e following features. From capitatus (De Geer) in the slightly 

 ^ore compressed form, narrower and deeper fastigium, less in- 

 flated face and genae, in the eyes having their outline more trun- 

 cate cephalad and less evenly circular, in the shorter pronotal disk, 

 in the proportionately longer and more shallow lateral lobes of 

 the pronotum, in the very elongate tegmina and wings, the much 

 more slender caudal femora and in the more sharply angulate- 

 emarginate subgenital plate of the female. From clausus 

 (Scudder) the new species differs in the more robust form, in the 

 shorter and broader face and mouth-parts, in the non-ascendent 

 fastigium, in the subtruncate caudal margin of the pronotal disk, 

 in the much longer and more shallow lateral lobes of the pronotum 

 (these being distinctly deeper than long in clausus), in the finer 

 tegminal texture, in the longer and more slender femora, the 

 longer ovipositor and the deeply (instead of extremely weakly) 

 angulate-emarginate female subgenital plate. 



Type. — 9 ; Porto Alegre, State of Rio Grande do Sul, Brazil. 



June, 1912. [Acad. Nat. Sci. Phila., Type no. 5324.] 



Size large: form moderately robust (more slender than hiB. capildlna, more 

 robust than in clausus), elongate: surface of head and pronotum more or less 

 finel.y punctate; tegmina closely punctato-reticulate proximad, becoming ir- 

 regularl}- reticulate distad. Head with its exposed dorsal surface equal to twice 

 the length of the dorsum of the pronotum ; face distinctly retreating from dorsal 

 surface of the fastigium to clypeal suture, three-fourths as long as the dorsum of 

 the pronotum: fastigium broad, its greatest width slightly more than the great- 

 est dimension of the eye, its greatest length hardly more than one-half its 

 greatest width-, distinctly but not greatly narrowed proximad, the cephalic 

 outhne, when seen from the dorsum, being arcuate obtuse-angulate; when seen 

 from the side the fastigium is not elevated dorsad of the general line of the head; 

 cephalic face of the fastigium slightly more acute than a right angle ventrad, 

 the tip well in contact and iml)edded in the fastigium of the fac-e: eyes little 

 prominent in basal outline, broad ovoid, the cephalic section of the outline 

 appreciably oblique and flattened: antennae broken. Pronotum rotundato- 

 deplanate dorsad, the greatest caudal width of the dorsum equal to two-thirds 

 that of the greatest length of the same: cephalic margin of the disk faintly 

 sinuato-truncate; caudal margin of same truncate, rounding laterad to the 



has some resemblance to the species here described, but the features of the 

 eyes, the presence of dark pronotal bars and the general curve of ovipositor 

 (although this is exaggerated in the figure) convince us he had capitalus before 

 him, his name accordingly falling in the synon\'my under DeGeer's species. 

 The color shade described and painted ))}' Stoll i.s, also, very different from that 

 found in the two individuals of lanista.
