436 Longicornia Malayana. 



A very narrowly elongate and well-marked form. In Mr. 

 Wallace's notes it is said to fly slowly and undulatingly, like an 

 Ichneumon-fly. 



Oberea insensU'is. 

 O. subangustata, linearis, fulvescens ; elytris apicem versus ad 

 latera infuscatis ; corpore infra pedibusque concoloribus, seg- 

 mento ultimo apice nigro. 

 //fl6.— Menado. 



Shorter than the last, and not quite so linear ; the legs longer, 

 the under surface entirely fulvescent, except the apex of the last 

 abdominal segment, which is black. 

 Length o\ lines. 



Oberea tenera. 

 O. subangustata, linearis, fulvescens; elytris modice elongntis, 

 latere apiceque nigrescentibus ; corpore infra pedibusque con- 

 coloribus. 

 Hab. — Macassar. 



Differs from the preceding in the greater length of the elytra, 

 which are blackish at the side and apex, in the greater length of 

 tlie posterior legs, the abdomen entirely fulvous, and the consi- 

 derably larger eye ; tiie prothorax has also several small scat- 

 tered punctures, very distinct under a lens, that do not exist in 

 O. insensilis ; both are undoubtedly quite distinct from the rest of 

 the species in the collection, and have the antennae consideral)!y 

 longer than the body. 

 Length G lines. 



Oberea del'icata. 

 O. angustata, linearis^ fulvescens ; elytris, basi excepta, nigris ; 

 corpore infra pedibusque fulvescentibus, segmentis duobus 

 ultimis nigrescentibus. 

 Hab. — Tondano. 



Narrowly linear, fulvescent ; elytra, except at the base, black- 

 ish ; head rather large ; prothorax a little longer than broad ; 

 elytra scarcely broader than the prothorax : body beneatii and 

 legs pure pale fulvous, the last two abdominal segments black ; 

 legs moderately long; antennae black, about the length of the 

 body. 



Length A ^ lines. 



This species reminds us of 0. tcnuata, but the elytra are con-
