some species, unknown to us, intermediate perhaps between his 

 variegata and tortuosa ? 



What you state, quoting from Dejean, of the terminal hmule 

 being nearly lost in the lateral margin, does not seem to me of 

 so much importance as the structural character of the elytra of 

 the females. 



Mr. Alex. Agassiz told me that on examining his Missouri 

 specimens, you gave to them the name of Cicindela cuprascens^ 

 and I find that they agree in the main, though not in every par- 

 ticular, with your description, as stated in my last letter. I re- 

 memljer now that all tlie trochanters (not the hinder ones 

 only) are red or testaceous in the Missouri specimens, as they 

 are in my wliite Cicindela^ which your father gave me. The 

 latter, since reading your description, I have referred to your 

 tarsalis^ tliougli my specimen has the tarsi mutilated, so that I 

 cannot judge of their comparative length. Having only a male 

 of tliis supposed tat'salis, I do not know except from your de- 

 scription, hoAv the elytra of the female are constructed, and even 

 this seems a matter of doubt, for althono-h in your descriptive 

 catalogue, under C. Manda, you say '■'■elytra in foe minis prof unde 

 sinuata "' — in your description of tarsalis (Proc. Acad. Nat. Sc. 

 Phil., VI, p. Q^') you refer only to " one male,"' and make no 

 mention of any female, or of the structure of the female elvtra 

 of tarsalis. 



I venture to suo-o-est the followino; conclusions in regard to 

 these species, etc., though it may be rash to do so without see- 

 ing your specimen.
