148 WILLIAM G. DIETZ, M.D. 



rax a little wider tliau long, slightly narrowed anteriorly, broadly constricted at 

 the apex, rather broadly rounded on tbe sides and somewhat convergent toward 

 the base; surface densely, coarsely and deeply punctured, a discal, inipunctate 

 line. Scutel moderate, scaly. Elytra two-fiftlis wider at tbe base than the pro- 

 thorax, sides straight and parallel for one-half their length, humeri prominent. 

 distiTictly striato-pnnctate, punctures somewhat remote, third interspace a little 

 widened toward the base, interstitial setse suberect, quite distinct, scales less 

 dense along the sutural interspaces, sides rather conspicously mottled with white 

 scales, humeri and a short basal line on the third interspace white. Prosternum 

 moderately long in front of coxse, broadly emarginate, postocular lobes moderate- 

 Thighs not strongly clavate, tibife rather robust, feebly emarginate within, apical 

 hooks rather distinct; tarsi moderate, third joint less broadly bilobed, fourth 

 projecting the length of the preceding joint; claws connate one-half their 

 length. Length 2.5 mm.; 0.10 inch. Plate vii, fig. 19. 



Hob. — Arizona. 



A unique male specimen in Mr. Ulke's collection. Very distinct, 

 closely allied, structurally, to indabilis, but differing, aside from 

 coloration, in the very robust, strongly curved beak. 



S. quadrifei* n. sp, — Oblong-oval, pitchy black, legs reddish, densely 

 clothed with small, oval scales, yellowish white on the underside, brown varie- 

 gated with white on the sides and apical half of the elytra, dull black on a large, 

 sharply defined, quadrate space extending from near the base to about or slightly 

 beyond the middle. Beak moderate, distinctly though not strongly curved, of 

 nearly equal thickness throughout, scarcely as long as head and prothorax in the 

 male, distinctly longer in the female, rather densely punctured except toward 

 the apex, scaly, substriate each side, basal tufts prominent, incision deep ; scrobes 

 rapidly descending. Antennae moderately stout, inserted one-third ( 'J, ) or two- 

 fifths ( 9 ) from the apex, second joint of fuuicle scarcely longer than the third, 

 outer joints not much wider. Head thinly squamous. Prothorax a little wider 

 than long, feebly narrowed in front, broadly rounded on the sides and not dis- 

 tinctly constricted at the apex; surface not very densely punctured, punctures 

 moderate, interspaces somewhat shining, an indistinct, smooth median line, more 

 distinct before the middle, sculpture not entirely concealed by the scales, a me- 

 dian line and lateral margin whitish. Scutel distinct, glabrous. Elytra scarcely 

 two-fifths wider at the base than the prothorax and more than one-half longer 

 than wide, humeri prominent, sides straight for one-half their length, then 

 l)roadly rounded to the apex; strife fine though distinct, interstitial setae not 

 evident; humeral line and a basal line on the third interspace reaching the 

 large, black space, whitish. Pi'osternum moderately long in front of the coxse, 

 antecoxal ridges not very sharply defined, postocular lobes feeble. Legs not 

 very slender, thighs feebly clavate ; tibiae, subparallel, apical hooks distinct: tarsi 

 rather slender, fourth joint projecting the length of the preceding, claws con- 

 nate beyond the middle. Length 2.2 — 2.5 mm. : 0.09—0.10 inch. Plate vii, fig. 16. 

 Hab. — Arizona (Casey), Alabama (Mobile, Jiilich). 

 Three specimens in Mr. Jiilich's collection are before me. The 

 large quadrate black space of the elytra gives this species a very 

 characteristic ajjpearance. Resembles instabills, for the differentia- 

 tion from which the student is referred to that species.
