colour distinctions also appear to be reliable ; in C. splendidulus the anterior black 

 marking on the elytra is merely a longitudinal patch without anchor-like arms, the 

 succeeding pink area extends right up to the shoulder (whereas it always ceases long 

 before the shoulder in C. indicus), and the tibiae are entirely testaceous. The colouring 

 of C. indicus appears to be relatively constant in a long series of specimens. 



This weevil is recorded as attacking Tamarix indica, and most of the palaearctic 

 species appear to be specially attached to plants of this genus. 



Ceuthorrhynchus portulacae, sp. nov. (fig. 2). 



Colour black or dark brown, with the antennae, tarsi, tibiae and apex of the rostrum 

 paler ; fairly densely clothed with elongate, truncate, slightly elevated, greyish and 

 brownish scales, which are mingled irregularly and through which the shiny integu- 

 ment is easily visible ; the pronotum has in the basal half a central stripe composed 

 of much broader ovate whitish scales ; this stripe is continued on to the first interval 

 of the elytra, extending for about one-third of its length, but here the scales are more 

 dense and often of a yellomsh or brownish tinge. 



Fig. 2. Ceuthorrhynchus portulacae, Mshl., sp. n. 



Head with coarse confluent punctation, the forehead broad and flat ; the scales 

 narrower than those on the pronotum, elevated along the margin of the eyes but 

 recumbent elsewhere, those on the forehead directed backwards, those on the vertex 

 directed forwards. Rostrum comparatively stout and unusually short, scarcely as 

 long as the prothorax in the 5? shorter in the ^, gently curved and gradually dilated 

 from base to apex, being there about as broad as the apical portion of the front femur ; 

 the upper surface coarsely punctate and with sparse narrow scales as far as the 

 antennae, beyond that smooth and almost impunctate. Antennae testaceous, inserted 

 well beyond the middle of the rostrum, the scape terminating in a sharp point ; the 

 funicle with joint 1 longer and much broader than the others, 2-4 much longer than 

 broad and diminishing progressively in length, 5-»7 subequal and about as long as 

 broad. Prothorax transverse, broadest near the base and thence strongly narrowed 

 to the apex, the sides being almost straight, the front margin forming an elevated
