306 Longicornia Malayana. 



very dense tomentum, but especially two large spots, one before 

 the other behind the middle, each of these spots formed by the 

 junction, or very nearly the junction of two, but variable even 

 in the same specimen ; the example from Ceram has the spots pure 

 white ; body beneath and legs with a close fulvous-grey pile ; 

 antennas brownish, minutely pubescent. 



Length 11 lines, of the antennae (^) 33 lines. 



Trysimia rugicollis, 



T. fusca, leviter griseo-pubescens ; prothorace transversim 

 lineato ; elytris albo-irroratis. 



HaB. — Macassar. 



Brown, with a short sparse greyish pile ; frontal impressed line 

 terminating between the eyes in an interrupted transverse ridge, 

 an oblique glabrous black mark at the angles of the mouth ; pro- 

 thorax transverse, two apical and two basal grooves, between the 

 two series numerous transverse contorted lines, the centre and a 

 spot on each side dark brown; scutellum rounded ; elytra with a 

 few granules on the shoulders, thickly punctured at the base, the 

 punctures disappearing near the apex, speckled with small densely 

 tomentose white spots; body, legs and antennae yellowish-brown, 

 finely pubescent. 



Length 8 lines, of the antennae ( J ) 11 lines. 



Nepiielotus. 

 Ca;)wf antice quadratum ; clypeo truncato ; tuberibus antenni- 

 feris validis, basi separatis. Mandibulce breves. Oculi 

 mediocres, lobo inferiore verticali vel angustato. Anlenntje 

 elongatae ; scapo sub-cylindrico ; articulo tertio scapo longiore ; 

 quarto breviore ; sequentibus sub-aequalibus. Prothorax regu- 

 laris, cylindricus, lateraliter dente minuto instructiis. Elytra 

 sub-angustata, humeris in dentem productis, apicibus rotun- 

 datis. Pedes mediocres, in utroque sexu aequales ; femora 

 modice incrassata ; tarsi articulo ultimo elongato. Pro- 

 sternum simplex. Mesosternum baud dentatum. 

 The prothoracic spine in this genus is reduced to a mere point ; 

 the legs are equal in botli sexes ; and the claw-joint is of large size, 

 but this seems to be a character of less importance among these 

 genera than it is in other groups. In other respects the genus is near 

 Monochamus, except that the head is more quadrate in front.
