anterior tarsi slightly contracted, second and third pair more 

 and more elongated. Penultimate segment of abdomen with 

 a strong longitudinal groove on the back. 



31. Scydmcenus femoralis, N. 



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

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

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

 majoribus, subglobosis, clavam formantibus. Palpi maxill. art. 

 ultimo minimo, semigloboso. Thorax magnus, obovatus, basi ro- 

 tundatus, 4-foveolatus. Elytra apice truncata, 2-sinuata. Pedes 

 femoribus 2 posticis medio constrictis, tarsis art. 1-4 gradatim 

 minoribus. 



Of the general appearance of the former, but of a light yel- 

 lowish colour, and well distinguished by the large thorax, trun- 

 cated elytra, and abnormal construction of the two posterior 

 femora. Antennse with joints 7-8 rather strongly obliquely 

 truncated at the apex, 9-1 1 forming a club, subglobose, flat at 

 the base, the last acuminated and slightly cut away, or even ex- 

 cavated on the inside at the apex. Last joint of maxillary 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 four 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 

 two posterior 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 juncture rather abruptly narrowed, bent and slightly 

 compressed ; as they are at the same time thinner than the ad- 

 joining apex of the trochanter, the constriction is very striking. 



32. Scydmaenus Ceylanicus, N. 



(S?. alati colore, sed major et magis depressus. Long. corp. | lin. 

 Caput magnum, robustum, thoracis latitudine. Antennse basi non 

 approximatse, art. 3-4 et 5-7 inter se subsequalibus, arcum for- 

 mantihuSi 8-10 gradatim majoribus, subglobosis, depressis, apice 

 oblique truncatis, 11° magno, conico, 8-1 1 longius pilosis, clavam 

 formantibus. Palpi maxill. art. 4° minimo, semigloboso. Thorax 

 ovatus, foveis basalibus nullis. Elytra apice singulatim rotundata. 

 Pedes validi tarsis art. 1-4 suba^qualibus, 2 anterioribus art. 1° 

 subtus acumine sat forti producto. 



An anomalous species, especially with regard to the antennae.
