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 ijiore elongated. Penultimate

31. Scydmcenus femoralis. N. 
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 iruncata, 2-sinuata. Pedes femori' 
bus 2 posticis medio constrictis, tarsis art. 1-4 gradatim minoribus. 
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
