slope of Mexico and Guatemala; but v,\ih very different niai-kiiigs, 

 "Which are not unlike those of D. var/'er/afa Jac. from N.W. Mexico, an 

 insect with smoother elytra and a non-foveate prothorax. 



Epitrix paludicola, n. sp. 



Short oval, convex, shiniiiir, pliibrous above, finely pubescent beneath ; 

 nigro-eaenileous, the head and j)rotlioiax greenish, the antennae, under surfai'e, 

 and legs black, the basal joints of the antennae and the third tarsal joint pailly 

 testaceous or nifescent. Head almost smooth, the eyes prominent ; antennae 

 long. Prothorax narrowing from the base, somewhat closel}'^, hnely, con- 

 spicuously punctate, with a short, deep, longitudinal sulcus on each side at the 

 base, the two sulci coniiectetl anteriorly by a fauit transverse groove, the mar- 

 ginal carina oblic[uely thickened on each side at the apex. Elytra with 

 rows of moderately coarse or rather tine punctures placed in faint striae, tlie 

 interstices flat, almost smooth, llie disc transversely depressed below the base. 



Length -l^x-'-h breadth 1-J-U mm. 



Hah. Costa Hica, Juan Yinas (P. P. Calvert : 5.X.1909). 



Two specimens, found in the same locality as Hi/pocoeliodes sex- 

 nodosiis. Nearly related to E. violacea and E. jmncticoUis Jac. from 

 Guatemala, but with longer and sharper longitudinal grooves at the base 

 of the prothorax, the prothorax itself somewhat closely punctured. 

 E. cyanella, carinata, caeruleata, and segregata Baly are similarly 

 coloured S. American insects. 



Homalispa sidcicollis, n. sp. 



Elongate oval, shining ; head and prothorax rufo-testaceous, the eyes and 

 antennae (the partly rufescent basal joint and tip excepted) black, the scutellnm 

 1 iceous, the elytra metallic blue, the legs testaceous, the metastenuim and 

 abdomen varying in colour from almost wlioUy black to testaceous with the 

 medium portion broadly infuscate. Head smooth ; antennae rather more than 

 half the length of the body, joints 1 and 2 short, subequal, 3-10 moderately 

 elongate, 11 much longer than 10. Prothorax strong!}^ transverse, convex on 

 the disc, deeply excavate within the narrowly reflexed lateral margins to 

 near the apex, the sides parallel at the base and arcuately converging 

 anteriorly, the hind angles sharp; the surface almost smooth, except aL'iig 

 the abbreviated, finely pinictured, shallow, transverse groove at the ba>e. 

 Elytra moderately broad, subparallel in their median third, compressed 

 at the sides below the humeri, and bluntly rounded at the tip ; seriato- 

 punctate, the punctures fine on the disc, becoming coarser towards the sides, 

 the interstices flat, obsoletely punctulate. Beneath faintly punetulate and 

 flnely pubescent. 



Length 3^-3^, breath U-lf mm.
