One specimen (fig. 6), taken at Riverton (Sept. 8) shows 

 an unusual variation, which Baron Osten Sack en refers to as 

 follows : "In the majority of specimens the first submarginal 

 cell is shorter than the second ; in other words, it is the second 

 longitudinal vein which is forked. Sometimes (in two speci- 

 mens among eighteen) the reverse is the case ; it is the third 

 vein which is forked, and hence the first submarginal cell is 

 longer than the second." Fig. 6 shows the left wing ; on the 

 right wing the first and second submarginal cells are of equal 

 length, the veins forming those cells all diverging from one 

 point. Osten Sacken also states that occasionally adventitious 

 cross-veins occur in the second posterior cell. I have not 

 observed this variation. Of the twenty-two specimens before 

 me, only ten have normal venation. 



A New Cicindela, with Notes on Allied Species. 



BY H. C. FALL. 



Among a lot of good things lately received from my friend, 

 Dr. Edwin C. Van Dyke, were eight examples of a Cicindela 

 taken by him the past summer in Humboldt County, Califor- 

 nia, and concerning which he expressed the belief that I would 

 find it, upon examination, to be either a new variety or a new 

 species. It proves indeed to be a good species, somewhat 

 nearly allied to i2-guttata and oregona, and as specimens are 

 being distributed by Dr. Van Dyke, it is desirable that it 

 should have a name. 



C. eureka sp. nov. 



Size of oregona; fuscous, the elytra feebly, the head and prothorax 

 more evidently bronzed, and in part with green and coppery reflections ; 

 beneath blue green. Elytral markings of the oregona type, the humeral 

 lunule interrupted, the middle band not extending along the margin, nar- 

 row, obliquely bent and of nearly uniform width throughout, being but 

 slightly dilated at its inner extremity. Labrum pale, middle tooth mod- 

 erately prominent, lateral ones indistinct or wanting. Front not pilose, 

 vertex with a little group of three to five setae, and two (rarely three) 

 others near the inner angle of the eye ; the emargination of the eye with 

 a single setigerous puncture. Thorax with sides nearly parallel in both 

 sexes. Elytra relatively longer and less dilated than in oregona, espe- 

 cially in the female. In the male, the labial palpi are pale at base, and
