moderate; scape very feebly arcuate, not attaining the anterior margin 

 of the prothorax, setose and sparsely scaly; funiole seven-jointed, dis- 

 tinctly longer than the scape, setose, first joint as long as the next two 

 together; club elongate-oval, finely pubescent, scarcely one-half as long 

 as the scape. Tibiae distinctly mucronate throughout. 



The first ventral segment is practically straight, but upon 

 very close observation is seen to be very broadly and excessively 

 feebly arcuate in the middle two-thirds, and exceedingly feebly 

 and anteriorly oblique at the sides. The genus should properly 

 be considered a connecting link between Paraptochus Seidl. and 

 Thricolepis Horn, from both of which it is certainly distinct, 

 according to the present mode of estimating generic differences 

 in the group Periteli. 



S. incotistans n. sp. — Moderately robust, convex, very densely 

 clothed with rather small, minutely and densely striate scales, which 

 are slightly wider than long; scales sparser on the legs and body 

 beneath, entirely replaced by fine hairs towards the apex of the abdo- 

 men; general color above white, with a large, oval, darker discal area 

 on the elytra, which is limited behind by a transverse, very irregular, 

 angular band of white, margined anteriorly with castaneous; bases of 

 the fourth and sixth intervals, and an elongated spot on the sixth inter- 

 val, confluent behind with the white sides, also white; broad median 

 area of the pronotum dark-brown, the stripe being slightly dilated be- 

 hind and slightly paler along the median line. Head feebly convex, 

 with a fine, short median stria between the eyes; the latter rather con- 

 vex, at more than their own length from the prothorax; beak separated 

 from the head by a transverse, feebly arcuate impression, longer than 

 wide, fiattened, apex glabrous and with a small, triangular, impressed 

 area in the middle of the apical margin. Prothorax one-third wider 

 than long, subcylindrical, very slightly narrower toward apex; sides 

 broadly subangulate; base truncate; apex very broadly, feebly arcuate; 

 disk finely, rather unevenly and not densely punctate, each puncture 

 bearing a short, erect, squamiform seta. Elytra oval, in the middle 

 twice as wide as the prothorax, one-half longer than wide; apex per- 

 pendicular, acutely rounded; disk convex, finely, deeply striate; striae 

 finely, not closely punctate; intervals feebly convex; suture fine, dis- 

 tinct. Legs moderately robust. Metasternal episterna narrow, distinct. 

 Length 3.5-5.0 mm.

The typical representative is the darkest in color, and the other 

 two are so pale that the dark areas spoken of in the description 

 can scarcely be discerned. Each elytral interval bears a single
