Two specimens (male and female) were found in a vial containing; Spi- 

 robolun surin((mrn8is, wliicih were identi«'al with a spe<'imeii in anotlier 

 vial from Paramaribo, Surinam. As these s])ecimens are from the same 

 region where the tyi)es o[' voarvtidus were from, I have not liesitate«l to 

 identify them with that species; in fact, if I had no males the locality 

 v»'ould be the princii)al means of identifying, as it is impossible to sepa- 

 rate /;ract7/«, coarctdfKs, and ilasi/x by any other point than that of the 

 male genitalia. My identifying these specimens with coarctatus and con- 

 sidering viearius and pocj/i identical, as shown by the co])ulation foot of 

 the males, has led me to study the «lit1'erent species belonging to this 

 group. Herelu'tbre (•oarctafus has been considered identical with Fon- 

 faria gracilift Koch, from Tulolos, Austria; but as i)roven by Latzel's 

 figure* of the copulation foot of Austrian specimens, this can not be. 

 Coarctatus ami (jracUis have also been considered identical with a 

 certain si)ecies from Borneo, Timor, Alinda and A'iti-Levu, and a few 

 other East Indian localities; but even these specimens as shown by 

 Karsch's figure t of the male copulation foot, although more allied to 

 gracilis than coarctntusj are not identical and represent an nndescribed 

 species (0. A'ar.sr/ii, sp. nov.). On account of these changes and dif- 

 ferences the species of Orthomorpha should stand as follows: 



1. Orthomorpha coarctata (Saussure) {^:^rkariuH\:^imeyi). Habitat: West lu- 



dies, Sminain, Brazil, and Africa. 



2. Orthomorpha beaumonti (Le Guillou) {^=r.npeciahHin Kars.h). Habitat: 



Horneo aud .Java. 



3. Orthomorpha pekinensia (Karsch). Habitat: Pekiii<r, China. 



4. Orthomorpha flavolimbata (Guldeusteeden aud Ej^eling). Habitat: Japan.

t P. ficarius Karsch may not be identical with coarviaiua, as his fignre of the male 

 genitalia only shows two i)oints, while in coarctatus there are three; but as they are 

 Ismail, it is very probable he did not observe the third.
