28 MEMOIRS ON THE COLEOPTERA 



almost exactly as in the scutellaris group; it evidently could not 

 interbreed with any other species. 



In the formosa group, formosa, generosa and manitoba are mani- 

 festly slight varietal forms of a single species, but luxuriosa is 

 constantly different in the very much narrower markings, though 

 having a similar stout outline; it is a distinct subspecies and I 

 have recently received additional material from Yuma in north- 

 eastern Colorado. Admiscens is a very remarkable species, having 

 the broad and characteristic markings of the formosa group, with a 

 short labrum, exactly as in the tranquebarica group; it might there- 

 fore be considered either an annectent form between the two groups, 

 as a separate group by itself or as an aberrant species in the tran- 

 quebarica group; the last seems to be the best course to recommend. 



In the tranquebarica group the distinct species are: tranque- 

 barica with synonyms horiconensis and turbulenta and subspecies 

 vibex, kirbyi, wichitana, crinifrons -this being the same as minor 

 Leng, of the list, which however was not formally defined, being 

 merely mentioned in the text without authorship or description, 

 lassenica and viridissima; moapana, plutonica, bellissima and 

 diffracta. Viridissima occurs under two forms, one having a nearly 

 complete humeral lunule and the middle band extending to the 

 sides, occurring in Kern Co., California, the other with only the 

 posterior inner part of the lunule and the middle band widely iso- 

 lated from the margin, occurring in Tulare Co. 



In the repanda group the forms near ancocisconensis require 

 revision. Mr. Harris was kind enough to give me a typical speci- 

 men of that species, taken in the type locality, and this proves to 

 be the key to the situation. I at first thought that dowiana was 

 identical, but, as Mr. Harris wrote me that in his opinion it was 

 not the same, a more careful observation shows me that, although 

 having likewise a notably elongate form of body, it is probably 

 a distinct and still more slender modification. My two examples of 

 dowiana are both females but are, if anything, narrower than the 

 single male of ancocisconensis at hand. The following are two very 

 well differentiated subspecies of ancocisconensis: 



Cicindela ancocisconensis ssp. carolinae nov. Smaller and still nar- 

 rower than ancocisconensis, similar in color, markings and sculpture, except 

 that the coarser elytral punctures toward base are almost obsolete, the 

 humeral lunule not quite so long and the prothorax much shorter and
