THE CANADIAN ENTOMOLOGIST. 65 



segment i, 37-45 /^ long j segment 2, 37-39 /'- long; segment 3, 28-40 /v. 

 long; segment 4, 28-34 /x long; segment 5, 22-31 //. long; segment 6, 

 22-34 /x long ; segment 7, 73-84 /x long; legs, femur about 140 /i. long ; 

 tibia, about 100 /x long ; tarsus, about 70 // long ; derm bearing vieculiar 

 spear-shaped spines. This species does not resemble D. Toivnsendi, 

 Ckll., as supposed by Maskell. It resembles albizzice, Mask., and 

 hymetiodece., Ckll, in producing the blue-green pigment in potasli, but is 

 distinct from them in the secretion and anatomical characters. 

 Dactylopiiis Texensis, n. sp. 



Specimens have been in alcohol since Dec, 1895. Adult $ ; length 

 about 3mm.; nearly as wide as long ; shape rather sub-globular ; colour 

 light brown. I know nothing at present of the secretion. Epidermis 

 bearing scattered, medium-sized hairs and numerous small glands ; 

 margins of body with areas of glands and stout conical spines. Antenn?e 

 of eight segments : segment i rather large, 53-59 /^ long ; segment 2 

 rather wide, tapering slightly toward the pro.Kimal end, length 48-51 /x ; 

 segment 3 about three-fourths the width of 2, cylindrical, 52-62 /x long 

 (the length of this segment may be either less than, equal to or greater 

 than that of i, they are often nearly sub-equal); segment 4 quite short, 

 20-2S /x long; segment 5, 28-37 /•'- l*^"g 5 segment 6, 25-31 //. long; 

 segment 7, 31-39 /x long; segment 8 usually about 84 /x long. Among 

 observed formuhe are : S312 (57) (46), 83127564, 81327 (56) 4. The 

 segments bear one or more whorls of medium-sized hairs. 



Legs rather short and stout ; femur about 182 /x long by 82 /x wide, 

 bearing numerous medium-sized hairs ; tibia, 132 /x long by 35 /x wide, 

 bearing several rows of small hairs ; tarsus 65 /x long ; tarsal digitules 

 long, slender, knobbed hairs; claw stout, 31 /x long ; digitules of claw 

 long, slender, knobbed. Mentum elongate. Anal lobes not conspicuous, 

 bearing the usual long spine, and areas of cones, hairs and spinnerets. 

 Since the specimens are alcoholic, we know nothing of the ovisac. Eggs 

 unknown. Male unknown. 



Hab. — On Acacia Far?tesiafia,\N \\\d.; San Diego, Texas, Dec, 1895. 

 U. S. D. A., Div. Ent , No. 6961. 



Remarks. — This species resembles D. Ryani in antennal formula, but 

 differs in having the antennae smaller and the legs shorter and stouter. 

 Resembles D. dasyiirii in the general form of the antenna-, but differs in 

 having segments 3 and i of antenna? usually longer than 2, and differs 

 very much in the shape of the body.
