spicuous fascia at middle, irregular in outline, broad at sides and interrupted on the 

 disk at the first and third stria;. Pygidium convex at apex, densely putescent with 

 white hairs, a transverse line of black hairs at middle. Legs piceous, tibia; paler at 

 apex, hind femur on the inner side near apex with a small tooth. Length, 3.5 mm. 



Pinal Mountains, Arizona. 



One specimen from Mr. Chas. Palm in the Museum of the Brook- 

 lyn Institute. 



This species does not fit in any of the groups proposed by Dr. 

 Horn, it is best placed near mimus, having the thorax similarly elevated 

 and grooved, but has only ore small tooth on the hind femur. In the 

 specimen from the above named locality the pubescence on the apex 

 of the pygidium is rubbed off, in another specimen from Yuma 

 Co., Ariz., in my possession there are two short black lines on 

 each side of the apex as in prosopis and the black transverse line at 

 middle is only faintly indicated and the hind femora and tibiae are 

 more reddish. 



Bruchus gibbithorax, new species. 



Black, thorax and elytra densely clothed with white and ochreous hairs, black 

 hairs forming large patches and lines on the elytra, thorax gibbous in front. Head 

 elongate oval, clothed with white hairs concealing the surface sculpture, front cari- 

 nate ; antennje black, joints five to eleven much broader than the preceding. Thorax 

 convex, gibbous in front, densely clothed with ochreous and white hairs, an antescu- 

 tellar spot of white hairs, front of the gibbosity black. Elytra about as broad as 

 long, sides very slightly arcuate, disk striate, variegated with black, ochreous and 

 white hairs ; the ochreous and white hairs forming the general pubescence, the black 

 forming distinct marks as follows : a large spot at humeral angle, a large broad fascia 

 about middle, from the side margin to the third stria and a large spot at apex, be- 

 tween the humeral spot and the median fascia is a smaller spot situated on the second 

 stria and a still smaller on the fourth stria, between the median fascia and apical spot 

 is also a smaller one on the second stria, these two smaller spots situated on the sec- 

 ond stria are connected by a line of white hairs. Pygidium slightly convex, densely 

 clothed with white hairs. Underside densely pubescent with white hairs, concealing 

 the surface sculpture. Femora reddish, tarsi black ; hind femora with a small tooth- 



Pinal Mountains, Arizona. 



Two specimens from Mr. Chas. Palm in the Museum of the Brook- 

 lyn Institute. 



This species can not be compared with any of our North American 

 Bruchus ; it is near arizo/iensis above described, but is very much 

 smaller, the markings though similar are better defined, the median 

 line and the two tuberculiform elevations of the thorax so prominent 

 in arizonensis are not present here.
