218 MEMOIRS ON THE COLEOPTERA 



Subfamily SPONDYLIN^:. 



Spondylis Fabr. 



The species of this genus, while strikingly uniform in general 

 appearance, prove to be rather numerous and amply well defined. 

 Upiformis Mann., and laticeps Lee., the former from southern 

 Alaska and the latter from Lake Superior, are both unknown t3 me 

 but are undoubtedly distinct from any of the five here described; 

 upiformis is rather small and slender, the type being 13 by 4.5 

 mm. in size, which is all the useful information derivable from the 

 original diagnosis, while laticeps is unusually large, with the head 

 as wide as the prothorax, the latter subcarinate medially; the length 

 of the type is 18.7 mm. The body is a little stouter and larger in 

 the female than in the male, with distinctly smaller head and 

 slightly shorter antennae, but differs very little otherwise. The 

 range of the genus is from the palaearctic faunal regions, through 

 the western parts of subarctic North America; it does not occur in 

 the American Atlantic regions. The western and Sonoran species 

 in my collection may be known as follows from the male except in 

 basalis: 



Sides of the prothorax oblique basally but not or scarcely at all sinuate, 

 the base never notably prolonged or subtubulate; anterior parts 



only a little narrower than the elytra 2 



Sides of the prothorax becoming sinuate basally, the basal part prolonged 

 and notably subtubulate; anterior parts much narrower than the 



elytra 6 



2 Antennae longer, extending distinctly beyond the base of the elytra. . 3 



Antennae notably short, not extending beyond the elytral base 5 



3 Prothorax bi-impressed on the disk and with a sharply denned and 

 subprominent median impunctate line, not quite attaining the apex. 

 Body stout, moderately shining and black, nearly glabrous above, 

 the under surface with short and moderately close, fuscous and in- 

 conspicuous hairs; head just visibly narrower than the prothorax, 

 strongly, closely punctate, less strongly and very sparsely toward 

 base, the median line not modified, except finely and feebly impressed, 

 obsolescently so basally; basal joint of the antennae arcuately sub- 

 cylindric; prothorax transverse, one-half wider than long, widest 

 and broadly rounded at the sides well before the middle, the im- 

 pressions shallow, irregular, symmetrically placed; elytra parallel, 

 obtuse at apex, three-fifths longer than wide, less coarsely punctate 

 than usual, .the punctures very dense, the two inner discal lines 

 strong, the outer fine and feeble; metasternal impression large, 

 rounded, the polished bottom of the impression broadly fusiform. 

 Length 16.0 mm.; width 5.6 mm. Utah. Female wanting.
