CICINDELID.E 23 



moderate, the foveae evident but not very conspicuous; side margins 

 well reflexed, especially toward the humeri. Length (9 ) 15.8 mm.; 

 width 6.0 mm. California (Wawona, Mariposa Co.). 



sinuosus n. subsp. 



Female stout, nearly as in horni, the male more slender than in that form . 6 

 6 Female stout, subopaque, with more shining elytra as usual; head 

 large, but narrower than the prothorax, rather strongly rugose, the 

 anterior punctures obscured; labrum bisinuate, the lobe rather 

 prominent, large, broadly truncate at tip; antennae rather long, 

 slender, not paler distally; prothorax moderately obtrapezoidal,the 

 sides oblique at base, which the margin attains, fully a fourth wider 

 than long; surface with fine anastomosing lines, rugulose apically and 

 basally, the base distinctly bisinuate; elytra nearly one-half longer 

 than wide, the sides evenly arcuate, the apex gradually acute; side 

 margins fine; humeri rather evident; punctures coarse, deep, sepa- 

 rated suturally, the granules distinct, irregular. Male smaller and 

 much less stout but otherwise nearly similar to the female, the ante- 

 rior tarsi well dilated but with the third joint smaller than the second, 

 though wider than long. Length (c?) 14.0 mm., (9) 15.5 mm.; 

 width (cf) 5.6-5.8 mm,. (9) 6.4 mm. California (Tuolumne Co.). 



Four examples punctatus n. subsp. 



Female large and very stout, the lustre as in the preceding; head moderate, 

 much narrower than the prothorax, rugulose throughout, the an- 

 terior punctures obliterated; labral lobe very prominent, narrowly 

 truncate; antennse slender, rather long; prothorax large, much less 

 transverse than in horni, moderately obtrapezoidal, the sides very 

 rapidly rounding inward basally, less than a fourth wider than long; 

 surface as in the preceding, the base moderately bisinuate; side 

 margins not attaining the base; elytra much inflated, less than one- 

 half longer than wide, very nearly one-half wider than the prothorax, 

 widest at the middle, the converging sides thence straighter basally, 

 gradually very arcuate and converging posteriorly; humeri narrow at 

 base but rather evident; punctures very coarse and close throughout, 

 deep but broadly impressed, the granules small though evident; 

 legs rather long and slender. Length (9 ) 15.3 mm.; width 6.8 mm. 

 California (Mariposa Co., June 18, 1914) farctus n. subsp. 



The three examples above included under the name horni seem to 

 satisfy the original description very well, although the prothorax is 

 more transverse than might be inferred from LeConte's description.* 



* The very numerous forms characterized in the horni group, are all local and con- 

 fined to various valleys and heights in the Mariposa-Ttiolumne region of the Sierras. 

 They form an extremely difficult study. A large number of them are easily recog- 

 nizable, but I am free to admit that some others can only be identified certainly by 



% 

 actual comparison with the types, and even then only after some experience has been 



gained in the study of the genus. In publishing them therefore, it is with a feeling 

 that I shall not be thanked by those who have to rely chiefly upon descriptions. But 

 the types are accessible to all those who care to view them, and I trust that this will be 

 the case as long as they exist. It is one of my chief enjoyments laboriously to work
