Although H. jiexuosus is included by Paykull, Gyllenhal, 

 Dejean and Sturm in the genus Hallomenus, it does not 

 agree exactly with the type, which has the apical joint of the 

 maxillary palpi subovate and truncated obliquely, the 3rd 

 joint of the antenna? longer than the following, and the inner 

 margin of the eye is distinctly notched. In their form they 

 agree,' being broader, flatter and shorter than Hypulus, to 

 which they are most nearly allied, and to the second division 

 of which H. Jiexuosus makes a near approach in structure. 



1. H. fuscus? Gi/ll. Ins. Suec. 2. 528. 2. — bipunctatus Payk. 

 var. /3. 



Length 2 to 2^ lines. Sericeous, thickly and minutely 

 punctured, brown above, ferruginous ochre beneath, 

 antennae palpi and legs ochreous, the latter bright and 

 pale; eyes reniform, black; head with a faint channel 

 on the crown : thorax with the sides ochreous, a shal- 

 low channel down the middle, and a distinct fovea on 

 each side at the base: scutellum subquadrate : elytra 

 w ith 7 or 8 indistinct impressed lines on each, the base 

 except at the suture, ochreous. 

 From the size I have some doubt if it be not a variety of 

 the H. humeralis Fab. ; but my specimens want the 2 black 

 spots on the thorax. 



This insect is common in Sw eden in the fungi of trees ; in 

 England no one but myself has ever taken it, and I have been 

 so fortunate as to capture two ; the first I took many years 

 since on the wing in the New Road, and the second flying in 

 Montague Square, a little before sunset, the end of May 1832. 



2. H. flexuosus FayJc. — Curl. Brit. E?il. pi. 474. — undatus 

 Pa7iz. 68. 23. 



For specimens of this pretty insect, which is quite a new 

 discovery in Britain, I am indebted to my friend Mr. C. J. 

 Thompson ; they were presented to him by Mr. Frederick 

 Kenrick, who took them the beginning of last July under the 

 bark of a dead Willow-tree, by the side of a river near Peter- 

 borough. It is found also in Sweden in the fungi of trees, 

 especially the Alder ; and Mons. Foudras kindly added spe- 

 cimens to my cabinet, which he captured near Lyons. 



The Plant is Sisymbrium sylvestre (Creeping Water-cress), 

 from the banks of the river near Bottisham, Cambridgeshire.
