Demosis peltatus. 



(Plate II. fig. 5.) 



Parallelus, depressus, piceo-niger; thoracis limbo elytrisque flavis, 

 his apice nigris ; abdominis marginibus late flavis. Long. 3g lin. 



Hah. Lake N'Gami {Andersson). 



Nearly parallel, the elytra very little wider than the thorax. 

 Head and the basal joints of the antennse very slightly pitchy. 

 Thorax nearly one third broader than long, yellow, shining and 

 black in the middle ; the sides subparallel, reflexed, the posterior 

 angles very slightly prominent. Elytra very finely pubescent, 

 widest rather before the middle ; each elytron with four obtuse 

 costfe, the third abbreviated, the fourth continued over the shoulder, 

 the intervals rugulose and obscurely punctured, the apical third 

 black. 



At the time my account of the genera of Lycidce was written 

 (Trans. Eut. Soc, 1878) this species was considered to be the Lycus 

 scrobicollis of Fahraeus, and is the species referred to under 

 " Genus 4 " at p. 97. I have, however, since seen adifi"erent species 

 named L. scrobicollis, one which in some respects agrees better with 

 Flhraeus's description. It seems best therefore to consider the 

 insect from Lake N'Gami a new species. 



LIPERNES. 



Characters of Lycostomus, but with the palpi short and thick ; the 

 apical joint of the maxillary palpi nearly as broad as long, convex, 

 nearly straight on the outer side, rounded on the inner side. Thorax 

 with a mesial impressed line, the margins thickened and narrowly 

 reflexed. Each elytron with four costas, the fourth not elevated at 

 the shoulder. 



Lipernes perspectus. 



(Plate IL fig. 11.) 



Niger, nitidus ; thorace medio longitudinaliter impresso, margi- 

 nibus anguste reflexis, angulis posticis acutis ; elytris thorace paulo 

 latioribus, subparaUelis, testaceo-rufis, rugulosis, circa scutellum an- 

 guste nigro-cinctis. 5 . Long. 5-6| lin., lat. 2|-2| lin. 



Hah. Shanghai {Fortune). 



Eostrum short, about as long as broad ; apical joint of the max- 

 illary palpi very thick and ovate. Antennae moderately long and 

 slender. Thorax rather small, scarcely narrowed in front ; the 

 mesial longitudinal channel is wider in the middle. 



One example has the extreme margins of the thorax rusty red.
