346 THE KNTOIMOLOOIST. 



No mention should be made of the Hemiptera were this 

 an attempt at a representative list, though one or two exclu- 

 sively marsh things, such as Cymus glandicolor at Wroxham 

 and Eockiand, Acompus rnfijies at the former, and Plociomerus 

 fracticollis at the latter, did happen to fall to our lot ; for the 

 rest, Nf/sius thynii occurred at Eaton, Psallus varians near Attle- 

 borougii, and a curious little beast that Mr. E. A. Butler thinks 

 must be the developed form of Plagioiinathus saltitans on the Win- 

 terton sand-hills. The common BijtJtoscopusflavicollis was beaten 

 from bushes at Hickling, with Euptcryx atropunctata at Horning. 



The Neuroptera were yet more disappointing, for more was 

 expected of them than Ischnura elegans, which literally swarmed 

 everywhere, and of which both the female forms were taken ; 

 Colpotaidiiis incisus and Chrysopa perla were also found. The 

 only uncommon Trichopteron was Limnophilas liirsutus, which 

 was not rare, with L. siKirsas on alder trunks at Eockiand. 

 Cloeon dipterum flew on to my coat, and was easily boxed without 

 dismounting at Acle Bridge, while Orthetrum cancellatum was 

 swept up at dusk in the Hoveton Marshes. 



With a genial atmosphere the result would doubtless have 

 been more congenial, and the real less unlike the ideal to which 

 we, in our innocence of previous experience, had aspired ; never- 

 theless the game was doubtless worth the candle, the length of 

 which becomes considerable at Broadland hostelries !

UNDESCEIBED INDIAN EHYNCHOTA : PENTATOMID^. 

 By W. L. Distant. 



BoNAciALUs, gen. nov. 



Body elongate ; head large, longer than broad, somewhat broadly 

 rounded in front, distinctly depressed before apex, the lateral margins 

 a little ampliated and recurved, the lateral lobes longer than the 

 central lobe and meeting beyond it, but a little cleft at their apices, 

 the autenniferous tubercles remote from the lateral margins, and dis- 

 tinctly inside the longitude of tbe eyes ; antennae five-jointed, first 

 joint short, incrassated, second joint not reaching apex of head, third 

 shortest ; rostrum reaching the posterior coxae ; eyes touching the 

 anterior angles of the pronotum ; pronotum broader than long, lateral 

 margins a little sinuate, lateral angles rounded ; scutellum more than 

 half tbe length of abdomen, narrowed towards apex ; corium with the 

 lateral margins almost perpendicular. 



Tbis genus, by the position of the antenniferous tubercles, 

 must be placed in the division Dymantaria of the subfam. Pen- 

 tatominse, a division only hitherto considered as containing 

 Australian and Ethiopian genera.
