95. Diatrypa tuberculata Saussure? 



Diatrypa tuberculata Saussure, Miss. Mex., Orth. (1874), p. 479; Kirby, Syn. Cat. 

 Orth., II (1906), p. 93- 



Habitat. — A single male and four females of a Diatrypa from Chap- 

 ada and Corumba, Brazil, are referred to Saussure's tuberculata with 

 some doubt. They were taken during the months of March, April, 

 September and October, presumably by H. H. Smith. 



This species was originally described from Buenos Aires, Argentina. 



96. Diatrypa ornata Saussure. 



Diatrypa ornata Saussure, Miss. Mex., Ortli. (1874), p. 480; Kirby, Syn. Cat. 

 Orth.. II (1906), p. 93. 



Habitat. — I find a single female specimen belonging to the genus 

 Diatrypa, which agrees in most respects with Saussure's description of 

 D. ornata. Hence I am referring it to that species. The specimen 

 before me does not have the rufous tinge about the head and pro- 

 notum, but has them entirely deep steel-blue. It bears the label 

 "Along the Rio Guapore, below Rio San Miguel, Brazil, Aug. 22, 

 1909 (Haseman)." 



Genus Parcecanthus Saussure.

 Carsidava Walker, Cat. Derm. Salt. B. M., I (1869), p. 53. 



Parcecanthus is still another American genus of the family Podo- 

 scirtidae, which contains several described South American species. 

 These insects bear a rather striking resemblence to representatives of 

 both Diatrypa and Orocharis, but differ from them as shown in the 

 synoptic key printed on a preceding page. 



Only two specimens of this genus are represented among the collec- 

 tions now being studied. They are both males and represent quite 

 widely separated localities. The smaller of the two comes from Para, 

 Brazil, and mfght possibly be the Carsidava cinerascens Walker, which 

 Kirby {see Syn. Cat. Orth. II, p. 97) places in the present genus. It 

 also agrees fairly well with the description of P. vicinus Chopard 

 (Ann. Soc. Ent. France, LXXXI, pp. 420-421, 3 figs.) both in size 

 and color. Since it lacks the anterior tibiae it is unsafe to definitely 

 locate it with the latter, and Walker's description is too incomplete
