298 Longicornia Malayana. 



varying according to the light; head and prothorax with very few 

 punctures, the anterior transverse groove of the latter obsolete in 

 the middle; scutellum semicircular ; elytra with greyish patches in 

 consequence of a more condensed pubescence, but varying with 

 the light, apices obliquely truncate, the outer angle obtuse ; body 

 beneath brown, legs and antenuEe testaceous, all with a fine 

 greyish pubescence, scape gradually thickened as far as the 

 middle, cylindrical beyond. 

 Length 6 lines.

Monochanms captiosus. 



M. fuscescens, pube sericea brevi tectus ; elytris griseo-mutan- 

 tibus, apicibus truncatis, angulo exteriore in spinam longam 

 producto ; antennis annulatis. 



Sab. — Dorey, Menado, Kaioa. 



Brownish, covered with a short silky pubescence ; head and 

 protliorax with few punctures, the latter with a slightly raised 

 central line; scutellum semicircular; elytra with small patches, 

 greyish or brownish according to the light, and having a slightly 

 oblique direction downwards towards the suture, the apices 

 truncate, the outer angle produced into a spine, the length of 

 which is nearly equal to the breadth of the truncature; body 

 beneath and legs reddish-testaceous with a greyish pile; antennas 

 three times as long as the body, testaceous, pubescent, tips and 

 bases of the joints dark brown ; scape moderately thickened 

 upwards. 



Length 8 lines. 



A minute analysis of the three specimens I have here brought 

 together as one species would necessitate a separate description of 

 each ; and this remark might be applied to other species of this 

 very variable genus. 



31oiioc/iomus anxius. 

 M. rufo-testaceus, pube grisea nebulosa brevissiina tectus; 

 elytris leviter punctatis, postice fere obsoletis, apicibus trun- 

 catis, intns sinuatis, in spinam longam externe productis ; an- 

 tennis sub-annulatis. 

 Mab. — Batchian, Bouru ?, Saylee?, Gilolo? 

 Perhaps only a variety of M. captiosus, but different in colour, in 

 pubescence — which is thinner, the varying grey tints forming
