BRACHYSPHCENUS. 125 



The coloration resembles thcat of Scaph. zujcvna; and is difficnlt 

 to describe; in the type there is a humeral and basal spot, a very 

 waved (but entire) fascia at \, an externally abbreviated (and often 

 interrupted) fascia in the middle, an irregular interrupted (but 

 starting from the margin) fascia at % and an irregular dentate 

 line at ^, all black; these however vary so much in their intensity 

 as to be very difficult to recognize sometimes. 



Prosternum convex, emai-ginate behind; no coxal lines; meta- 

 stei-num with the sides strongly })unctate ; anterior tarsi stout, 8th 

 joint longer than the 2nd; antennae with a 3-jointed club. 



Brachysphcenus luteopictus, sp. n. 



Oblongo-ovatus, rufo-testaceus, nitidus, capite postice nigro, 

 clypeo punctato; thorace sat lato, convexo, lateribus rotundatis, 

 antice semicirculariter emarginato, nigro, vix punctato, lateribus 

 anguste rufo-testaceis ; elytris ochraceo-flavis, sutura marginibiis 

 epipleurisque rufo-testaceis, nigro-pictis, obsolete gemellato-punc- 

 tato-striatis, interstitiis parcissime punctatis ; scutello nigro. L.

Amazons (Bates). 



Anterior tarsi dilated, joints 1 — 3 subequal, antennae w^ith a 3- 

 jointed club. Prosternum very convex, emarginate behind; no 

 coxal lines. The colouring of the elytra is probably variable : in 

 the type there is a small dot in the middle of the base, a well- 

 defined cordate common spot below the scutellum, an irregular 

 transverse mark at I on the disc, connected from the middle with 

 a common fascia at g (which is dilated on the disc, and again at 

 the suture), and the apical \ black,
