RHYNCHOPUORUS LOIWTIS 179 



Oil the pronotum and the longitudinal and transverse rid- 

 ges between the large and deeply impressed punctures or 

 pits on the back of the elytra are scaleless, possibly from 

 abrasion. 



This species may be easily distinguished from E. pau- 

 peratus Fabr. (with which it shows a striking resemblance) 

 by the somewhat longer and narrower head and rostrum , 

 but especially by the longer and more slender antennae. 



Two male specimens from Kotta Zuydewiju near Solok 

 (J. H. Schagen van Leeuwen). 



3. Rhynchophorus lob a t us ^ n. sp. cf- 



Length (the rostrum included) 37 mm., width of the 

 shoulders of the elytra 14 mm. — Deep black, smooth 

 and subshining. 



The scape of the antennae and the rostrum are finely 

 and remotely punctured; the latter is slightly curved at 

 its apical half, and a little wider and distinctly convex 

 at its base ; its uppersurface before the convex portion is 

 provided with two longitudinal ridges formed by more or 

 less confluent tubercles , which end at a compressed median 

 tubercle placed a little before the apex of the rostrum. 

 Between the eyes a small rounded fovea is present. 



The prothorax is regularly convex , and about one and 

 a half as long as broad; its sides are regularly rounded 

 anteriorly , nearly parallel towards the base which is nar- 

 rowly margined; the basal lobe has the shape of a 

 triangle with rounded tip ; it is separated from the 

 disk of the thorax by a transverse slightly curved impres- 

 sion and provided with a few rather shallow punctures. 

 The contracted anterior portion of the thorax is well- 

 defined and provided with a few rather large punctures. 

 On the disk , which shows an exceedingly delicate sculpture 

 intermixed with fine punctures , a trace of a raised line 

 may be observed along its whole length. The scutellum 

 is flat, narrow and elongate.
