222 REVISION OF rrEROHEL^.US (contd.) AND SARAGUS, E'lC, 



on foliage. It is allied to .4. rwptum Pasc, from which it 

 differs in its shorter and more convex shape, its brightly var- 

 nished surface, bright red antennae and tarsi, its prothorax 

 much less narrowed at base, and its very unequal elytral 

 punctures. I have a specimen of .4. i-wptum Pasc, which I 

 compared with the type, whose dimensions are 15 x 4-5 mm. 

 .4. arboricola belongs to my Section ii., Subsection C. 



Adelium cyaneum, n.sp. 



Subparallel, rather flat, blue varying from violet to pea- 

 cock blue-green, very nitid and smooth above, underside 

 nitid coppery-bronze; oral organs, anteinue, and tarsi fuscou.s. 



Head strongly punctate, punctures larger on forehead, 

 labrum emarginate ; epistoma convex and round in front, 

 limiting suture straight and deeply impressed, continued 

 obliquely backwards to eyes, front slightly depressed : an- 

 tennae short, not reaching base of prothorax, third joint little 

 longer than fourth, 4-8 successively wider, obconic, 9-10 subtrian- 

 gular, eleventh largest, ovate. Prothorax, 2-5 x 4 mm. in <^;'l y. 3-5 

 mm. in ^\ almost semicircular at apex, truncate at base, widest at 

 middle,equally wideat base and apex, all angles obtuse, sides widely 

 rounded, sinuate near base, with a thin raised border throughout, 

 margins slightly explanate but not differentiated in sculpture 

 from disc, the latter uniformly closely and finely punctate, 

 a slight foveate depression on each side at base, and elongate 

 lateral foveae, the male specimen with a very faint indication 

 of a central line. Scuteflnni rather widely triangular. Elytra 

 truncate ovate, slightly convex, wider than prothorax at 

 base, and rather more than twice as long, shoulders nearly 

 square, not widened behind, punctate-striate, each elytron 

 with ten well markecT striae, intervals flat near suture, be- 

 coming strongly convex at sides, punctures in sti'iae small, 

 close, and almost concealed, but forming little notches on 

 sides of intervals, these also minutely punctate. Epipleurce 

 coarsely, prosternum and parapleurae sparingly and more 

 finely, abdomen and legs minutely punctate ; intercoxal pro-
