230 THE CANADIAN ENTOMOLOGIST 



old Harris label, and found it much darker than the type at Cambridge. It is 

 an almost black insect with the faintest traces of green. It is marked like the 

 type, and is almost exactly as the figure on Plate XIII of the work of 1848. 

 Does it not seem probable that Dr. LeConte made the description from his 

 green specimen, and in some way the figure was made from the black specimen 

 of the Harris collection? This supposition will at least account for the dual 

 colour role of spreta. 



In correspondence with Dr. LeConte, T. W. Harris expressed the opinion 

 that spreta was much nearer limhalis Klug. than purpurea, and that Dr. Le- 

 Conte was in accord with him is shown by the Revision of 1856. 



In 1900, Mr. E. D. Harris took a large series {about 100 specimens) of 

 limbalis at Mt. Desert, Me., and, discovering several dark green ones among 

 them, took one to Cambridge and placed it beside the type, and then to the 

 Harris collection where he made a comparison with the "companion specimen." 

 His conclusion was, "It is, to all intents, exactly the same thing. It is limhalis.'' 



On June 24, 1909, I took a specimen of spreta at Monmouth, Me., in a 

 sparsely wooded pasture on the west shore of Lake Cobbosseecontee. It has 

 been placed beside the type and found to be the same in every respect. An- 

 other specimen from Wales, Me., June 15, 1909, is very much like Mt. Desert 

 limbalis, with reddish-cupreous shading and silky lustre. A specimen from 

 Monmouth, June 25, 1905, is nearly intermediate between the other two, being 

 a more clear green at the base of elytra and becoming gradually cupreous towards 

 the apex, but without definite silky lustre. 



From the above we have sufficient proof that spreta Lee, a rather dark 

 green insect (of about the shade of the green forms of purpurea) with limhalis 

 markings, (humeral, post-humeral and ante-apical dots, sinuate median fasciae, 

 and apical lunules) is but a colour variation of limhalis Klug. as represented by 

 the Mt. Desert specimens. Therefore, Dr. Walther Horn is in error in the 

 Genera Insectorum in placing ''spreta Lee, 1848" as a "senile form" and spreta 

 Lee, 1856, as a "black form" of ptirpurea Oliv. 



Cicindela hentzi Dej., var. niveihamata, n. var. This interesting varia- 

 tion was taken at the Middlesex Fells Reservation in a road near the shore of Spot 

 Pond in the town of Stoneham, Mass., July 26, 1903. It was found somewhat 

 remote from the usual haunts of the species, although they frequently scatter 

 from the ledges to the neighboring roads. The markings of this unique are 

 formed by the extension of the apical lunules along the margin, including the 

 ante-apical marginal spots, to and joining with the obliquely transverse median 

 fasciae; the result is a broad marginal band with sinuate inner edge terminating 

 in a hook at the middle of each elytron. The median ante-apical dot has almost 

 vanished and the humeral lunule is represented by a small humeral dot and a 

 very faint sub-humeral one. The markings resemble those of the posterior 

 half of the elytra of C. schauppi with the transverse fasciae more oblique. In 

 order to stimulate ambition and anticipation among those collectors who delight 

 in aberrant forms this handsome little insect is duly christened as above. 



Pterostichus corusculus Lee. This species, which has hitherto been 

 taken rarely along a railroad embankment through a swamp, was found in 

 large numbers (over 100) under stones, logs and in debris along the shores of
