432 Mr. W. F. Kirbj — Notes on Phasmidaa 



considerably longer than broad, narrowed behind, with a 

 pair of short, stout, very obtuse horns on the vertex between 

 the eyes. Legs and body long, slender, smooth, legs nearly 

 straight; tibia3 carinated to the extremities, terminal spines 

 of the front femora and outer side of the middle femora 

 very slightly marked, those on the inner side of the middle 

 femora and on both sides of the hind femora more con- 

 spicuous ; first joint of tarsi at least as long as all the rest 

 together ; median segment fused with the metanotum, longer 

 than broad ; segments 2-7 of the abdomen from two to four 

 times longer than broad ; three terminal segments slightly 

 longer than broad, carinated above, terminating in a very 

 long operculum, trifid at the extremity. 



Appears to be allied to Clonistria, Stal, but with much 

 shorter antennae and very long operculum. 



Tersomia brasiliensis, sp. n. 



Female. — Light brown, legs pubescent ; meso- and meta- 

 notum above with a double yellowish line, head and pronotum 

 less distinctly streaked and dotted with yellowish.

Subfam. VI. Phryganisteiinm. 

 Lonchodidce, pt., et Bacterid*, pt., Brunner. 



I propose this subfamily to include the Eastern genera 

 Phryganistria, Sadyattes, and Pharnacia of St a I, and Tira- 

 choides of Brunner. The males are winged, except in 

 Phryganistria. Phryganistria is placed by Brunner in the 

 Lonchodidce, but its real affinities appear to be with the other 

 genera, which he places in his Bacteridse. They agree with 

 this group, as I have restricted it, in the form of the median 

 segment, and I think it best to treat them as an independent 

 subfamily.
