their length, rather finely striato-pmictate, punctures remote, interspaces flat, 

 fourth, fifth and sixth uarrowed toward the base, setae erect, yellowish, evident, 

 the pale scales forming a line on the base of the third interspace and irregular, 

 transverse bands on the disc. Legs long and slender, femora feebly clavate, 

 tibiae parallel, slightly widened at the apex, terminal hook of anterior and mid- 

 dle pair quite distinct, posterior extremely small ; claws very small, connate one- 

 third their length. Length 3.5 mm. ; 0.14 iucli. 



Hah. — Iowa. 



A single male specimen in Mr. Ulke's collection is before me. 

 Remarkable for the very small claws and terminal hook of posterior 

 tibise. It resembles nebulosus and maculaius, to which the student 

 is referred for reference. Since the above was written I have dis- 

 covered another specimen among Dr. Horn's material ; it agrees 

 with the above, but has the prothorax a trifle more rounded and the 

 posterior tibial hook a little more distinct, labeled Kansas. 



S. iiliictllatuf^ n. sp.— Oval, robust, rufo-piceous, legs reddish, ratherdensely 

 clothed with oval scales, grayish white on the underside, above pale brown and 

 smaller, mottled with oblique or subtransverse, irregular bauds of larger yellow 

 or grayish yellow scales. Beak long and slender, cylindrical curved, basal tufts 

 conspicuous, incision not deep; male: a little longer than head and prothorax, 

 subopaque, punctured in its basal half, which is thinly clothed with hair-like 

 scales, apical half feebly punctate; female: slender, considerably longer than 

 head and prothorax, less punctured and more shining than in the male; scrobes 

 subparallel. Antennae inserted two-fifths from the apex ( % ), or at the middle 

 { 9 )i slender ; first and second joirits of funicle elongate, latter nearly twice as 

 long as the third, outer joints scarcely wider. Head almost without lustre, 

 punctured, front scaly. Prothorax fully one half wider than long, moderately 

 narrowed anteriorly, strongly rounded on the sides, apex distinctly but not 

 broadly constricted, densely and coarsely punctured, punctures almost entirely 

 concealed by the scales, ei-ect setae not very conspicuous, a narrow median line 

 and two spots on each side of the disc of pale scales. Scutel small, distinct. 

 Elytra less than one-third wider at the base than the prothoi-ax, sides nearly 

 straight for one-half their length, finely striato-punctate, interstitial setae rather 

 short, not at all conspicuous. Thighs clavate, tibiae slender, nearly parallel, 

 hooks distinct, claws connate one-third their length. Length 3 — 3.5 mm.; 

 0.12—0.14 inch. Plate viii, fig. 20a. 



Hab. — Pennsylvania, Allegheny Co. (Hamilton), Dakota (Ulke). 



Closely resembles perfidus, from which it differs by its more trans- 

 verse and differently sculptui-ed prothorax, the larger claws and dis- 

 tinct posterior tibial liook. Capt. Casey determined this species as 

 flavieans Lee, which is an altogether different insect, from nebulmus, 

 to which also it bears considerable resemblance ; it differs by its 

 more robust form and more bright yellowish scales. 



S. eoliillibismiiis n. sp. — Elongate-oval, piceous, legs reddish, densely 

 clothed with elongate, brown scales, palei- on the underside, coiLsjiicuously va-
