o44 THE CANADIAN ENTOMOLOGIST. 



basal lobe truncate at apex; surface very densely clothed with white 

 scales, slightly less densely around the apical irregularities ; on each side 

 of median line is a darker spot of larger size, and near the basal angles on 

 each side a smaller one. Elytra with irregular placed, not deeply 

 impressed, punctures, and some reddish tuberculiform elevations; surface 

 uneven, clothed with blackish-brown and pale-yellow small scales ; near 

 base at about middle, between the two median tubercles and near each of 

 the two subapical tubercles, is a velvety-black spot of variable size, each 

 surrounded by yellow scales. Abdomen alutaceous, sparsely punctate, 

 with broader white and narrower, elongate, yellowish scales; mesosternum 

 broadly and deeply excavated; anterior femora with an obliquely truncate- 

 emarginate, moderately broad tooth, middle and hind femora with an 

 obtuse tooth ; tibiae shorter than the femora, tarsal claws simple. Length, 

 6-7 mm. 



Palmerlee, Cochise Co., Arizona. 



A small number of this fine species was taken by beating mistletoe 

 growing on walnut, and was first discovered by Mr. H. G. Barber. 



After sending in the above description of this species, Vol. IV., pt. 4, 

 pp. 601-729 of the " Bialogia '■ was received, in which on p. 650 the 

 species was described from a single specimen from Taxpam, Vera Cruz, 

 Mexico. 



The Mexican specimen is said to have two teeth on the anterior 

 femora, while the Arizona specimens have the tooth obliquely emarginate 

 truncate. The emargination of the tooth is very likely very strong in the 

 Mexican specimen, giving the appearance of " a conspicuous additional 

 tooth on the outer edge of the larger one." 



The suture between the first and second ventral segments is more or 

 less arcuate, which makes the second segment, especially at middle, longer 

 than the third or fourth, but this is not in all specimens so well 

 pronounced. In some of our species, placed in Cryptorhynchus, the first 

 suture is not exactly straight as required, but it seems, from the variation 

 observed in this respect, that not much stress can be laid on this 

 character. 



The form is more elongate than any of the North American species. 

 This, together with the peculiar coloration and sculpture, makes it easily 

 recognizable.
