22 MEMOIRS ON THE COLEOPTERA 



but especially the different structure of the hind legs. The hind 

 tarsi in the type are very long, in fact almost one-half longer than 

 the tibiae, while in the male of graminea they are only a third or 

 fourth longer than the tibiae. 



Cicindela purpurea ssp. inducta nov. Body black throughout but 

 with a feeble greenish tinge especially anteriorly, the under surface 

 bright coppery, the metasternum and sides of the abdomen basally 

 green, the remainder of the abdomen blue, the apices of the segments 

 green; legs obscure coppery-green; elytra with the side margins only 

 differing slightly from the disk and obscure coppery, the markings 

 consisting of a humeral and post-humeral spot, a median band oblique 

 internally and about attaining the outer edge, along which it is slightly 

 expanded anteriorly, and a complete apical lunule which is bent at the 

 middle to form a right angle. Length (cf ) 11.5 mm.; width 5.0 mm. 

 Colorado. 



Much smaller than aiiguralis or auduboni and differing from the 

 latter very greatly in maculation and from both in color throughout. 



Limbalis Klug, is a species different from purpurea. The penulti- 

 mate joint of the labial palpi frequently becomes pale in limbalis, 

 though this may not be entirely constant within the same specific 

 or subspecific form in this group, but I have never noted an instance 

 of its becoming pale in purpurea or in any of its subspecies. The 

 body is much narrower and more elongate than in the typical 

 purpurea section. I think that transversa Leng, of w r hich I have a 

 single example from Indiana, is a member of the limbalis and not 

 of the true purpurea section, and splendida is also a limbalis-\ike 

 species. I do not seem to have either sprela or amcena of LeConte 

 and so cannot judge definitely concerning them, but from what is 

 quoted by Mr. Leng they also would seem to be of the limbalis 

 type. Limbalis is represented in my collection by a good series 

 from Connecticut to Iowa; one male from Fort Gratiot, Mich., is 

 shorter in the hind body than any other, but there seem to be but 

 few other differences; the color above is coppery-red, the side mar- 

 gins metallic-blue, the thoracic sulci also blue; they all have a 

 humeral and post-humeral pale spot, the elbowed middle band 

 penetrating the blue margin and sometimes virtually attaining 

 the elytral edge but never expanding along the latter, a transverse 

 apical streak and a detached subapical external spot; no one of 

 my examples has a complete humeral or apical lunule. The follow- 

 ing is a very beautiful and much smaller development:
