on each side of the eh-tra. The legs and antennae are always red, 

 though 2 or 3 of the 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 closely 

 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 the 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, 1.6-2 mm. 



This species is mainly described from a series of 13 exam- 

 ples given me bv jMr. Swezev some years ago, which yvwc 

 cleaned and monnted by me when newly captnred. Others 

 taken with these were dissected at the same time. In addition 

 to these, I have nsed well-monnted examples taken casnally at 

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

 mained nnnamed, as being donbtfnlly distinct from some de- 

 scribed species. I have more superficially examined a series of 

 30 examples monnted on points and collected hy ^Nfr. J. C 

 Bridwell. 



IIab. Oahu, in the mountains near Honolulu. This spe- 

 cies was found by Mr. Swezey to have the abnormal habit of 

 mining the leaves of Broussai.sia. ^Ir. Bridwell's examjdes 

 wore collected on Kaumuahona, July 23, 1916. 



Proterhinus fuscicolor n. sp. 



A dark pitchy brown or pitchy black species, the pronotum generally, 

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

 tint. An elongate species of the group of fcrntgtitcus epitretits and 

 detritus, but very distinct by its sordid color. 



Antennae appearing rather short compared with the length of the 

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

 elytra, red, the club joints often appearing more or less dark. Rostrum 

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

 gate, not polished but rugulo.se, so that the punctate grooved lines are 

 nliscured, or more ov less effaced. Pronotum narrow compared with 

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

 clothing not dense, so that the rough sculpture is easily seen, the sides
