the Coleopterous Family Erotylidce. (125) 501 



The coloration resembles that of Scaph. zigcfna; and is difficult 

 to describe; in the type there is a humei-al and basal spot, a very- 

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

 interrupted) fascia in the middle, an in-egular 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. 



Presternum convex, emarginate behind; no coxal lines; meta- 

 sternum with the sides strongly punctate ; anterior tarsi stout, 8th 

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



Brachysphoenus 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 marginibus 

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

 tato-striatis, interstitiis parcissime pimctatis ; scutello uigro. L. 

 41in. 



Amazons (Bates). 



Anterior tarsi dilated, joints 1 — 3 subequal, antennje with a 3- 

 jointed club. Presternum very convex, emarginate behind; no 

 coxal lines. The coloui-ing of the elytra is pi'obably 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 ^ on the disc, connected from the middle with 

 a common fascia at 3 (which is dilated on the disc, and again at 

 the suture), and the apical \ black.
