362 PROCEEDINGS OF THE ACADEMY OP 



present state of progress of Entomology very undesirable ; the complication in 

 bibliography and the difficulty of reference being sources of greater injury 

 than the advantage resulting from the knowledge of the species thus published. 

 And the motives which induce me, on the present occasion, to violate my well- 

 established opinions of what is best for the interests of science are ; first, the 

 number of genera not previously represented in our territory; and secondly, by 

 numbering the papers in a regular series, to render them really supplements to 

 the " List " and " JS T ew Species " above mentioned. At the same time I shall 

 rigidly exclude from this series any species which can be described in any 

 monographic or faunal memoir which may soon be elaborated. Varieties or 

 races of described species which have not been previously noticed in print will 

 also be mentioned. 



Since the publication of my last descriptions of Coleoptera, the metrical 

 system of weights and measures has been adopted and authorized by the 

 Government of the United States. The measurements used in the present 

 series are millimetres, and can be converted approximately into hundredths of 

 an iaeh, (the measure used in my previous memoirs,) by multiplying by four. 



CICINDELA Linn. 



1. C. obsoleta Say. A remarkable variet}', or rather race, of this species 

 was collected at Fort Whipple, Arizona, by Dr. E. Coues, U. S. A. It is of 

 large size, (19 mm.,) dark blue color, tinged with green, the thorax less flat- 

 tened than in race p r a s i n a , but less convex than in race vulturina, with 

 the pale, markings of the elytra perfect, as in the best developed specimens of 

 the latter: viz., a humeral spot, a submarginal spot before the middle, a medial 

 band not attaining the margin, composed of two spots connected by an oblique 

 line, an apical lunule, consisting of a terminal margin dilated into a spot 

 anteriorly about one-fifth of the length of the elytra; the legs and under sur- 

 face are dark blue, with the last ventral segment black. 



2. C. longilabris Sen/. A variety of this species occurs in Colorado, in 

 which the color above is dark brown slightly bronzed, the humeral lunule 

 entire, connected with the medial band by a narrow submarginal white line, 

 and the apical lunule entire and dilated anteriorly into a large spot. The 

 under surface and legs, as usual, are blue green. For a specimen I am indebted 

 to Dr. S. Lewis. 



3. C. nigroccerulea Lee. Mr. Ulke has a specimen of this species, 

 from Colorado, in which the color above is dull leek-green, and the elytra are 

 immaculate. 



4. C. rufiventris Dej. Chaudoir (Cat. Coll. Cicindelites, 1865,) con- 

 siders C. 16-punctata and C. cumatilis as varieties of this species. 



5. C. dorsal is Say. Chaudoir (loc. cit.) regards C. media Lee. and C. 

 Saulcyi Guerin as varieties of this species. I have in the list already placed 

 the former as a race of C. d o r s al i s, but the much smaller size, and the 

 less development of the tooth on the right mandible of the male, seem to 

 establish the specific nature of C. Saul cyi. 



G. C. repanda Dej.. C. 12 -guttata Dej. is placed by Chaudoir as 



a variety of this species. 



7. C. obliquata Rirby, as I learn from a drawing 

 made by Mr. Andrew .Murray, from the type in the 

 British Museum, is quite distinct from any species known 

 to me. The annexed wood cut will show the character of 

 the markings better than any description. The species 

 should hereafter be known as C. K i r b y i.
