SPONDYLID/E 219 



Prothorax not so short and without trace of impressions or in any way 

 modified median line, the basal joint of the antennae stouter and more 

 rounded 4 



4 Form stout, dullish black; pubescence of the front, mandibles and 

 entire under surface coarse, yellowish and conspicuous, rather dense 

 beneath; head slightly narrower than the prothorax, densely and 

 strongly punctured throughout, more coarsely on the median parts 

 of the vertex than elsewhere and with a shining irregular unimpressed 

 and punctureless median line from the line of the eyes to the base; 

 prothorax nearly two-fifths wider than long, the outline as in the 

 preceding, the surface even, the punctures not so large as those of 

 the head and much shallower, moderately close, somewhat uneven 

 in distribution; elytra a fifth wider than the prothorax, nearly as 

 in the preceding but less finely, less closely and more vernacularly 

 punctate and with the raised lines feebler; metasternal impression 

 shallower, with a fine and impunctate medial subcariniform line 

 throughout. Length 17.0 mm.; width 5.8 mm. Washington State. 

 Female wanting robustula n. sp. 



Form less stout, more elongate, more shining and deeper black as a rule, 

 the yellowish-cinereous pubescence of the head and mandibles abun- 

 dant, that of the under surface long, close, longer but finer than in 

 robustula; head coarsely, deeply, very densely punctate throughout, 

 much smaller than in the preceding and distinctly narrower than the 

 prothorax, the median line not modified; prothorax much longer, 

 not quite a fourth wider than long, widest and more strongly rounded 

 at the sides nearer the apex; surface even, the punctures not so large 

 or dense as those of the head, irregular in distribution, deeper than 

 in robustula; elytra a fourth wider than the prothorax, nearly three- 

 fourths longer than wide, subevenly, deeply, very closely and mod- 

 erately coarsely punctured; two raised lines on each distinct, the 

 outer obsolescent; metasternum nearly as in the preceding, except 

 that the impression is less diffused, smaller and deeper, the fine 

 smooth dividing line similar. Female stouter, with coarser sculpture 

 and much less distinct elytral lines than in the male. Length 14.0- 

 16.5 mm.; width 4.8-5.9 mm. California subpubescens n. sp. 



5 Body narrow, much more elongate than in any of the preceding, still 

 more shining than in subpubescens and similarly very deep black; 

 pubescence sparse above, short and moderately abundant beneath, 

 everywhere dusky and inconspicuous; head very nearly as wide as 

 the prothorax, the punctures moderately coarse, dense anteriorly, 

 slightly coarser and widely scattered from before the middle to the 

 base, the median line not modified; antennae thick, joints 8-10 on the 

 compressed sides but just visibly longer than wide; prothorax long, 

 between a fourth and fifth wider than long, widest and with broadly 

 rounded and subparallel sides anteriorly, the base relatively more nar- 

 rowed than usual, the sides just before the basal margin just visibly 

 subsinuate, strongly, irregularly punctate, the median line broadly 

 impunctate basally; elytra nearly a third wider than the prothorax, 

 three-fourths longer than wide, densely punctured, the two inner
