CYPHINI. 95 



rior tibiae ratlier strongly denticulate within, articular surfaces of middle 

 tibiae not ascendent. Length .26 inch ; 0.5 nnn. 



The form of this species is not unlike the preceding. The elytra are, 

 however, narrower between the humeri and the thorax, not broader at 

 base. 



This species is dedicated to my friend And. S. Fuller, to whom I am 

 indebted for this and many other species. 



Occurs from New Jersey to Montana. 



PHACEPHOLIS n. g. 



Rostrum longer than the head, slightly cuneiform, sub-quadrangular, 

 flattened above, and with a fine median groove, tip triangularly emarginate. 

 Scrobes narrow, moderately deep, well defined, slightly broader behind 

 and passing immediately beneath the eyes. Eyes round, moderately 

 prominent. Antennae sub-median, long, slender ; scape nearly attaining 

 the margin of the thorax, slender, rather suddenly clavate at tip ; funicle 

 7-jointed, longer than the scape, joints 1-2 long, the second much longer than 

 the first, 3-7 sub-equal, 7 obconical ; club elongate oval. Thorax narrower 

 in front, sides moderately arcuate, base truncate. Scutellum triangular. 

 Elytra oval, feebly emarginate at base, humeri rounded. Intercoxal process 

 of abdomen broad, truncate at tip ; second segment longer than the two fol- 

 lowing, separated from the first by a strongly arcuate suture. Anterior 

 tibiae mucronate at tip, rather strongly denticulate within. Hind tibiae 

 truncate at tip with oval, densely scaly space, articular surfaces cavernous, 

 not ascending. Body densely scaly and pilose. Claws free. 



This genus resembles the preceding in form and differs in the structure 

 of the hind tibia3 and the more distinct scutellum. The mandibles are 

 moderately prominent, exposed at base by the emargination of the genoe, 

 their surface scaly. The supports of the deciduous pieces are prominent, 

 and obliquely truncate. The deciduous pieces are long, slightly curved 

 and glabrous. I cannot satisfy myself that this genus should enter any of 

 the genera proposed by Lacordaire. 



Three species occur in this genus which differ in the form of the thorax 

 as follows : 



Thorax squarely triincate ; eyes not prominent elegans. 



Thorax obliquely truncate ; eyes prominent ; head slightly 



constricted belimd the eyes ^ obscura. 



Thorax obliquely truncate and slightly prolonged over the 



head ; eyes feebly prominent Candida. 



The first species has the thorax squarely truncate, so that it is no longer 

 on the dorsal than on the sternal side. The eyes are not prominent, and 

 the scales, although variable, of a metallic or pearly lustre. In the second 

 species the head is broadly constricted behind the eyes, the latter promi- 

 nent, and the thorax is obliquely truncate, but not sub-lobed in front, the 

 scales of the surface are luteous without lustre, with darker spaces on the
