366 GUY A. K. MARSHALL. 



Emperorrhinus defoliator, sp. nov. (fig. 1). 



Black, densely clothed with mingled black and bright metallic green scaling ; head 

 and rostrum green ; prothorax green, with a broad central black stripe ; elytra 

 variable, but with the green and black scaling fairly equally distributed in alternating 

 small subquadrate patches on the dorsal intervals ; there is often a somewhat large 

 black patch near the base on intervals 3 to 6,^and occasionally the black scales greatly 

 predominate. 



Fig. 1. Head of Emperorrhinus defoliator, Mshl., sp. n. 



Head finely striolate longitudinally, the fore head quite twice as broad as the space- 

 between the scrobes, the eyes moderately convex. Rostrum with the left side 

 (excluding the mandible) somewhat shorter than the basal width, distinctly narrowed 

 from the base to apex, the sides being almost straight ; the interscrobal area almost 

 plane, finely striolate beneath the scaling, and with a fine central carina in the 

 anterior part. Antennae reddish brown ; the funicle with the two basal joints 

 subequal, or the first very slightly longer, the remaining five subequal and 

 much longer than broad. Prothorax transverse, truncate at base and apex, 

 which are of equal width, the sides rounded only in the middle, markedly constricted 

 in front and behind ; the dorsum rather uneven, without any central furrow or 

 carina, the somewhat rugose punctures normally hidden by the scaling, the setae, 

 suberect and all directed forwards. Elytra much broader than the prothorax at the 

 shoulders, which are rounded rectangular, parallel-sided in the male and slightly 

 dilated behind the middle in the female, the apices jointly rounded, and the dorsal 

 outline only shghtly convex ; the shallow striae not hidden by the scaling and con- 

 taining shallow punctures, the intervals almost plane, shining and impunctate ; the 

 scales small, convex and subcircular, the green ones for the most part contiguous, 

 the black more sparse, so that the shining surface is partly visible ; the setae slender, 

 long, dark and erect. Legs red-brown, the femora darker, with recumbent pale 

 setae and scattered green scales. 



Length, 2|-3J mm. ; width, 1 J-IJ mm.

This species superficially resembles such small Myllocerus as M. dorsatus, F., and 

 M. pretiosus, Est., but may be readily distinguished by the abnormal structure of the 

 rostrum. I have examined 36 specimens.
