visible even in Clark's type, though he omitted to notice this in his 

 description. The postei'ior coxae have a rectangular plate at the base 

 Avithin, as in the type of Scirfes, S. liemisjyliaericvs L.. and the present 

 insect therefore does not accord with the description and figure of the 

 genus Ora Clark, taken from O. iroherti Guer., given by me in the 

 ** Biologia," the last-named species wanting the coxal lamella. 



2. — Scirtes Jlavomaculatiis, n. sp. 



Broad-oval, rather convex, very shining, rather sparsely pubescent ; nigro- 

 piceous, the sides of the prothor.ix broadly, and six spots on each elytron — one 

 adjacent to the scutelkim, two transversely placed at about the basal third (the 

 outer one transverse and reaching the lateral margin, the inner one smaller and 

 near the suture), two others below these (obsolete in one specimeu), and one 

 near the apex, — flavous, the antennae, palpi, and legs, the under surface in 

 part, and a triangular mark on the front of the head (wanting in one example) 

 testaceous ; the elytra closely, rather coarsely, the rest of the upper surface 

 much more finely, punctate. Head broad ; antennae long, slender, joints 2 and 

 3 short, equal. Prothorax rapidly, arcuately narrowed from the base, hollowed 

 in front opposite the eyes. El3^tra with an indication of a faintly impressed 

 sutural groove, rounded at the apex, sharply margined. Posterior coxal plates 

 subquadrate. Posterior legs long, the tibiae feebly curved, the upper spur 

 much shorter than the first tarsal joint. 



Var. The prothorax wholly infuscate, the flavous elytral markings reduced 

 to a narrow interrupted fascia below the base. ( 9 •) 



Length 4-4y\j , breadth 2f-3mm. 



Hah. Brazil, Rio de Janeiro (Fri/). 



Three examples, varying in the development of the flavous markings 

 on the elytra, the one ( 9 ) with six sharpl}^- defined spots on each wing- 

 case taken as the type. Yerj near S. grayi, but with a different system 

 of coloration, and the elytra less rounded at the sides. The present 

 species might easily be mistaken for a Coccinellid. aS*. variegatus Guer., 

 from Cayenne ?, seems to be a somewhat similar insect. 



3. — Scirtes multiguttatus, n. sp. *" 



Oval, shining, finely pubescent ; piceous, the head with an oblong patch 

 on each side in front, the prothorax (a transverse piceous fascia on the disc 

 excepted), and the suture and nine sharply defined spots or streaks on each 

 elytron — two, oblique, on the disc near the base, a humeral streak curving 

 inwards posteriorly, an oval spot below this near the suture, three spots 

 arranged in a curved fascia beyond the middle, and two, transversely confluent, 

 near the apex — yellow ; the basal joints of the antennae, and the legs iu part, 

 le^aceous ; closely, minutely, the elytra conspicuously, punctate. Head rather 

 small; antennae moderately long, rather slender, joint 3 minute, shorter than 2, 

 4-10 gradually decreasing in length. Prothorax arcuately narrowed from the 

 base, hollowed iu front opposite the eyes. Elytra rather convex, without
