terior margin has 2 slight sinuosities, the posterior angles are round- 

 ed off or obliquely truncated. Scutellum obsolete. Elytra fur- 

 nished with a very short elevated ridge at the shoulder. Legs elon- 

 gated ; coxae large, the 2 posterior ones rather distant from each 

 other ; 2 posterior trochanters much elongated, incrassated at the 

 tip ; apex of tibiae subcylindric, but not narrowed, and hairy, es- 

 pecially in the 2nd pair ; joints 2-3 of the tarsi of equal size, the 

 first longer,the 4th a little shorter,the two anterior tarsi slightly con- 

 tracted, 2nd and 3rd pair more and more elongated. Penultimate 

 segment of abdomen with a strong longitudinal groove on the back.

S. statura et magnitudine praecedentis ; testaceus. Antennae art. 

 3-4 subaequalibus, 5 praecedente longiore, 6-8 gradatim minoribus, 

 subglobosis, 7-8 apice fortius oblique truncatis, 9-11 gradatim ma- 

 joribus, subglobosis, clavam formantibus. Palpi maxill. art. ulti- 

 mo minimo semigloboso. Thorax magnus obovatus, basi rotunda- 

 tus, 4 foveolatus. Elytra apice truncata, 2-sinuata. Pedes femori-

Of the general appearance of the former but of a light yellowish 

 color and well distinguished by the large thorax, truncated elytra 

 and abnormal construction of the 2 posterior femora. Antennae 

 with joints 7-8 rather strongly obliquely truncated at the apex, 9-11 

 forming a club, subglobose, flat at the base, the last acuminated and 

 slightly cut away or even excavated on the inside at the apex. Last 

 joint of maxill. palpi semiglobose, these otherwise the same as in 

 the former. Thorax and elytra of S. alatus, the former however, 

 larger, rounded at the posterior margin and with 4 basal impressions 

 the latter slightly truncated at the apex and with a slight sinuosity 

 in the truncature on either side of the suture. Scutellum very small. 

 Legs with the tibiae slightly bent at the base, the apex as in the 

 former: tarsi with joints 1-4 gradually decreasing in size, first pair 

 contracted and furnished with brushes on the inside. The 2 pos- 

 terior legs inserted rather distant from each other, the basal part 

 of abnormal construction : the trochanters are much elongated and 

 incrassated at the tip whilst the femora are at the place of the junc- 

 ture rather abruptly narrowed, bent and slightly compressed, they
