to the Cicindeliche fauna of Mexico. 509 



There is a large series of this elegant species from 

 each of the two localities named above. Those from 

 Acapulco show nearly all a larger extension of white 

 colour on the elytra than those from Manzanillo. 



Cicindela dehilis. (PI. XVI., fig. 12). 



C. celerijJes (Leconte) affinis. Parva angusta, thorace fere 

 cylindrico angusto ; fusco-uigra (capite plus minusve cuprascenti) 

 raro viridis, subtixs nigra vel cyanea metallica, supra opaca ; elytris 

 vitta subniarginali (apud humeros et versus apicem marginem 

 attingenti) intus bidentata guttaque discoidali interdum per fasciani 

 tenueni obliquam cum vitta marginali conjuncta, albip, margine 

 ipso plus minusve polito, cupreo. Long. 8 — 9 mm. 



Hab. Ciudad in Durango (Hoge). 



The upper surface is opaque, so that the sculpture of 

 the thorax and elytra is scarcely visible. The labrum 

 is white, produced in the middle and unidentate, the 

 anterior margin being sinuated and the angles sub- 

 rectangular. The eyes are rather large and prominent, 

 the vertex depressed, and with the forehead densely and 

 finely strigose. The thorax is narrow and nearly cylin- 

 drical, a little narrowed near the base; the sides are 

 clothed with white laid hairs. The elytra are rather 

 narrow, though together about twice as broad as the 

 thorax, oblong in the 3" and elongate-subovate in the ? ; 

 the apical margins in the S are rather sharply rounded 

 and sinuated close to the sutural apex, which is spined 

 and considerably retracted in the ? . The under surface, 

 especially on the metasternum, is sparsely and loosely 

 pubescent. The trochanters, apex of femora, and the 

 whole of the tibiae and tarsi, are fulvo-testaceous 



C. celeripes, Lee, in Chaudoir's catalogue, is the type 

 of a group (to which C. dehilis belongs) placed next to 

 the C. germanica group.
