DiSONYCHA AUSTRIA CAj Schauf. 



San Esteban. 



DiSONYCHA GLABRATA, Fabr. 



La Guaira and San Esteban. 



DiSONYCHA L^EVIPENNIS, D. Sp. 



Testaceous ; the antennae, apex of the tibiae, and the tarsi black ; 

 thorax impunctate ; elytra purplish blue, impunctate. 



Length 2 lines. 



Head impunctate, testaceous, with a single deep fovea near tlie 

 inner margin of the eyes ; the frontal elevations absent ; the clypeus 

 broad and but little raised; antennae short and robust, entirely black, 

 the first joint testaceous below, the fourth longer than the third, this 

 latter distinctly longer than the second joint ; thorax transverse, 

 nearly three times broader than long, pale testaceous, entirely im- 

 punctate, with an obscure transverse depression near the base, the 

 posterior angles oblique ; scutellum much broader than long, piceous ; 

 elytra entirely impunctate, purplish blue ; underside and legs testa- 

 ceous ; the tibise (their base excepted) and tarsi black. 



Caracas. A single specimen. 



D. Icevipennis seems allied toD. eximia, Harold, from which it differs 

 in the colour of the antennae and in the presence of a thoracic groove. 

 D. steinheili is another closely allied species, but has the vertex of 

 the head aeneous and the basal joints of the antennae pale. The elytra 

 in B. Icsvipennis, although impunctate, are unevenly rugose, but it is 

 possible that in the specimen obtained this is abnormal or accidental. 



Systena s-littera, Liun. 

 Caracas. 



EpITRIX FULVICORNIS, U. Sp. 



Black ; thorax and legs, the posterior femora excepted, flavous ; 

 thorax very strongly punctured ; elytra with the base swollen, deeply 

 punctate-striate. 



Length g line. 



Head piceous, impunctate ; the frontal tubercles forming narrow 

 oblique ridges; antennae flavous, the third and fourth joints equal; 

 thorax nearly twice as broad as long, rather convex, the sides nearly 

 straight, the anterior angles oblique, the surface deeply and rather 

 closely punctured, with a slight bronze tint, the median lobe strongly 

 produced and rounded ; the sulcation not very deep, except at the 

 sides, slightly sinuate, the space below it more remotely punctured : 

 elytra with the basal portion strongly raised, the latter bounded 

 below by a transverse groove, the punctured rows deep and regular, 

 visible "to the apex ; the interstices costate at the sides, clothed 

 sparingly with a few hairs. 



San Esteban and Caracas. 



E.fulvicornis seems to differ from its rather numerous congeners
