OMALOTETTIX Bruner. 

 Omalotettix signatipes Bruner. 



Sao Paulo. September 1 to 14, 1900. (Hempel.) Nine 9 . 



These specimens are uniformly, though slightly, smaller than 

 Chapada, Brazil, and Sapucay, Paraguay, females, but in no other 

 respect do they appear to differ from topotypes. 



H0MAL0SAPARUS6 n. gen. 



A member of the Xiphiolce and related to Saparus Giglio-Tos and 

 Xiphiola Bolivar, differing from the former in the less compressed 

 general form, in the form of the frontal costa, the less produced head, 

 the less compressed pronotum, the more rounded tegmina, the more 

 robust limbs and the produced subgenital plate ; differing from Xiphiola 

 n the more compressed form, in the absence of distinct lateral angles 

 to the pronotum, the absence of any costal projection between the 

 antennae, in the broader tegmina, in the narrower interspace between the 

 mesosternal lobes and in the produced subgenital plate and slender cerci. 



Vertex ascending; fastigium rectangulate ; frontal costa not project- 

 ing between the antennae, becoming obsolete ventrad of the ocellus; 

 face declivent; eyes acute ovoid, hardly projecting; antennae heavy, 

 depressed, very slightly expanded proximad. Pronotum rugoso-punc- 

 tate; dorsal transverse sulci three in number; median carina distinct; 

 caudal angle of the disk subrectangulate; lateral angles without 

 carinas. Tegmina exceeding the apex of the abdomen, rather broad, 

 greatest width in the distal third ; intercalary vein absent. Prosternal 

 spine erect, slender, apex blunt; interspace between the mesosternal 

 lobes very distinctly longer than broad ; interspace between the meta- 

 sternal lobes very narrow. Subgenital plate of the male produced, 

 acuminate, keeled. Caudal femora moderately inflated; caudal tibiae 

 with nine spines on the lateral margins.

Homalosaparus canonicus n. sp. 



Type: 6"; Sao Paulo, Brazil. September 13, 1900. (Hempel.) 

 [A. N. S. Phila.] 



Size medium; form distinctly compressed ; surface ruguloso-punctate. 

 Head with the occiput regularly ascending to the interocular region 

 which, with the fastigium, is subhorizontal; interocular region slightly 

 more than twice the wddth of the interantennal portion of the frontal 

 costa; fastigium broadly trigonal, the apex with a short, distinct, 

 median, longitudinal sulcus; angle of the fastigium and vertex, when 

 seen from the lateral aspect, rounded rectangulate, the facial line being 



5 'OfiaTiOQ, resembling, and Saparus, a generic name.
