extreme apex ; densely covered with narrow scales, near apex glabrous and rather 

 sparsely punctate at sides. Antennae inserted slightly below middle ; 7-jointed, 

 second funicular joint much shorter than the first and only slightly longer than the 

 third. Prothorax slightly longer than wide; sides in basal half feebly arcuate, then 

 gradually narrowing to apex, which is rather feebly constricted. Elytra wider than 

 the prothorax, humeri obliquely rounded ; sides gradually, arcuately narrowing to 

 apex; apex rather broadly rounded. Length 2.5 mm.; width 1 mm. 



Ithaca, New York. One specimen retained from material sent me 

 by Mr. J. C. Bradley for determination. By the small, slender scales 

 this species is related to sordidus, but is much smaller, of more 

 elongate form and has a much shorter second funicular joint. 



Tychius suturalis, new species. 



More broadly oval than lineellus but smaller, scales of upper surface ferruginous, 

 except the sutural interval, an antescutellar spot on thorax and the underside, white. 

 Beak thick at base, rapidly narrowing toward apex ; densely covered with pale scales 

 in about basal half, apical part smooth and shining. Head above the eyes trans- 

 versely impressed. Prothorax about as wide at base as long : sides arcuately nar- 

 rowing from base to apex, the latter rather feebly constricted ; the coarse punctuation 

 entirely concealed by the vestiture which consists of oval, uniform, ferruginous scales, 

 whitish in an antescutellar spot and a small subbasal spot near each side. Elytra 

 slightly wider than the thorax at base ; broadly oval ; densely clothed with elongate- 

 oval, ferruginous scales of uniform size, those of the sutural interval and umbone 

 whitish ; striie with a row of sparsely placed scales, of the same size as those on the 

 intervals. Body beneath densely clothed with slightly larger, white scales, those on 

 the legs pale-yellowish. Length 3.5 mm. 



Huachuca Mts., Arizona. 



The absence of elytral seta? and the 7-jointed antennal club place 

 this species in Casey's group I ; from the other species of which it 

 differs by the short robust form, the ferruginous color of the upper 

 surface with the sutural interval white. The elytral apices are rather 

 separately rounded, but not as broadly as in our two species of Sibinia. 



Tychius pallidus, new species. 



Form of Sibinia ochreosa ; scales of upper surface rather larger and of uniform 

 size, pale ochreous and white ; elytral intervals with a row of short, semi-erect seta. 

 Head and beak moderately densely clothed with whitish scales which are narrower 

 in front of the eyes; apical half of beak glabrous, shining. Antennae inserted about 

 middle ; funicle 6-jointed. Thorax about twice as wide as long ; sides arcuately 

 narrowing to apex, the latter moderately constricted ; surface covered rather densely 

 with moderately large, pale ochreous scales, which become whitish at sides. Elytra 

 scarcely one half wider than the thorax ; humeri obliquely rounded ; sides parallel to 

 about apical third, thence arcuately narrowing to apex ; surface densely clothed with 

 rather large ochreous and white scales, the latter color more evident at the humeri 

 and in a somewhat oblique fascia from the scutellum to about the middle of elytra ;
