 II, pt. 1, p. 692. [Brazil.] 



Rio de Janeiro, State of Rio de Janeiro. November. (H .H. 

 Smith.) Two males. [U. S. N. M.] 



The present widely distributed species has been recorded from 

 this locality by Brunner and Bruner. 



Lobophyllus reversus new species. (Plate XI, figs. 32 and 33.) 



A striking species, differing chiefly from L. legurnen Saussure, from 

 "Brazil," the genotype and only previously known species, in the 

 more subequal dorsum of the pronotum, the much more ample teg- 

 mina, the distal portion of which is much wider, in the transverse 

 veins of the marginal field of the tegmina being directed proximad, 

 in the ramus of the median vein being proximad extremely close to 

 the median vein, in the more regular disposition and correlation of 

 the rami of the median and ulnar veins and in the caudal tibiae 

 slightly surpassing instead of being shorter than the femora. The 

 ovipositor of the new species is quite different from that of legumen, 

 being proportionately shorter and broader with a rotundato-trun- 

 cate apex and the margin of the same section denticulate. 



Type. — 9 ; Goyaz, State of Goyaz, Brazil. [Hebard Collection, 

 Type no. 473.] 



Size large: form moderately compressed: surface unpolished, teg- 

 mina and exposed portions of wings coriaceous, wdth a faint gloss. 

 Head with its greatest width slightly greater than the depth from 

 the occipital margin to the clypeal suture: occiput bullato-arcuate 

 transversely, regularly arcuato-declivent from the caudal portion 

 of the occiput to the fastigial suture: fastigium of the vertex very 

 broad, faintly broader than the greatest dimension of the eye, not 

 at all elevated above the general level of the head, broadly in con- 

 tact with the equally wide and similarly constructed fastigium of 

 the face, the inter-fastigial suture straight: surface of the fastigia 

 and vicinity cribroso-punctulate, the occiput and genae with scattered 

 indications of the same: eyes little prominent, relatively small, in 

 basal outline subcircular, with a slight flattening cephalad: antennae 

 not reaching to the apex of the abdomen, aside from the two prox- 

 imal joints very slender. 



Pronotum with the length of the disk about one and one-fourth 

 times the greatest width of the head, the greatest (caudal) width 

 of the disk contained one and one-fourth times in the length of 

 the same; disk nearly subequal in width; the lateral margins faintly 

 diverging, regularly, caudad, the cephalic width equal to about 

 nine-tenths the caudal width; cephalic margin of the disk arcuate-
