patch is considerably extended laterad along the caudal margin and 

 is sharply cut out on the sides. This form belongs to the same group 

 of species as minor, and to which apparently belongs hrasilianus 

 Saussure and sulzeri Guerin. 



We know nothing definite regarding the distribution of this species. 



Subfamily CORYDIX.E. 

 Melestora fulvella n. sp. 



Type: cf; Misiones, Argentina. December, 1910. (P. Jor- 

 gensen.) [Acad. Nat. Sci. Phila., type No. 5,212.] 



This species, the first of this very peculiar genus seen by us, differs 

 from adspersicollis and fuscella Stal, both from Rio Janeiro, in the 

 smaller size, non-lineate pronotum, and very much more uniform 

 coloration. 



Size small; form moderately depressed; body, except pronotum 

 and tegmina, covered with fine ochraceous pile. Head but very 

 slightly projecting beyond the pronotum, outline of the occiput 

 subtruncate; interspace between the eyes broad, about equal to one 

 and one-half times the greatest depth of the eye, this region and the 

 equally broad interantennal section impresso- 

 punctulate; eyes elongate pyro-reniform in 

 outline; antennae subequal to the body 

 in length. Pronotum transverse elliptical in 

 outline, the cephalic margin subtruncate, Fig. 3.—Meleslora ful- 

 lateral portions moderately declivent; surface ^f^^egnS (S^'ti^l 

 polished. Tegmina surpassing the apex of the ( x 4.) 

 abdomen by more than the length of the 



pronotum, very slightly inferior to the tips of the wings, sublanceolate 

 in outline ; costal margin gently arcuate, sutural margin straight in the 

 proximal two-thirds and thence arcuate to the rather broadly rounded 

 apex; venation of the peculiar type found in this genus, the trans- 

 verse veins forming regularly subquadrate or subrectangulate areas, 

 the surface of these areas as well as the costal field minutely papillose; 

 costal veins seven in number; anal vein joining the sutural margin 

 at about a third of the length from the base. Supra-anal plate with 

 the distal margin arcuate; subgenital plate asymmetrical; cerci 

 depressed, hardly tapering, apex moderately acute. 



General color rather pale ochraceous, on the disk of the pronotum 

 inclined toward tawny. Occiput ferruginous, passing into hazel on 

 the lower face; eyes clove brown; antennae drab.
