on cacli side of the elytra. The legs and antennae are always red, 

 thongli 2 or 3 of tlie apical joints of the latter are sometimes somewhat 

 infuscated. 



It differs from the preceding in the elytra being narrower, without 

 the uneven surface described above, in their different clothing which is 

 much less developed, so that these generally appear nearly bare and shin- 

 ing except for minute setae, and the pronotum also is much less closel}^ 

 covered. This species would be difficult to distinguish from worn exam- 

 ples of various other more obscure members of the genus, were it not 

 for tlie similarity of the rostrum in both sexes, so that while it never 

 resembles the female of any other species, it differs from most males by 

 the greater length or more definite character of this organ. Length, 

 male and female, 1.6-J mm. 



Tliis species is mainly described from a series of lo exam- 

 ])les given me by !Mr. Swezey some years ago, wliidi wci-c 

 cleaned and monnted by me when newly captnred. Others 

 taken with these ^vere dissected at the same time. In a<l<liTion 

 to these. I have nsed well-momited examples taken casnally at 

 an earlier date without note of food-plant, these having i-e- 

 mained mniamed, as l)eing donbtfnlly distinct fi-om some de- 

 sei'ibe(l species. I have more snperticially examined a series of 

 30 examples monnted on ])oints and collected by Air. d. {'.

Proterhinus fuscicolor n. sp. 



.\ dark pitchy brown or jiitchy black species, the pronotum generally, 

 the head often and sometimes the base of the elytra with an obscure red 

 tint. .\n elongate species of the group of fcrn(}iincus cf^itrclits and

Antennae appearing ratlier sliort comiiared with the lengtli of tlie 

 whole insect, between two-thirds and tliree-fourths the length of the 

 elytra, red, the club joints often' ai)i)earing more or less dark. Rostrtnn 

 of the male shorter ahmg the sides than the width, of the female elon- 

 gate, not polished l)ut rugulose, so that the punctate grooved lines are 

 obscured, or more or less effaced. Pronotum narrow compared with 

 the elytra, conspicuously and definitely narrowed in front, the golden 

 clothing not dense, so th;it tlie rougli scn]])tin-e is easily seen, the sides
