closely covered ^'illi ring punctures, except along tlie centre. Elytra 

 half as long again as together broad at tlie shoulders, sliglitly 

 narrowed heiiind , separately rounded at the apex and strongly 

 sinuate Ixdow the shoulders, flattened on the disk and strongly 

 deflexed at tiie sides, tlie ring punctures, mostly of oval form 

 and arranged in somewhat regular rows on tlie disk, and beco- 

 ming more confused and strigiform towards the sides. Pygidiura 

 transverse sub-elliptical, very convex, with ratiier closely jdaced 

 ring jiunctures, and a feeble longitudinal carina. Metasternum 

 and abdomen witli ring punctures at the sides, and an irregular 

 strigiform punctuation in tlie middle, the former witli an impressed 

 median line; prosternai spine long, obtuse and hirsute; inesosternal 

 process small and rariniform; the four basal segments of the 

 abdomen broadly impi-essed in the centre; the last spiracle placed 

 on a slight prominence in the middle of the sides of the apical 

 dorsal segment. Legs rather short, femora and tibia \'ery densely 

 strigose-punctate, anterior tibiae with a broad rounded apical lobe 

 and three small obtuse teeth, the lower two contiguous, the 

 upper one more remote and situate above the middle ; the six 

 joints of the anterior tarsi as broad as long and sub-e(jual; inter- 

 mediate and posterior tibiae witli an acute sub-median tooth, 

 their tarsi five jointed , the joints longer than broad ; ungues of 

 all the tarsi very small. Length 20 nun., greatest breadth (at the 

 shoulders) 8 ' .j mm. Sesse Archipelago, Victoria Nyanza. 



In adhering to Westwood's classification and tabulation , in 

 his Monograph of the Cremastoclieilides ('), this most remarkable 

 and interesting addition to our knowledge of the group would 

 come next to tlie Soutli American genus CycUdius which it most 

 nearly resemble in its elongate and parallel liuild, form of pro- 

 thorax, cariniform mesosternal process, minute tarsal ungues, and 

 opake velvety surface. In the possession of six-jointed anterior 

 tarsi it differs, as far as I am aware, from all other known 

 Coleoptera, but, as at present only a single specimen is known, 

 it is of course possible that in this respect it may be an abnormal 

 individual, although from ail appearances it has the aspect of 

 i)eing a jierfectly normal and natural examjde. If, upon the 

 discovery of further examples , the six-jointed tarsi should prove
