Helsingfors muséum are from Arabia (Welledje Gebel Melham) 

 and are taken by Dr. Schweinfurth. The occurrence of this 

 species in Arabia is of interest but not surprising, as southern 

 Arabia lias a purely ethiopian fauna with intermingling of very few 

 palearctic and no Indian forms.

5. Porta DisT. — In 1903 Distant described from liie Malay 

 States a new genus and species under the name h'orta gracilis, 

 referring it to the family Coreidee, subfam. Alydinas. A glance at 

 Distant's figures (Fasc. Malay., Zool., I, pi. XV, fig. 6 and 6a) is 

 sufficient to show that this insect has nothing to do with the 

 Goreidse;, and the examiuation of a cotype proved it to belong to the 

 family Myodochida» (Lygaeid^e), subfam. Myodochime, div. Myodo- 

 charia, where its place is not far from the typical genus Myodocha 

 Latr. The referring of this genus to the Coreidas-Alydina; is simply 

 absurd, and would be impossible to account for in the writings of 

 any other hemipterist, but it is quite in keeping with the same 

 author's placing af Corizus in the Myodochida?. The original 

 description contains so little by which the genus could be reco- 

 gnized (not even the spinous fore femora being mentioned) that it 

 is necessary to redescribe it.
