AKT. 9 DIGGER WASPS OF GENUS PODALONIA — FEENALD 27 



punctured and with stout hairs; frons more finely punctured and 

 with finer hairs; one markedly larger puncture behind each lateral 

 ocellus nearly in line with this and the median ocellus; inner margins 

 of compound eyes slightly nearer above than below (always?) ; anten- 

 nal scape, pedicel and first segment of filament shining, remainder 

 dull; mandibles shining black but with a ferruginous tinge near the 

 middle, varying in strength in dift'erent specimens. 



Thorax: Prothorax rather sparsely punctured, its sides in front of 

 the prothoracic lobe strongly rugose; the top of the collar in front of 

 the mesonotum rounded laterally but tending toward a higher median 

 portion with a slight depression on each side rather than an even 

 curve; mesonotum sparsely punctured, with distinct median anterior 

 groove; scutellum smooth in front except for a few punctures; shghtly 

 rugose behind; postscutellum with a central, oblong-oval area raised 

 above the rest of the plate which is confused in markings, and dull; 

 propodeal disk dull, its surface covered by irregularly transverse 

 ridges, often connected, and with punctures between, and bearing 

 long hairs; end and sides similar except that at the sides of the petiole 

 the ridges are vertical, parallel, and more distinct; near the propodeo- 

 metapleural suture the ridges are not evident; metapleuron dull, 

 covered by somewhat irregular but approximately vertical ridges 

 (sides of propodeum, the meso- and metapleura vary in amount of 

 rugosity in different specimens) ; mesopleuron irregularly, coarsely 

 punctured, more or less rugose. 



Abdomen: Petiole short, stout, straight, only slightly longer than 

 hind coxa, its enlarged end under the first dorsal plate, black; first 

 dorsal plate rising quite sharply from the petiole, but less so than in 

 Ivctuosa; this plate and the rest of the abdomen a rich, deep, rather 

 shining blue — almost navy blue — with scattered, minute punctures 

 most abundant toward the hinder margin of each plate; last plate 

 more uniformly punctured and bearing larger hairs. 



Wings: Quite strongly fuliginous with a violet reflection, the hind 

 pair the least, but strongly so beyond the veins; veins piceous to 

 black; tegulae black, sometimes shghtly piceous. 



Legs: Black, sometimes tinged with piceous to brown; spines of 

 the color of the leg segments to which they are attached ; fore-tarsal 

 comb-spines long, of nearly equal diameter from base to tip, the other 

 spines more slender and pointed; claws pale brown; pulvilli moder- 

 ately developed. 



Male. — Body more slender than in the female. Clypeus and frons, 

 to insertion of antennae in the middle and well up toward top of the 

 eyes at the sides, densely silvery pubescent, the hairs forming this 

 being unusually fine and closely decumbent; anterior margin a con- 

 siderable distance below the eyes, its outer third rounded, its middle 

 transverse, very slightly emarginated.
