to the Cicindelidcs fditna of Mexico. 505 



of the rufiventris group. The elytra are punctured, as 

 in C. salhei and allies, but the umbilicated foveoles are 

 longer and more numerous towards the base ; the con- 

 jointly rounded apices have nearly smooth edges. 



Cicindela rectUatcra, Chaud. 



This Texan species occurs in the States of Tamauli[)as 

 and Coahuila, under the same form as in Texas ; but at 

 Villa Lerdo in Durango, where it has been collected in 

 large numbers by Mr.Iioge, it presents itself as a tolerably 

 well-marked variety, being generally smaller, the etytra 

 relatively a little shorter, and the white spots larger, the 

 two median spots being sometimes more approximated 

 than usual with traces of a fine line connecting them 

 together. 



Ciei)idela fiavopunctata , Chevr. 



The southern form of this common Cicindela is on the 

 average smaller, and has a decidedly narrower thorax ; 

 the hind trochanters also are always red like the abdo- 

 men, the latter having little or no trace of fuscous at the 

 base. It is a more important variety than any of the 

 others described under this species, and I propose to call 

 it after the name of the State which appears to form its 

 head-quarters. 



Var. C. Chiapana. Thorace angusto eylindi'ico, elytris utrinque 

 niaculis quinque albis, abdomine trochanteribiisque posticis rufis. 

 Long. 10 mm. (J $ . 



Tapachula in Chiapas ; La Noria in Sinaloa {Hix/c) ; 

 Guatemala {Champion) , near the city {Salvin). 



Specimens nearly approaching this in the small size 

 and narrow thorax occur in Central Mexico, but they 

 have the same blackish brown trochanters and base of 

 abdomen as the ordinary typical and rather larger form 

 with quadrate thorax. In Nicaragua and Costa Rica 

 another allied but less slender var. occurs. 



Cicindela sinaloa. 



Sat augusta, elytris elongato-subovatis. Cupreo-fusca snb opaca, 



ociilis mediocriter prominentibus, thorace quadrate, elytris lunula
