 simplicibus fere rectis. 



Individuum in mus. D. Hope vidi lineas 9^ tantum liabens, statu- 

 raque pariim minus robusta ; vix tamen species distincta.

 anticis rotundatis, lateribus in medio incisis angulisque posticis 

 acutis, elyti'is punctato-striatis, antennis sensim dilotatis.

Sj'n. Helops punctatus, Fabr., Syst. Eleuth. i. 161. 



Caput obscurum sub lente tenue punctatum ; clypeo pcjstice im-

 dratus angulis anticis rotundatis, lateribus in medio sinuatis, tenue

I give the insect here described as the true H. punctatus. Fab., on 

 the authority of a specimen received by the Rev. F. W. Hope from 

 Copenhagen, from AI. Westermann, who has such excellent oppor- 

 tunities of determining those Fabrician species which were described 

 from the cabinets of Lund and Sehestedt, as was the case with the 

 present species. Tliis is the more important, as the Fabrician de- 

 scription is so slight as to be applicable to scores of species of He- 

 teromerous insects. 



Nyctobates Hypocrita. Nyct. niger subobscurus tenuissime jmnc- 

 tatus, prothoracis lateribus subrotundatis integris angulis anticis 

 acutis, antennis lo7igioribus apice parum latioribus.
