ClCINDELIDyE AND CARABID^E 25 



Cicindela venusta ssp. gracilenta nov. Similar to venusta and versnta 

 but much more slender and smaller in size, the coloration and maculation 

 above and beneath as in the latter; hairs on the front, femora and thoracic 

 flanks coarser and whiter than in venusta; prothorax much narrower and 

 less transverse, the head smaller. Length (c?) 11.7 mm.; width 4.2 mm. 

 Montana. 



The hind tarsi have the joints pale toward their bases in a way 

 not noticeable in either of the other forms mentioned, and the 

 porrect white spinules at their apices are relatively longer and more 

 conspicuous. 



The following species presents a singular combination of char- 

 acters and is distinctly isolated : 



Cicindela admiscens n. sp. Form and ornamentation nearly as in 

 venusta, the inner prolongation of the humeral lunule being more oblique as 

 a rule, the ground color above more obscure cupreous-brown; pubescence 

 throughout less abundant, the sculpture a little finer; labrum differing 

 remarkably, being short and transverse as in the tranqnebarica group, 

 the three teeth moderate but distinct; prothorax relatively smaller, 

 narrower than the head, similarly sulcate; elytra with very broad white 

 marking, almost exactly as in venusta throughout; under surface colored 

 as in versuta; legs slender. Length (o 71 9 ) 13.0-15.0 mm.; width 4.9-5.5 

 mm. New Mexico (Jemez Springs). 



A large series of this species was sent to me recently by Mr. 

 Woodgate. I mistook it at first for venusta, but the radically dif- 

 ferent labrum, which is similar in the sexes, prevented any associa- 

 tion with that species ; in fact some doubt might arise as to whether 

 it should not be considered an aberrant member of the next group, 

 but in my opinion it is correctly assigned to the formosa group. 



13 In the tranquebarica (vulgaris) group the species in general are 

 of rather larger size than those of the repanda group, and, as before 

 stated, segregate themselves into four widely distinct types. In the 

 tranquebarica subgroup the various forms are closely allied among 

 themselves, but include two subtypes, the first having the oblique 

 inner part of the middle band short as in tranquebarica, hori- 

 conensis and the two following, and the second having this oblique 

 arm long as in vibex and kirbyi. 



Cicindela tranquebarica ssp. turbulenta nov. Similar in general to 

 tranquebarica but rather larger and much stouter, not black or blackish 

 but dull and deep red-brown, more shining and red at the outer elytral 

 margins; three labral teeth very strong, not on a median projecting part
