moderately, the others lightly), hind ones extending to about 

 middle of second abdominal segment; basal joint of tarsi 

 conspicuously inflated, concave on lower surface, almost as 

 long as two following joints combined, and much wider than 

 either. Length, 15 mm.

The general outlines are much as on bidentatus, centralis, 

 and hemistictus; the elytral markings are as on some speci- 

 mens of scalaris, but it is wider than that species, and the 

 second-fourth joints of antennae are very differently propor- 

 tioned. In my table it would be associated with sparsus, but 

 is wider, differently clothed, third joint of antennae very 

 different, etc., I do not think it should be referred to D, of 

 that table, as the pale elytral clothing, although confined to 

 the suture, is distinctly spotted. On the under-surface the 

 pubescence is rather dense on the sides, especially of the 

 sterna, but there is a narrow nude space on each side of the 

 metasternum, and a somewhat rounded nude spot on its 

 episternum ; on the abdomen the pubescence is sparse along 

 the middle, and irregular about the sides, with a (not very 

 sharply defined) nude spot on each side of each of the four 

 basal segments. The basal joint of each tarsus is conspicuously 

 inflated, more especially on the front pair. 



Belus variabilis, n. sp. 



Piceous-brown ; some parts black, elytra paler but some- 

 what infuscated about suture, apical half of rostrum and parts 

 of legs reddish. Irregularly clothed with whitish (in some 

 places stramineous) pubescence. 



Head densely granulate-punctate between eyes, with 

 finer sculpture at base. Rostrum rather long, thin, and 

 lightly curved; with rather coarse punctures behind antennae, 

 in front shining and with small punctures. Antennae 

 moderately long, third joint slightly longer than fourth, 

 slightly shorter than first, and conspicuously longer and 

 thinner than second, eleventh about twice as long as first. 

 Prothora.r moderately transverse, sides gently rounded, base 

 not much wider than apex, median line well-defined, densely 

 granulate. Elytra thin, very little wider than prothorax, 

 parallel-sided to near apex, which is lightly produced, suture 

 scarcely elevated at base; densely granulate-punctate. Froat 

 femora lightly dentate or edentate, the others shorter and 

 edentate, hind pair just passing tip of first abdominal seg- 

 ment; basal joint of tarsi as long as the two following 

 combined. Length, 8-9 \ mm.
