11. Allochroma assimile. 



A. oblongo-ovatum, latum, robust inn, tenuiter subpubescens, jlavo- 

 fi rrui/i neum ; thorace quadrato, ad basin transverse depresso ; 

 ( 1 i/tris pvnctato-striatis, ante medium subdepressis, ad latera et ad 

 basin siibjmbescentibus ; antennis ad apicem dilatatis, art. 1-5 

 Jlavo-rujzs, 6-8 rufo-piceis (cceteri desunt) ; pedibus anterioribus 

 flavis, posticis rufo-flavis. 



Long. corp. 1 lin., lat. ± lin. 



Oblong-ovate, broad, robust, finely subpubescent (not so distinctly 

 and generally as in A. nigro-marginatum) ; the colour is flavo- 

 ferrugineous throughout. Head short, transverse, slightly produced ; 

 above the base of the antennae, and between the eyes, are two obso- 

 lete obliquely-transverse carinations, while between them is a third, 

 medial, reaching to the base of the head ; the surface is finely punc- 

 tate. Thorax quadrate ; the anterior angles subacute and much 

 depressed ; the sides marginate ; the surface more distinctly pubes- 

 cent than in A. nigro-marginatum ; the base is broadly and trans- 

 versely subdepressed. Scutellum small, triangular, flavous. Elytra 

 broad, robust, subparallel, finely punctate-striate, the striae being 

 almost obsolete; finely pubescent at the sides and apex, and very 

 sparingly throughout the whole surface (more sparingly than in the 

 former species) ; a broad and faint transversely oblique depression 

 extends antemedially in the direction of the shoulders. Antennae 

 tolerably robust, slightly dilated towards the middle and apex; joints 

 one to five flavo-rufous, six to eight rufo-piceous (the rest are 

 wanting in the example before me). Legs : the anterior flavous ; 

 the postical rufo-flavous. 



This species is at first sight closely allied to A. nigro-marginatum ; 

 it may without difficulty be separated by the quadrate form of its 

 thorax, and also by its somewhat less distinct pubescence.
