This appears to be a very distinct species, strongly marked 

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

 suggest an Anthobosca allied 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 steel-blue 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 punctured;, 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. 



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



Ml). 



The only specimen I have seen from Assam has the head 

 distinctly longer than biT)ad, loliger behind the eyes than in the 

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

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

 slope. The differences will probably prove to be subspecific. 

 Mr. Bell informed me that he bred this species from the larva of 

 a longicorn beetle i

c? . Antennte stout, a little longer than the thorax and median 

 segment combined. Front t-ugose, vertex sparsely pulictured. 

 Pt-onotum transversely rugulose, much longer than the meso- 

 iiotum-, the sides almost parallel. Head slightly narroWed and 

 produced frota behind the eyes. Thorax and median segment 

 i-ugose, the median segment distinctly margined posteriorly and 

 vertically tt-uncate. First abd&minal segment vertically truncate 

 anteriorly. With a distinct transverse carina above the base of 

 the truncation, attached to the abdomen by a very short petiole, 

 nearly as broad as the Second segment, the sides pat-allel. 

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

 iarea. ^ Second abscissa of the radius as long as the 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-
