densely not coarsely punctate, a smooth median carina between the eyes more or less 

 distinct. Thorax broader than long, sides arcuately narrowing to apex, which is 

 truncate, surface sparsely and coarsely punctured with tiner densely placed punctures 

 intermixed, pubescence moderately dense and ochreous. Elytra oval, about one fifth 

 longer than wide, sides slightly arcuate, apices separately rounded ; surface deeply 

 striate, punctate, intervals flat, finely punctured, clothed densely with ochreous hairs. 

 Pygidium coarsly somewhat muricately punctate, moderately densely clothed with 

 ochreous pairs, which from a denser line longitudinally at middle. Underside and 

 legs concolorous densely clothed with ochreous hairs, finer and shorter on the legs. 

 Hind femora with a blunt tooth on the inside one third from apex, hind tibiae with 

 two unequal long spurs, the outer one the longest. Length, 6 mm. 



Lake Worth, Florida. 



Six specimens, two in the Museum collection and four in coll. 

 Dietz. They were all collected by the late Ottomar Dietz. It dif- 

 fers from robinice by the toothed hind femora, uniform vestiture and 

 shorter, more oval form, in which it resembles some species of the 

 Melandrid genus Enstrophus. 



Bruchus julianus Horn. 



This gigantic Bruchus occurred quite commonly in July on Acacia 

 flexicaulis, in the large seed pods of which it undoubtedly breeds. 

 The examination of the type saved me from describing this species 

 again. Dr. Horn's types are small starved specimens 5-6 mm. long 

 while my specimens range from 8—14.5 itirn-; 12-14 mm. being the 

 average size, while only a few are of the smaller size. The deeply 

 impressed median line, the uneven slightly sulcate surface of the 

 thorax and the three dentiform elevations on each side of base of elytra 

 on which I laid some stress and which Dr. Horn did not mention in 

 his description, are only faintly indicated in the smaller specimens. 

 I have distributed specimens under the manuscript m\i\e flexicau/is. 



Bruchus arizonensis, new speJes. 



Black variegated with white and ochreous pubescence ; thorax elevated at 

 middle and with a slight median groove. Head elongate oval, constricted behind 

 the eyes, densely punctate, front carinate, around the eyes and sides of clypeus with 

 moderately long, white hairs. Antennae black, joints five to eleven suddenly broader 

 than the basal joints. Thorax slightly companulate, disk very connex in front, 

 behind the middle with two large tuberculiform elevations, these are separated by a 

 median groove which does not quite extent to the apical or basal margins, surface 

 densely clothed with white and ochreous hairs, summit of the two tubercles and the 

 declivous front of the convexity black, devoid of pubescense. Elytra as long as broad, 

 disk subdepressed, sides very slightly rounded, surface striate, stride finely punctured, 

 intervals densely punctate, flat, except the second which is slightly convex, variegated 

 with white, ochreous and black densely placed hairs, the black hairs forming a con-
