ALLOCITROMA. 193 



punctate. Thorax transverse ; the anterior angles depressed ; the 

 sides marginate ; the surface is punctate, more distinctly at the base : 

 a postmedial transverse depression (which does not reach the basal 

 line) extends to the margination ; in this depression are two con- 

 tiguous circular spots. Scutellum sufficiently large, triangular, fus- 

 cous. Elytra tolerably robust, coarsely punctate-striate ; in the 

 centre of the antemedial, and also of the postmedial part of the 

 elytra (between the second and the sixth stria?) is a large insulated 

 black macula (that nearer to the shoulders subcircular, that at the 

 apex oval or elongate). Antenna? robust, short, incrassated towards 

 the base, fuscous, with the sixth to the ninth joints back. Legs ro- 

 bust, ferrugineous. 



Brazil. 



A.festivum differs from all other species, except the preceding, in 

 its four distinct markings on the elytra.

A. ovation, robustwn, Jiavum ; capite depresso, antice hand attenu- 

 ato, inter oeidos in forma literce T foveolato, impunctato (ad ba- 

 sin punetis minutis notato), rufo ; thorace transverso, rectangu- 

 lar!, angulis distinctis marginatis, flavis ; elytris punetis veluti 

 in striis dispositis, flavis, ad basin rufo suffusis ; maculis sex 

 nigris, ad humeros duo?, ad scutellum duce circulares, duasque 

 p>ost medium transversa ; antennis robustis, subincrassatis ; pe- 

 dibus flavis, tarsis anterioribus (tibiisque supeme visis) fuscis.

Ovate, robust, flavous. Head large, very slightly produced, de- 

 pressed ; eyes tolerably large, but not extending laterally to the line 

 of the anterior angles of the thorax ; between the eyes is a very 

 distinct T-shaped fovea, the longitudinal line of which is extended 

 obsoletely upwards towards the base ; the surface of the head is im- 

 punctate (with a few scattered minute punctures at the base) and 

 rufous. Thorax transverse, rectangular, slightly compressed towards 

 the base ; the anterior angles are prominent and subacute ; the sides 

 distinctly marginate ; the posterior angles distinct ; the surface is 

 equate ('without any depressions), impunctate, and in colour flavous. 

 Scutellum distinct, triangular, large, impunctate, flavous. Elytra 

 broad, robust, with rows of large and shallow strioe-like punctures ; 

 a slight and broad depression extends transversely, a little in front of 

 the middle ; the surface is flavous ; the apex is broadly suffused with 

 rufous ; six large black spots are distributed on the surface : one, 

 on either side, at the humeral angle, a second (larger and circular) 

 near the scutellum, and the third (larger still and transverse) post-
