ClCINDELID.E AND CARABID^ 3! 



oregona in my collection the under surface is as described above, 

 without trace of coppery sternal side-pieces, while in every example 

 of a still larger series of guttifera these side-pieces are cupreous; 

 there is no exception in either case. Dejean mentions the latter 

 form of coloration in his description of 12-guttata, which occurs only 

 in the Atlantic regions, and this is confirmed by my material. 

 Oregona has been very generally misunderstood; it is a mountain 

 species, confined to the Sierra regions; Colorado and Kansas 

 examples are specifically different and the New Mexican guttifera 

 is so different in its scheme of sculpture that its confusion with 

 oregona is unaccountable. 



15 The species of the hirticollis group resemble the preceding 

 closely and should perhaps be considered more properly as an 

 extension of it, but the humeral lunule assumes a very different 

 form, which serves constantly to differentiate the two groups. 

 The species are three in number as before enumerated: 



Cicindela gravida ssp. abrupta nov. Form nearly as in gravida but 

 a little narrower, darker and more blackish-brown in color, the markings 

 similar, except that the humeral lunule is broadly interrupted, the pos- 

 terior detached part with an anterior projection which is more pronounced 

 than in gravida, the middle band also sometimes detached from the white 

 marginal streak; pubescence of the front coarser, whiter and less abundant. 

 Length (o* 9 ) 11.5-13.0 mm.; width 4.7-5.35 mm. California (Sacra- 

 mento). 



Differs from gravida principally in the much more acute elytral 

 apices, especially in the female, the sides posteriorly being more 

 oblique behind the dilation near basal third, which is even stronger 

 and more abrupt than in gravida. 



19 The dor sails group occurs exclusively on or immediately 

 behind sea-beaches from New England far into the tropics and 

 consists of numerous species, which are strikingly similar among 

 themselves. The following new forms seem worthy of description: 



Cicindela munifica n. sp. Form, sculpture and ornamentation as in 

 dorsalis but much larger, the head and prothorax notably larger, the 

 latter more transverse and with the sides at base more swollen; labrum 

 larger, relatively less abbreviated; vertex rather more deeply concave; 

 elytra (9 ) more strongly angulate and deplanate at the sides near basal 

 third; under surface similar, except that the last ventral ( 9 ) is more 

 broadly truncate; legs a little less slender. Length (9 ) 15.0-16.0 mm.; 

 width 6.4-6.6 mm. Rhode Island.
