type was a little larger (length 4|, breadth 83 mm.), but the other par- 

 ticulars given by him apply to the insect before me. The upper surface 

 is smoother than in 0. marmorata and the allied Centi-al American 

 forms, the puncturing of the elytra being extremely fine and dense, and 

 that of the prothoi-ax only visible under a high magnifying-power.

Described from two specimens from Panama, three others from 

 additional localities having since come under my notice. A very 

 similar form was found in Batchian by A. R. Wallace, see infra. 

 No. 15. 



4. — Ora gamma, n. sp. 



Elliptic, depressed, shining, thickly pubescent ; testaceous, the eyes black, 

 the elytra with the suture, outer margin in part, apex, and an interrupted post- 

 median fascia (formed by a Y-shaped mark near the suture, a streak exterior 

 to it, and an oblique lateral patch) flavous, the flavous markings preceded by a 

 narrow, sharply angulate, piceous fascia and followed by four piceous streaks, 

 the disc in front of the dark fascia to near the base slightly infuscate ; the 

 elytra densely, finely, rugosely punctate, with slightly coarser punctures inter- 

 mixed, the rest of the upper surface smoother. Head small ; antennae rather 

 slender, long, joints 2 and 3 short, equal in length, the others long, filiform. 

 Protborax comparatively narrow, arcuately narrowing from the base, hollowed 

 in front opposite the eyes, the anterior angles obtuse. Elytra long, rounded 

 and explanate at the sides, somewhat acuminate at the tip, with a distinct 

 sutural groove and indications of three feeble costae. Posterior coxae without 

 plate. [Posterior legs wanting.] 



Length 4i, breadth 2| mm. 



Hah. Brazil, Rio de Janeiro {Fry). 



One specimen. Easily recognizable by the sharply-defined elytral 

 markings, which consist of two interrupted, angulate, blackish, post- 

 median fasciae, almost enclosing a flavous one, the latter formed by a 

 Y-shaped streak near the suture and some oblique patches exterior to it. 

 The Eastern O. picta and O. atrosiynata (No. 17), the S. African 

 O. 20-guttafa (No. 12), and the Bolivian 0. {Scyrtes) lignea, are 

 somewhat similar sharply maculate insects.
