NOTE ON PHYTOBIUS. 



BY E. A. SCHWARZ. 



At a previous meeting of our Society (see Proceed. I, No. 2, 

 pp. 75, 76) I exhibited a species of the Curculionid genus 

 Phytobius found near Detroit, Mich. From a comparison with 

 European specimens, which were given me as Ph. velatus, I 

 had come to the conclusion that our species was different from 

 that described by Dr. LeConte (Rhynchophora, p. 281) as 

 Ph. velatus. Subsequently I discovered that my European 

 specimens were incorrectly named, and that the specimens 

 from Michigan perfectly agreed with Thomson's excellent 

 description of that species (Scand. Col. VII, p. 232). More 

 over, Dr. Horn upon a recent visit to Cambridge found that 

 the Michigan specimens were specifically identical with the 

 unique type in the L,eConte collection. 



Phytobius velatus is readily known among our Ceutorhynchini 

 from its singular resemblance to the genus Bagous, which is 

 not only exhibited in the structure of the tarsi but also in the 

 form of the thorax which is almost square, and with the 

 tubercles but feebly developed. In the best preserved speci 

 mens before me the median line and the sides of the thorax t as 

 well as the suture and the sides of the elytra are covered with 

 sulphur-yellow scales, but this striking color is of an evanes 

 cent nature, and in most -specimens these scales are dirty 

 greenish-yellow. 



A- second North American Ceutorhynchid with narrow tarsi 

 and very long claw-joint, and which must be referred to the 

 genus Phytobius as defined by LeConte, is known to me and 

 may be described as follows : 



Phytobius griseomicans n. sp. Form of body as in Ceutorhynchus 

 rapce, but transversely more convex and more rounded behind. Opaque, 

 general color pitchy black, antennae and legs, excepting the knees, red 

 dish-yellow, apical edge of elytra reddish ; upper surface densely covered 

 with small closely-applied scales which form a water-proof covering, 

 under side clothed with larger and less densely placed scales. 



Beak a little longer than the thorax, gently curved, cylindrical, densely, 

 finely punctulate, scales on upper side small and greyish, those on sides 

 and under side larger and white. Antennae inserted at the middle of the
