AND ClCINDELA 3 



4 Hind tarsi ( 9 ) shorter, about as long as the tibiae; prothorax narrow, 

 as long as wide even in the female, the base more transverse and 

 more broadly and feebly bisinuate; surface with the anastomosing 

 lines rather distinct, the minute punctulation evident. Length 

 (d 71 9 ) 14.0-15.5 mm.; width 5.0-5.5 mm. Oregon and Washington 

 State. Rather abundant audouini Rche. 



Hind tarsi ( 9 ) much longer than the tibiae 5 



5 Body small and notably slender, of a facies and in sculpture nearly 

 as in audouini but with shorter and more slender antennae; prothorax 

 nearly similar, narrow, as long as wide and nearly similar in the 

 two sexes as in audouini. Length (cf 9 ) 12.8-13.2 mm.; width 

 4.4-4.8 mm. Oregon parvulus Csy. 



Body large, very stout and massive; antennae notably short in the female; 

 prothorax much larger and broader than in the two preceding, wider 

 than long, the base transverse and barely perceptibly bisinuate, the 

 surface opaculate and with fine anastomosing lines and minute 

 punctulation as in audouini; elytra broad, rather feebly convex 

 medially, widest at the middle and with the punctures more evenly 

 circular and much deeper than in any other of the group, perforate, 

 the interspaces rather shining, only feebly alutaceous and without 

 trace of minute punctulation. Length ( 9 ) 17.0 mm. ; width 6.3 mm. 

 Northern California (without record of more definite locality). 



rugipennis n. sp. 



6 Body rather shorter, relatively broader and moderately convex, the 

 hind tarsi much longer than the tibiae in both sexes; prothorax 

 relatively larger and broader than in audouini or parvulus, though 

 nearly similarly sculptured ; base transverse and very feebly bisinuate ; 

 elytra widest at the middle, the punctures rather small and well 

 separated internally and also rather more than usually obsolete 

 near the humeri, which are distinctly convexo-declivous as usual; 

 interspersed minute punctulation very obvious. Length (cf 9 ) 

 13.8-15.8 mm.; width 5.3-5.9 mm. California (Del Norte Co.), 

 Nunenmacher humeroplanatus \V. Horn 



Body larger, more elongate and more convex, relatively not so ventricose 

 as in audouini, the prothorax much larger, very little wider than long, 

 . opaculate, the fine anastomosing lines evident; base transverse, 

 broadly and very feebly bisinuate; elytra one-half longer than wide, 

 barely one-half wider than the prothorax, widest a little behind the 

 middle; surface very convex, with the micro-granulation strong and 

 more conspicuous than in any other species, almost obliterating the 

 minute punctulation, the punctures rather coarse and confused but 

 unusually shallow and generally with their bottom finely lineiform 

 by transverse light, the scattered foveae very inconspicuous, much 

 less evident than in the preceding; hind tarsi but little longer than 

 the tibiae. Length (cf ) 16.0 mm.; width 5.9 mm. California (Shasta 

 Retreat, Siskiyou Co.) solidulus n. sp. 



7 Form and habitus radically different from any of the preceding, due 

 to the very elongate cylindric outline ; front nearly smooth and without 

 punctures between the foveee; prothorax about as long as wide, 

 sculptured nearly as in audouini, the transverse subbasal groove
