NOTES ON SOME SOUTH AMERICAN HALTICIDAE 



BY F. C. BOWDITCH 



The Monoplatid division of the "Oedipodes" originally mono- 

 graphed by Mr. Hamlet Clark in 1860 has received since then 

 comparatively scant attention. Von Harold and the late ]\Ir. 

 Jacoby have both described some forms and both commented on 

 Mr. Clark's paper and the difficulties of determining to which 

 section certain forms might belong. Other authors have added 

 a few scattered species. About half of Clark's and Harold's and 

 nearly all of Jacoby's species are represented in my collection. 

 Very many unnamed forms are present, the most striking of 

 which I have given names to in hopes of drawing attention to 

 this neglected tribe. Some of my species will later go into new 

 genera, but rather than increase the genera (where there is already 

 so much uncertainty) , I have considered it better to squeeze them 

 into existing groups until more specimens are at hand and further 

 study made. 



Mr. Jacoby ^ puts Hoinotyphus and Oinototus together under 

 the former name. It seems probable that Clark found difficulty 

 in his separation because in his work, page 124, he refers to H. 

 tuherculatus, meaning apparently 0. tuhercidatus, page 211, and on 

 page 212 he refers to O.fulginosus meaning H.ftdginosus, page 174; 

 a possible explanation being that after writing the paper referring 

 to the forms as above he shifted fulginosus from Oniototus to 

 Homotyphus and tuherculatus from Homotyphus to Omototus and 

 forgot to alter the text. At all events this supposition seems 

 reasonable and makes his references easily understood. 



Mr. Jacoby's three species of Omototus, i. e., quadri-plagiatus, 

 rubripennis and rufolimbatus differ in general facies entirely from 

 many of the species of Homotyphus and the same may be said of 

 my iridipennis and rosenhergii, especially the latter. Homoty- 

 phus (Omotyphus) carinatus Jacoby- should be changed to 

 jacobyi as the former name was previously used by Jaco])y for 

 a species from San Esteban.
