This insect seems to resemble M. simoni, Boliv., from Venezuela, but it has much 

 narrower elytra, The short pronotum is characteristic of M. aridifolia, as well as the 

 strong sulcus which excavates the metazona. This sulcus is not the typical one (which 

 is obliterated in Mimetica), but a groove formed by the upcurving of the metazona. 



7. Mimetica siccifolia, sp. n. (Tab. XXII. figg. 14-16.) 



6 . Statura M. mortuifolice. Fusco-castanea, fusco-punctata. Pronotum granulosum, postice latiuscule pro- 

 ductum, obtuse bilobatum. Elytra brevia, apice angulata, haud caudata in parte tertia latitudine maxima, 

 vena humerali ultra medium divergente. Campus marginalis ultra medium profunde irregulariter sinuatus, 

 margine antico crenulato ; margine postico apice toto integro, in medio recto ; campo posteriore ultra 

 medium macula discoidali trigonali hyalina necnon alteris 1-3 minoribus instructo. Pedes frequenter 

 fusco-punctati. 



Var. a. Elytra apice rotundata, crenulata. — b. Elytra apice excisa, breviter caudata. — c. Elytra maculis
