tudinal median depression, deeper behind than in front, and on 

 each side of which is a large, moderately deep, round depression, 

 sparsely, deeply and rather regularly punctate on the disk, becom- 

 ing coarsely, irregularly rugose toward the sides, the rugae long, 

 strongly elevated, and widely separated ; intervals finely and densely 

 granulose. Scutellum very small, triangular, the sides about equal 

 in length. Elytra distinctly wider than pronotum 'at base; sides 

 broadly rounded at humeral angles, nearly parallel to behind middle, 

 then obliquely attenuate to the tips, which are rather acute; lateral 

 margins very coarsely serrate to near middle; each elytron strongly 

 angularly lobed at base, with a feeble transverse basal impression, 

 and four more or less distinct sinnuate longitudinal costae, none of 

 which extend to the apex; surface densely, deeply and irregularly 

 punctate, the punctures becoming confluent toward the sides; inter- 

 vals densely and rather coarsely granulose; each elytron ornated 

 with aeneous markings, which are very narrowly margined with 

 cyaneous and arranged as follows: An elongate circle enclosing a 

 dark area at base and extending backward forming the letter C, 

 w^ith the opening toward the suture; at basal third a broad trans- 

 verse fascia, forming posteriorly the letter W between the first and 

 second costae, and then extending transversely to the suture, and 

 forward along the suture to the base ; at the middle there is a very 

 irregular zigzag fascia extending from the latei-'al margin and form- 

 ing the letter M between the first and second costa, then obliquely 

 backward to the suture 'at apical third, and following the suture to 

 apex, where it is sometimes connected to a narrow band along the 

 lateral margin, which extends forward to the apical third; there is 

 also an oblong spot behind the humeral angle. Abdomen beneath 

 moderately convex, sparsely but not very deeply punctate; intervals 

 smooth and shining ; last segment more densely punctured posteriorly, 

 with the apex broadly sinuate and armed on each side with a 

 tooth. Presternum feebly convex, broadly truncate and declivous in 

 front: surface sparsely and rather coarsely punctate, becoming ir- 

 regularly striolate toward the sides; prosternal process feebly con- 

 vex, strongly expanded behind the coxal cavities, the sides very 

 long and acute, and extending between the anterior and middle 

 coxae, the median tooth long and acute at apex. Posterior tibiae 

 with a dense line of very long fine hairs on the inner margin. 



Length, 15 mm. ; width, 6 mm. 



This species was described by Schonherr from Brazil, and the 

 above description was made from a specimen donated to the United 

 states National Museum by the British Museum, which was col- 

 lected at Jatahy, Brazil, and determined by Kerremans as fulminata 

 Schonherr. Actenodes cyanura was described by Chevrolat from 

 Cayenne, and has been placed as a synonym of fulminata by Kerre-
