312 On a new Genus 0/ Pytliidse. 



apices cleft ; mentum strongly transverse ; terminal joint of 

 the labial palpi oblong-ovate, narrow, that of the maxillary 

 pair short-ovate, ratlier stout, and obliquely truncate at the 

 tip ; antennae short, widening outwards ; protliorax short- 

 oval, obliquely compressed at the sides posteriorly, finely 

 margined at the base, immarginate laterally ; scutellum 

 transverse, subvertical ; elytra oval, striato-punctate, the 

 epipleura rapidly narrowed and about reaching the second 

 ventral suture ; prosternum well developed anteriorly ; ante- 

 rior coxse separated by a narrow lamella, the cavities open 

 behind and closed by the narrow sinuous ridge on the front 

 of the mesosternum ; metasternum short, the episterna 

 narrow ; ventral segments decreasing in length, 4 and 5 

 subequal ; tarsi pilose beneath, rather stout, the ante- 

 penultimate joint excavate to near the base above for the 

 reception of the small narrow penultimate joint, the terminal 

 joint and claws long; wings wanting. 

 Type, P. falkJandica. 



The single species from which the above characters are 

 taken has been found in numbers (dead) in seeds of tussac- 

 grass, Poa flahellata (^Dactylis ccef^pifosa), sent from the 

 Falkland Islands for the purpose of attempting to introduce 

 the plant into Scotland. 



It may be described as large, pallid, apterous Salpingus, 

 Gyll. {Sphceriestes, Steph.), with small, convex, laterally 

 projecting eyes, a short, broad, deeply inserted head, and 

 rather stout tarsi, with the ante-penultimate joint deeply 

 excavate above for the reception of the narrow penultimate 

 one. Two allied monotypic genera, Thalassogeton and 

 Chorimenum, from the Island of South Georgia'^, in the 

 S. Atlantic, have been recorded by Behrens (Stett. ent. Zeit. 

 1887, pp. 18-22, pi.). These S. Georgian insects have the 

 head more exserted than in the present genus, the eyes less 

 prominent, the tarsi simple, the antennae subfiliform, &c. 



Poophylax falklandica J sp. n. 



Oblong-oval, somewhat convex, shining, sordid testaceous, 

 the eyes and the tips of the mandibles black, almost glabrous. 

 Head sparsely, irregularly punctate, transversely depressed 

 on the vertex and with two large foveje in front ; antennae 

 rather stout, about reaching the liind angles of the protliorax, 

 joints 6-10 gradually becoming stouter, 9 and 10 about as 

 broad as long, 11 ovate. Protliorax rather convex, wider 

 than the head, broader than long, narrowed and constricted 



* Tussac-grass is also found on this island, according to Skottsberg.
