; surface finely, not densely punctate, more 

 strongly and closely outside of the strong sublateral furrows; elytra 

 wider than the prothorax, the sides feebly arcuate and slightly 

 converging from near the middle to the subcircularly obtuse apex; 

 surface finely, rather closely, confusedly punctate, with two fine 

 approximate sublateral striae on each, and a coarsely impressed sub- 

 sutural stria vanishing before the middle; last ventral segment only 

 slightly longer than the preceding. Female nearly like the male 

 but with still less exposed apex of the abdomen and less elongate 

 antennae. Length (d 71 9 ) 2.0-2.9 mm.; width 0.63-0.73 mm.
