iiotum shallowly, obtusely constricted just behind middle, provided 

 with a distinct ring-like collar. Scutellum much longer than wide, 

 carinate throughout, more obscurely so in front. Costal margin of 

 corium not at all concavely arcuated. Posterior margin of the meta- 

 pleura nearly straight. Incrassate fore femorse provided with two 

 or three subapical teeth intermixed with several smaller ones. Legs 

 longer than in Pcrigencs. Posterior tibix provided with long rigid 

 bristles. Posterior tarsus with the basal segment fully three times as 

 long as the second and third together.

Genus Ligyrocoris Stal. 

 I find m.yself obliged to retain this genus, although outside of the 

 ventral strigose vittK the characters are those of OrtJia-a Dall. for 

 inost of the contained species. But these finely strigose vittre seem 

 to me to be a sufficiently definite character to warrant us in keeping 

 this genus distinct. 



Ptochiomera (Carpilis) ferruginea Stal. 



The genus Carpilis was erected by Stal, 1874, from a brachypterus 

 male specimen from Texas to which he gave the specific name ferru- 

 ginea. Apparently the macropterous form was unknown to Stal and 

 is indeed very rare. The long-winged form is very different in ap- 

 pearance from the short-winged form, but an examination of it proves 

 beyond question that it is a true Ptochiomera. I have recently re- 

 ceived a macropterous female from Prof. H. M. Parshley. taken at 

 Orono, Me. In this specimen the head is imbedded to the eyes, the 

 pronotum anteriorly is without a ring-like collar and is transversely 

 constricted a short distance behind the middle ; the anterior lobe is 

 much narrower and twice as long as the posterior lobe. The clavus 

 is distinct, deflected to the corium and provided with three rows of 

 punctures. The membrane is fully developed and reaches to the apex 

 of the abdomen. The second joint of the antennre is twice as long 

 as the third. 



This seems to be a rare species. Mr. J. R. de la Torre-Bueno has 

 taken a J* and 5 (brachypt.) at Yaphank, L. L, Sept., 191 1. The 

 J* has the anterior tibia armed with a strong, sub-median tooth as in 

 Ptochiomera piibcrula Stal from Texas.
