in medio Iseviusculo ; elytris singulis lateraliter plagis duabus 

 vel tribus rotundatis nigris ornatis. 



Hah. — Macassar (and Manilla). 



Blackish, covered with a short fulvous-grey pubescence ; head 

 with a few minute punctures ; prolhorax with two round flattish 

 tubercles anteriorly, the apical and basal grooves well marked ; 

 elytra finely punctured, a few granules on the shoulders, three 

 brown patches (or sometimes two only) on each at the sides, occa- 

 sionally speckled, principally near the suture ; body beneath with 

 a slight fulvescent pubescence; legs and antennae black, with a de- 

 licate ashy pile. 



Length 12 ( ^ )— 9 lines ( ? ). 



Mr, Newman's type has three dark stripes on the prothorax. 



DiOCHARES. 



Caput antice transversum, tuberibus antenniferis validis, basi 

 remotis. Mand'ibulce validae. Oculi magni, lobo inferiore 

 rotundato. Antennce elongatae ; scapo cylindrico ; articulo 

 tertio scapo longiore ; quarto, quinto, et sexto sensim 

 brevioribus ; sequentibus sequalibus, ultimo exceptoelongato. 

 Prothorax sub-transversus, lateraliter valde spinosus. Elytra 

 ampla, humeris productis, apicibus plerumque sinuatis. 

 Pedes validi, antici (^) paulo longiores ; femora sub-incras- 

 sata. Mesosternum dentatum. 

 This genus is separated from Monochamus on account of its 

 widely-placed antennary tubers, large eyes, and toothed meso- 

 sternum ; and these characters, taken together, separate it also from 

 all other genera of Lamiince proposed in this work. The type was 

 long ago described by Olivier, but does not appear to have been re- 

 cognized by subsequent authors, except Fabricius, who gave it 

 another name ; it is very variable in colour. D. lugubris and D. 

 vnpluv'iatus are described from single specimens, and it is possible 

 that similar variations may occur in them. Monochamus ambi- 

 genus, Chev., also belongs to this genus.
