484 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.52. 



Among these were a male and female Agrion aequahile (Say), the 

 first recorded from California, which were larger than var. yakima 

 and had slightly more color in the wings. These are apparently an 

 undescribed race. This is the third variety of aequahile fomid in the 

 West, var. yakima being found in the Columbia River basin, var. 

 coloradicum * described from Boulder County, Colorado, and this 

 form now foimd in California.^ 



Mr. and Mrs. Reynolds have very kindly deposited these specimens 

 in the United States National Museum. 



AGRION AEQUABILE CALIFORNICUM, new variety. 



Tifpe.—Csit. No. 20814, U.S.N.M. A male from the collection of 

 L. R. and C. D. Reynolds, taken at Blue Lake, Humboldt County, 

 California, May 6, 1911, by F. W. Nunenmacher. 



Allotype.— Cat. No. 20814, U.S.N.M. A female from the collection 

 of L. R. and C. D. Reynolds, taken at Blue Lake, Humboldt County, 

 California, May 6, 1911, by F. W. Nunenmacher. 



Male, color. — Thorax and abdomen metallic blue, except the second 

 lateral suture, the metepisternal keel and the dorsal edge of the me- 

 tinfraepisternum, which are creamy. Coxae and legs black. Pteros- 

 tigmas absent. Wings (fig. 1) flavescent with the apices dark. 

 The specimen is teneral so that the wings are not as dark as in the 

 figure. The front wings are dark on the apical three-fourths of the 

 distance from nodus to apex. The hind wings are dark on the apical 

 four-fifths of the distance along the costa from the nodus to the apex. 

 In the front wings the basal edge of the dark area is vertical to the 

 costa. In the hind wings it slants from the costal edge toward the 

 base of the wing, reaching the anal margin opposite the nodus. 



Female, coZor.^-Similar to that of the male but general body color 

 metallic green. Labrum creamy with a black center. Abdominal 

 segments 8-10 with a middorsal pale stripe and their sides largely 

 pale. Wings (fig. 2) with white stigmas. Front wings with the dark 

 area covering the apical three-fifths of the distance from nodus to 

 apex. In the hind wings the dark covers, along the costa, the apical 

 three-fourths of this distance. The basal edge of the color is perpen- 

 dicular to the costa in the front wings and diagonal in the hind wings. 



Male, abdomen (including appendages), 40 mm.; appendages, 15; 

 hind wing, 32. Female, abdomen, 39; hind wing, 35. 



2. NOTES ON LESTES STULTUS AND ITS NYMPH. 



This black Lestes was described in 1861 by Hagen'' from a single 

 mutilated male in the Museum of Comparative Zoology. Since that

2 Since writing this I have found in the Cornell collection a male Agrion aequahile yakima taken at Cor- 

 vallis, Oregon, June 29, 1896. This is west of the crest of the Cascade Mountains. In the collection of 

 the U. S. Biological Survey in Washington, D. C, are a male and a female of Agrion aequahile collected 

 on the Owyhee River, Rome, Malheur County, Oregon, June 20, 1915, which are intermediate between 

 variety yakima and variety calif ornicum. Other specimens of californicum from Seattle, Washington, 

 are in the collection of Dr. Philip P. Calvert.
