272 MR. M. JACOBY ON COLEOPTERA [May 21, 
DISONYCHA AUSTRIACA, Schauf. 
San Esteban. 
DisonyCHA GLABRATA, Fabr. 
La Guaira and San Esteban. 
DisoNYCHA LEVIPENNIS, 0. sp. 
Testaceous; the antennze, apex of the tibia, and the tarsi black ; 
thorax impunctate; elytra purplish blue, impunctate. 
Length 2 lines. 
Head impunctate, testaceous, with a single deep fovea near the 
inner margin of the eyes; the frontal elevations absent ; the clypeus 
broad and but little raised ; anteunze 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 tibiee (their base excepted) and tarsi black. 
Caracas. A single specimen. 
D. levipennis seems allied to D. eximia, Harold, from which it differs 
in the colour of the antennze and in the presence of a thoracic groove. 
D. steinheili is another closely allied species, but has the vertex of 
the head zeneous and the basal joints of the antenne pale. The elytra 
in D. levipennis, although impunctate, are unevenly rugose, but it is 
possible that in the specimen obtained this is abnormal or accidental. 
SYSTENA S-LITTERA, Linn. 
Caracas. 
Epirrix FULVICORNIS, 0. sp. 
Black ; thorax and legs, the posterior femora excepted, flavous ; 
thorax very strongly punctured ; elytra with the base swollen, deeply 
punctate-striate. 
Length 3 line. 
Head piceous, impunctate ; the frontal tubercles forming narrow 
oblique ridges ; antennz 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. 
Zi. fulvicornis seems to differ from its rather numerous congeners
