 determined as cophysa. 



74. Tramea onusta. 



Texas: Brownsville, Nov. 25, 1910 (C. A. Hart), i teneral $ ; 

 Black Bayou, May 17, 18, 19 and 21, 21 $ , 4 $ ; Bay City, May 24, 2 9. 



Of 23 specimens examined for mites, 9 were infected. 



In I male the basal color on the hind wings reaches only mid-way 

 between the first and second antenodals, the supertriangle is scarcely 

 colored, and the enclosed pale basal area reaches A3, at which point 

 the colored area is only i cell wide. In 10 males the basal color 

 reaches the second antenodal; in 9 males it reaches the third. In 11 

 males the color extends to the distal angle of the triangle; in 8 it 

 extends i cell beyond. In i male the median space and the area be- 

 yond the upper limb of the arculus are colored; in all other males 

 these areas are hyaline. 



In the females the basal color reaches the second antenodal in 5 

 individuals ; the third in 2 others. Color extends to the distal angle 

 of the triangle in 5 females; a short distance beyond in i. The median 

 space and the area beyond the upper limb of the arculus are colored 

 in only I female, hyaline in the others. 



75. Tramea lacerata. 



Texas: Brownsville, Nov. 25, 1910 (C. A. Hart), 2 $ ; Black Bayou,

[Xotes on a Gomphine Exuv'm from Williams Lake, Mata- 

 gorda Co., Texas. 



The exuvia was collected on vegetation in the water May 26, 

 1907, by E. B. \\'illiamson. No adults collected the same day 

 throw any light on its identification. It comes close to the 

 two exuviae described by Hagen (Trans. Amer. Ent. Soc. XII, 

 p. 277, 1885) as "Aphylla prodncta (supposition)." The 

 Academy of Natural Sciences of Philadelphia has a dried 

 larva from Kissimee River, Florida, which agrees with this 

 description. From the description quoted and the Kissimee 

 River larva, the Texas exuvia differs as follows : 



Smaller size, 43 mm. long; 6 mm. broad (in front of bases of wing 

 pads). 



"Palpus" of the "mask" with three teeth instead of four before the 

 end hook; teeth shorter, less equally stout, the first and second proxi- 

 mad to the end hook being more slender than the third proximad to 

 the end hook (i. e., the most proximal tooth of all.) 



Abdomen shorter (30.5 mm.), loth segment shorter (11 mm.). (The 

 Kissimee larva has the loth 20 mm. long.)
