much wider than high, with a smooth arcuate impression abov<; the basal mar- 

 gin of the head; humeral angles very large, auricular, triangular, blunt, tips 

 extending slightly upward and forward ; below and in front of the humeral 

 angles a broad flap of the pronotum extending caudo-ventrad and partially 

 covering the sides of the pro- and mesothorax and the bases of the front 

 legs ; median carina strongly percurrent, brown in front of and black behind 

 the line of the humeral angles ; posterior process short, heavy, tectiform, blunt, 

 rounded. No part of the head visible from a strictly dorsal view. 



Tegmina about one third exposed for the basal two thirds of their lengths ; 

 dark brown; entirely opaque; veins indistinct; tips entirely hidden. 



Under surface of body tmiform brown; coxae and femora brown; tibiae 

 of first two pairs of legs yellow, of hind legs yellow on proximal half and 

 brown on distal half; tarsi of first two pairs of legs flavous, of hind legs very 

 dark brown. 



Length 4.5 mm.; width between tips of humeral angles 5 mm. ; width 

 across middle of pronotum 3 mm. 



Type : male. 



Locality: Para, Brazil. July 30, 1019 (Parish). 



All of the specimens are from the type locality and all are males. 



Shield-shaped, orange and black; humeral angles long and slightly 

 curved forward; tegmina about one third exposed, dark brown, entirely 

 opaque ; pronotum much produced backwards and downwards behind 

 the eyes in an extension which hides the bases of the front legs; under 

 surface of body brown ; legs yellow and black. 



Chelyoidea maculata new species. (PI. II, fig. n.) 



Head nearly quadrangular, mottled yellow and brown, very finely punctate, 

 not pubescent, basal area largely yellow, apical area brown with a diagonal 

 rectangular yellow patch on each side extending from below the ocelli to below 

 ithe eye and a perpendicular area on the clypeus ; dorsal margin sinuate ; eyes 

 !large, prominent, gray ; ocelli large, prominent, elevated, yellow, glassy, twice 

 :as far from each other as from the eyes and situated well above a line 

 'drawn through centers of eyes; margins of genae rounded; clypeus triangular, 

 tip broad and truncate, not extending below inferior margins of genae and con- 

 ■.tinuing the line of the genal margins, very strongly hirsute. 



Pronotum ovate, longer than broad, irregularly convex, mottled yellow 

 and brown, finely punctate, not pubescent ; head not at all visible from a 

 strictly dorsal view ; metopidium sloping, much broader than high ; humeral 

 angles very large, prominent, triangular, auricular, anterior half dark brown, 

 posterior half bright yellow, tips acute, extending outward and very slightly 

 upward; lateral margins of pronotum excavated just behind humeral angles 

 to expose bases of tegmina as seen from a dorsal view ; median carina promi- 

 nent, percurrent, brown ; posterior process bluntly rounded, tip obtuse, entirely 

 covering apices of tegmina.
