340 THE ^ENTOMOLOGIST. 



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 Cyimis glandicolor at Wroxbam 

 and Eockiand, Acompus rufipes at the former, and Plociomcrus 

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

 rest, Nijsius thymi occurred at Eaton, Psallus variaiis near Attle- 

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

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

 tertou sand-hills. The common Bythoscopus flavicolUs was beaten 

 from bushes at Hickling, with Eupteryx atropunctata at Horning. 



The Neuroptera were yet more disappointing, for more was 

 expected of them than IscJnmra elegatis, which literally swarmed 

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

 ColpotauUus incisus and Chrysopa perla were also found. The 

 only uncommon Trichopteron was Lininophilus Jiirsiitus, which 

 was not rare, with L. sparsas on alder trunks at Rockland. 

 Clo'eon dipteram flew on to my coat, and was easily boxed without 

 dismounthig at Acle Bridge, while Orthetrum cancellatam 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 !

UNDESCRIBED INDIAN RHYNCHOTA : PENTATOMID/E. 

 By W. L. Distant. 



BoNAciALUs, gen. nov. 

 Body elongate ; head large, longer than broad, soinewbat 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 Uttle cleft at their apices, 

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

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

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

 shortest ; rostrum reaching the posterior coxa^ ; eyes touching the 

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

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

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

 lateral margins almost perpendicular. 



This genus, by the position of the antenniferous tubercles, 

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

 tatominae, a division only hitherto considered as containing 

 Australian and Ethiopian genera.
