*Elis (Mesa) picticollis Mor. 



Flesia piciicoUis Mor. Hor. Soc. Ent. Ross. xxiv. p, 624 (1890), $ . 



This appears to be a very distinct species, strongly marked 

 with yellow on the head, thorax, and abdomen. The colour wovild 

 suggest an Anthohosca alHed to A. arabica Turn., but the structure 

 of the apical abdominal segment and the indistinct striation of 

 the metapleurse render it unlikely that it belongs to that genus.

This fine species is easily distinguished by the large size 

 (19 mm.), the bright red head, and steehblue abdomen. The 

 wings are fusco-hyaline, flushed with purple, almost hyaline at 

 the base. The head is large, quadrate^ sparsely punctured, 

 smooth on the vertex ; pronotum coarsely punctvired, median 

 segment subconcave on the posterior slope ; sixth dorsal segment 

 strongly punctured. Second abscissa of the radius nearly as 

 long as the first and third combined. 



Hah. Borneo (typical) ; Dibrughar, Assam ; W. India [T. R. 

 Bdl). 



The only specimen I have seen from Assam has the head 

 distinctly longer than broad, lohger behind the eyes than in the 

 typical form, and the scape and three basal joints of the flagellum 

 are red ; the median segment is not at all concave on the posterior 

 slope. The differences will probably prove to be subspecific.

 a longicorn beetlei

•S . Antennpe stout^ a little longer than the thorax and median 

 segment combined. Front rugose, vertex sparsely punctured. 

 Plfonotum transversely rugulose, much longer than the meso- 

 iiotum, the sides almost parallel. Head slightly narrowed and 

 produced from behind the eyes. Thorax and median segment 

 rugose, the median segment distinctly margined posteriorly and 

 vertically truncate. First abdominal seglnent vertically truncate 

 anteriorly, with a distinct transverse caHna above the base of 

 the truncation, attached to the abdomeli By a very short petiole, 

 nearly as broad as the second segment-, the sides parallel. 

 Apical dorsal segment not iiicised at the apex. Without a pygidial 

 area. Second abscissa of the radivis as long as tho first and third 

 cDmbined. 



Black ; scape and four basal joints of the flagellum, clypeus, 

 and apex of the interantennal prominence dull ferruginous ; 

 abdomen glossed with steely blue. Wings hyaline ; fusco-
