Cvlevj'tera from the Seychelles hlandsy ^c. 129 



Tlic present ffoinis diflTors from most of the otiicr genera 

 l)cl()Uf:iiij4 to the Disteniini hy liaviii<j; the jtrotlioriix short, 

 re^uhirly convex, and unarmed. From the ^cnus Euyale- 

 lius, Kairm., whieh also lias an unarmed prothorax, it seems 

 Itt difVer by the much sliorter prothorax, the longer antennic, 

 and tiie shorter Ixisul joint of the hind tarsi. 



The majority of specimens of the Hrst two species of this 

 genus were hrcd front larv;e found in fallen and rotting 

 sticks of endemic trees, principally Xorthea, in the highest 

 forests. The records given below show that the gicater 

 number of tliese larvae were collected in Silhouette in the 

 drii'r months of August and September, but some were also 

 obiaincil in Mahe iu December. 



5. Micruncemia albosi(//ia(a, sp. n. (PI. XII. fig. 1.) 



Body black, with some markings of greyish-white |)ubes- 

 eence ; tlie face before the anteniifc, the femora, and joints 

 3-7 of the antenn.'o, except at apex, brown or brownish; 

 the fiist and the four last joints of the antenme as well as 

 the tibiio and tarsi more or less daikened, fuscous. Sides 

 of the meso- and nietasternum, liind margin of pronotum 

 (rather broadly), two transverse bands on the elytra (one 

 b fore and one behind the middle), the suture between the 

 bands, an oblique stripe between the bands emitted from 

 the suture, and the apical tiftli of the elytra, densely clothed 

 with white or greyish pubescence. Length 7-9 mm. 



I'roiiotnm transverse with the sides strongly rounded. 

 The dytral rows of punctnies are somewhat irregular at the 

 base and cease at the posterior white band or a little behind 

 it ; the snbhumeral and humeral rows are very distinct and 

 regular, the latter forming a distinct edge. The white 

 markings of the elytra are sometimes indistinct or almost 

 wanting (by al)rasion?).

" Of the 1 1 examples H were br( d from larvic or pnpre, 

 six of which were found in the high forests of Silhouette in 

 August or September, and two in the hi;;h forests of Mahe 

 in Deceniber, at varii)us places between 1000 and 2400 feet. 

 One specimen bears a record of having been bred fn)m a 

 fallen stick of tin- endemic ' Capucm ' (Xort/nui) tree from 

 the highest peak of Silhouette, and, as far as 1 can remember, 

 most or all of tiie larvie were found in fallen and rotting 

 sticks or quite snnill brandies of dicotyledonous trees, 

 possil)ly Ni>rthcfi in every ease. Compare the records given 

 under the following sp,, M. ghuca^ and its ab. humirulis.
