2. Gorixa denseconscripta, Breddin. Novo Friburgo (coll. 

 Montandon). 



3. C. kollarii (Fieber). Guadelupe (coll. Montandon). 



4. C. hyalinipemiis (Fabricius). Sigara hyalinipemiis, Fabri- 

 cius, cannot (if the male example from Java in Dr. Montandon's 

 collection belong, as I believe, to this species) be referred to the 

 genus Cymatia, Douglas and Scott, and is therefore only remotely 

 allied to C. bonsdorjpli (C. E. Sahlberg) and G. coleoptrata 

 (Fabricius). It belongs to the genus Corixa, Geoffroy, and may 

 for the present be referred to the subgenus Agraptocorixa, Kirk- 

 aldy, although I have not been able to find a strigil in the male. 

 I have not erected a new subgenus for it, as I have seen only one 

 example, which may not after all really be referable to the species 

 of Fabricius. 



To the characters of Agraptocorixa (1898, Ann. Mus. Genov. 

 (2), xix. p. 144) should be added : — " Palae subcultrate, armed 

 with at least one row of denticles on the concave side. Strigil 

 present." C. hyalinipemiis has the frons (male) lightly im- 

 pressed, not at all excavated. 



5. Anisops na'ias, n. sp. 



? . Vertical margin (vertex) two and a half times as wide as 

 synthlipsis, lateral margins of notokephalon slightly-eurvedly diverging. 

 Scutellum one-fourth longer than pronotum. Pronotum obsoletely 

 punctured, scutellum smooth, elytra punctured. Anterior tibiae flat- 

 tened, much dilated laterally, curved outwards, as long as tarsi and 

 claws together ; first tarsal segment one-half longer than second, 

 which is twice as long as (each of) the stout digitiform claws. Tarsi 

 somewhat incrassate, the second segment stouter at the apex than at 

 the base. Intermediate tibia? similar to the anterior, one-fourth longer 

 than tarsi and claws together ; first tarsal segment one-half longer 

 than second, which is twice as long as the falciform claws. Length 

 7 mill., width 1-7 mill. 



Chile, Vina del Mar (Perth Museum and my collection). 



Luteo-stramineous. Abdomen blackish. Claws tipped with black. 



Very different from any other American species. Allied, 

 though much slenderer, to A. wakefieldi, F. B. W. White, from 

 New Zealand. 



The two individuals bore the manuscript label " Notonecta 

 hyalinipemiis. " 



Acanthia reuteriella, n. sp. 



Belongs to typical subgenus, and would be included in section 

 " ee " in Stal's catalogue of exotic species. 



Superficially punctured. Rostrum reaching beyond intermediate 

 coxae to base of mesosternum. Third and fourth segments of antennae 

 pilose, with long sparse bristly hairs also ; fourth segment a little 

 swollen. Second segment twice as long as the first, one -half longer 

 than the third ; third and fourth equal. Posterior tibias nearly three
