CORESTETHA. 
(Doreadionine.) 
Caput parvum, inter antennas latum, fronte transversa; labrum 
amplum, antice rotundatum. Ocule late emarginati, fortiter 
granulati. Antenne corpore vix longiores, articulo basali sub- 
pyriformi, tertio longiusculo, recto, czeteris gradatim brevioribus. 
Prothorax oblongus, cylindricus, capite haud latior. Scutellum 
nullum. Elytra oblonga, prothorace haud latiora. Pedes breves ; 
femora valida ; tebie omnes breves, intermediz profunde emargi- 
nate, posteriores haud compresse. Core antice globose, sejunctee. 
Pro- et mesosterna elongata. Abdomen segmento basali duobus 
sequentibus conjunctim longiore. 
Closely allied to Mesohita; but while the posterior tibie are 
scarcely as long as the tarsus, and terete, in Mesolita they are 
twice as long and compressed. ‘The eyes have fewer facets 
than in any other species I have examined: in Mesolita trans- 
versa they are rather finely, while in M. lineolata they are 
somewhat coarsely faceted. This is therefore one of those 
genera in which the facets of the eyes have only a specific 
value. The species described below varies in the testaceous 
becoming more or less of a smoky brown, like the general 
colour. 
Corestetha insularis. 
C. angusta, infuscata, subtiliter pubescens, supra confertim tenuiter 
punctulata ;° capite antice transverso; antennis testaceis, nigro 
annulatis, articulo basali oblongo-pyriformi ; prothorace latitudine 
sesquilongiore ; elytris fere obsolete striatis, fasciis duabus sub- 
testaceis, aliquando ad suturam interruptis, una basali, altera 
pone medium, obsitis ; pedibus subtestaceis, vel infuscatis. Long. 
13-2 lin.

Monochamus fulvicornis. 
M. angustus, fuscus ; antennis ( ¢ ) corpore plus duplo longioribus, 
clare fulvis, articulo basali excepto; capite griseo-pubescente, 
impunctato, in medio longitudinaliter sulcato ; tuberculis antenni- 
feris validis ; prothorace transyerso, in medio leviter punctulato, 
spina laterali minus robusto; elytris modice elongatis, postice 
angustioribus, apicibus rotundatis, supra fere squatis, modice 
punctulatis ; corpore infra pedibusque breviter griseo tomentosis ; 
tibiis anticis haud elongatis, flexuosis. Long. & lin.
