Riley to occur in Phaseolus pauciflora. Mr. F. H. Chittenden 

 records observing fraternum in great numbers on the leaves of two 

 species or varieties of Lespedeza in July and August. 



59. A. jequabile n. sp.— Moderately robust, black, pubescent. Beak about 

 as in griseam, but a little more shining in the female. First antennal joint sub- 

 equal to the next two, third a little longer than the fourth, much shorter than 

 the two following united. Front not sulcate. Prothorax constricted before the 

 base, which is not wider than the middle. Elytra a little wider just behind the 

 middle; intervals moderately convex. Length 1.6-1.9 mm. ; .Of55-.08 inch. 



H<(.b. — Arizona, Lower California (La Chuparosa). 



This species so nearly resembles the preceding that a more detailed 

 description is not deemed necessary. It is a little smaller, and is 

 probably never in the least aeneous. I have selected as the types a 

 series {% 9 ) iu the collection of the California Academy of Sciences 

 from Lower California, and with them have i)laced a female from 

 Arizona, in Dr. Horn's collection, which agrees in all essentials. 



60. A. dolosiiiii n. sp. — Moderately elongate but not slender, black, pubes- 

 cent. Beak ( % ) moderately stout, a little shorter than the head and thorax, 

 dilated a little behind the middle; finely sculptured in basal three-fourths; sides 

 rather coarsely and irregularly punctate and pubescent; tip shining; ( 9 ) longer 

 than the head and thorax, more slender, slightly dilated about one-third from 

 the base; surface dull throughout; punctuation finer but strong, uniform and 

 moderately close. First joint of antennae as long as the three following in the 



O, a little shorter iu the % , second joint reaching the eye. Front flat or vaguely 

 sulcate; eyes moderately prominent. Prothorax as long as wide, widest behind 

 the middle, sinuate before the base; surface closely, moderately, coarsely punc- 

 tate, with an elongate basal fovea. Elytra a little more than one-half longer 

 than wide; humeri not very prominent; sides nearly straight and diverging to 

 behind the middle, thence rounding to tip ; intervals about twice as wide as the 

 striffi and nearly flat. Punctuation beneath close, not very coarse ; legs rather 

 stout; claws with a strong acute tooth. Length 2.5 mm. ; .10 inch. 



% . Sutural tips narrowly rounded ; middle and hind tibise with a rather short 

 mucro which is subangulate below. 



9 . Sutural tips not rounded ; tibife unarmed. 



Hab. — Arizona. 



Taken by Mr. Wickham at Williams, and distributed in various 

 collections. A specimen in Mr. Wickham's collection is labelled as 

 beino- found on " Locust." The species is evidently related, but not 

 especially closely, to the eastern nigrain, which has similar habits. 

 Some variation in the length and basal sinuation of the thorax and 

 in the width of the elytral intervals has been noticed. 



61. A. carinirostruiii n. sp.— Black, pubescence well marked Beak (% ) 

 a little shorter than the head and prothorax, rather stout, feebly curved, scarcely 

 dilated, somewhat shining and pubescent nearly to the tip ; ( 9 ) longer than the
