 phimbeo-cinereoiis pubescence. Length 1.5 mm.; Avidth 0.55 mm. 



Utah (southwestern). Mr. Weidt. 



The type and only specimen known to me is a female, the fifth 

 ventral being rather long, strongl}" rounded behind, with the disk 

 feebly impressed in the middle near the tip. The epipleur?e are 

 very narrow, subvertical, and become wholly obsolete long before 

 the apex, as usual in this and allied genera. 



2. I>. praeteniiis u. sp. — Narrow, rather convex, strongly shining, black 

 with a scarcely visible bluish lustre; legs pale; antennae pale testaceous, 

 lilackish toward apex; pubescence rather tine, sparse, decumbent, cinereous, 

 distinct but not conspicuous and without trace of erect hairs or bristling fimbriae. 

 Sead fully four-fifths as wide as the prothorax, flat, feebly reticulate, the 

 punctures not distinct; frontal impressions small, feeble and widely separated; 

 •epistoma rather long, pale; la brum pale, long, strongly rounded ; eyes mod- 

 erately large, convex and prominent; antennsc much longer than the protho- 

 rax, slender, distinctly incrassate toward tip, the penultimate joints strongly 

 transverse and rather compactly joined. Prolliorax two-fifths wider than long, 

 the sides just visibly convergent, evenly and moderately arcuate from base to 

 apex, the angles all obtuse and somewhat rounded though evident ; apex feebly 

 arcuato-truncate, very slightly narrower than the base which is only a little 

 more arcuate; disk obsoletely reticulate, finely and s^jarsely punctate, rugose 

 at the sides, the sublateral impressed line distinct. Elytra two-thirds longer 

 than wide, two-fifths wider than the prothorax, parallel, the sides feebly arcu- 

 ate except toward base; apex evenly rounded; disk fineh' but very distinctly 

 punctate, the punctures rather close-set and feebly asperulate, the interspaces 

 smooth and polished. Under surface very sparsely and inconsijicuously pu- 

 bescent. Length 1.5 mm.; width 0.5 mm. 



Arizona. Mr. Wickham. 



M}' single representative of this species is a female, the fifth 

 ventral being evenly but broadly rounded behind and apparently 

 very slightl}^ impressed on the disk at apex ; the genital segment 

 is smooth, broadly and evenly arcuate at apex, with the disk, 

 transversely impressed and not in the least canaliculate along the 

 middle. The ungual appendages are well developed and fully as 

 long as the claws, to which they are attached nearly throughout. 

 This and the preceding are the smallest dasytide forms known 

 to me. 



3. D. exilis n. sp. — Narrow, rather convex, polished, black; femora 

 black, the tibiteand tarsi piceo-rufous ; antennae piceo-rufous, black toward tip; 

 pubescence fine, rather short, sparse, closely decumbent, even, dark cinereous, 

 not at all consjjicuous but distinct, the marginal cilia not evident; erect setae
