NO. H.S7. NORTH AMERICAN DIGGER WASPS— FERNALD. 861 



examples taken at Chokoloskee, Florida; New Orleans, Louisiana; 

 Dallas, Texas; and Saussure reports it from Orizaba, Jalapa, and 

 Cordoba, Mexico. These localities indicate that it lives in the Tran- 

 sition, Upper Austral and Lower Austral zones, the Mexican specimens 

 coming' from quite hi^ifh altitudes. 



Li the Harris collection now at the Boston Society of Natural His- 

 tor}' are three specimens of this insect, each bearing- the number "72." 

 Harris's manuscript record book corresponding to these numbers reads 

 as follows: "72. Ammophila apicalis, 8. letter. Sphex probably not 

 a true Ammophila. on umbellate firs. July 25, 1825. large and small 

 & Dublin N. H. on do. July 22, 1835. Camb. on Asclepias Aug. 1, 

 1838." I am informed by Mr. Samuel Henshaw that the expression 

 '"S. letter," probably means that Harris got the name from Say. 

 There is therefore no longer any question that the reference to Harris 

 for this species is correct. As the name is a nomen nudum, however, 

 it can not hold as the name of this insect, and several of the more 

 recent writers have adopted 'Lepe\etiev''ii j>hilade/j?hicum as the correct 

 name. With this view I am not at present able to agree, as Lepe- 

 letier's description fails to correspond entirely with this insect, and 

 the type is lost. Kohl also seems now to doubt the identity of Lepele- 

 tier's insect with the one under consideration, as he writes me: " Wahr- 

 scheinlich ist Sph. philadelphicus Lepeletiers (/ar keine Isodontia." 



The specific name ajncaUs Smith would be the next available one 

 for this species, but unfortunately Smith had used this name for 

 another species of the genus nine pages earlier in the same article, 

 thus excluding it from application here in accordance with the law of 

 place prior it}'. 



As there have been no other names applied to this insect so far as 

 is known, a new name becomes necessary, and I have selected harrisi 

 as being an appropriate one under the circumstances. 



The prey of Chlorion harrisi consists of Tree Crickets {(Ecanthus)^ 

 but whether of more than one species is not recorded. It is illustrated 

 as figure 1, Plate VII, of the Insect Book.
