22 MEMOIRS ON THE COLEOPTERA 



prothorax barely (cf ) to distinctly (9 ) narrower than the head, a third 

 to two-fifths wider than long, finely, densely sculptured; elytra marked 

 throughout nearly as in tranquebarica, with the punctures rather small 

 and not close-set, though more distinct than in that species, more ab- 

 breviated in form and with the fine prolongation of the humeral lunule 

 less oblique; legs and tarsi more slender; tip of the abdomen ( 9 ) differing 

 in being canalicularly impressed apically. Length (cf 9 ) 11.8-12.0 mm.; 

 width 4.9-5.2 mm. Kansas, Knaus. Four specimens. 



This may prove to be more properly a subspecies of tranquebarica, 

 but it differs in its very much smaller size and in other ways as 

 detailed above. 



Cicindela lassenica n. sp. General form and ornamentation 

 nearly as in tranquebarica but differing remarkably in coloration, deep 

 black throughout above, beneath and on the legs, without trace of metallic 

 coloration at any point, very dull in lustre above, rather shining beneath; 

 head (cf ) moderate, with long sparse hairs, which are dense on the frontal 

 umbo; labrum rather short, tridentate medially; prothorax large, trans- 

 versely quadrate, fully one-half wider than long and as wide as the head, 

 densely sculptured; elytra oblong, parallel, with less arcuate sides than 

 in tranquebarica but with identical maculation, the middle band similar, 

 the posterior arm short and not long as it is in vibex and kirbyi; punctures 

 fine, feeble, close-set and strongly granuliferous, the ground very opaque; 

 under surface moderately hairy toward the sides, coarsely on the pro- 

 pleura; legs moderate. Length (cf) 13.5 mm.; width 5.3 mm. Cali- 

 fornia (without further indication of locality). 



Though similar to tranquebarica in its markings, I hardly think 

 that the taxonomic value of this form can be less than specific. 



Cicindela moapana n. sp. Habitus similar to that of r-ibex and 

 kirbyi but larger and with more elongate and larger elytra, dark coppery- 

 brown, the head and pronotum a little brighter, cupreous, the bottom of 

 the deep sulci blue; sides of the elytra smoother, more shining and rather 

 bright coppery-red; under surface more shining, blue-green, the side- 

 pieces of all the sterna bright coppery; legs cupreous-red; head (9 ) well 

 developed, with sparse white hairs, which are dense on the frontal umbo; 

 labrum short, pale, with black anterior edge, acutely tridentate; prothorax 

 equal in width to the head, transverse, slightly narrowed from apex to 

 base, sculptured densely as usual; elytra large, more than one-half 

 longer than wide, subparallel, with feebly arcuate sides and with almost 

 circularly rounded apex in posterior third, the humeral lunule as in vibex, 

 the apical as in kirbyi but much broader, the median band unlike any- 

 thing else in the group, consisting solely of the posterior arm as seen in 

 kirbyi, the portion from the angle to the sides wholly obsolete and without 

 the faintest suggestion caused by irregularity of sculpture, the latter 

 being perfectly even over the place which is occupied by the transverse 

 part of the band in the allied species; legs rather long, the hind tarsi short, 

 not as long as the tibiae. Length ( 9 ) 15.0 mm.; width 6.2 mm. Nevada 

 (McGill, White Pine Co., 6500 feet).
