On a new Species of Chalinolobus. 289 



Notiolesthus morosus, Mots. 1873, is evidently K]/ct. rotundi- 

 coUis,yVestw. 1842; and raorosus will have to stand, on account 

 of the earlier rotundicollis. 



14. Nuptis and Augolesthus are at present unknown to me. 



Above I have proposed the generic name Taraxides for 

 Nyct. stnuatus, &c. This genus, with Derihs and AmenophiSy 

 is remarkable for the deeply excavated mososternum, the sides 

 of the excavation being angular in front. 



The three may be distinguished as follows : — 



A. Four posterior tibiae channelled nearly the whole 



length of their outer edge. 

 o. Antennae with the joints slightly serrate from the 



fifth joint Deriles. 



b. Antennae with the joints broader and strongly 



serrate from the fourth joint Amenophis. 



B. Four posterior tibiae cylindi'ical, not channelled . . Taraxides, n. g. 



From a note just received from Prof. Westwood respecting 

 some species oi Nyctohates described by him, it is clear that 

 N. hyjiocrita, moerens, and punctatus must be placed with 

 Taraxides^ and N. hiyens, Mots., will sink as a synonym of 

 moerenSj W. N. transversalis, Westw., will belong to Deriles. 

 N. hrevicornisj W., remains unknown to me : it " has the hind 

 tibife cylindrical, except at one third of distal end, which has 

 a slight impression gradually widening to the tip ; mesosternum 

 with the hind half convex, but with a groove on each side; 

 metastemum with a central impression, scarcely distinct in 

 front, but deeper in its hind part." It is evidently a Setenis. 



XXVII. — Description of a new Species of Chalinolobus from 

 Australia. By G. E. DoBSON, M.A., M.B., F.L.S., &c. 



Chalinolobus signifer^ sp. n. 



Ears and nostrils as in Chalinolohus tuberculatus ; but 

 behind the nostrils on the face, between and slightly in front 

 of the eyes, an erect transverse process (like the transverse 

 nose- leaf in Fhyllorhina, but smaller and not concave in 

 front) is placed. This process commences on each side at 

 a short distance fiom the eye ; and its free upper margin is 

 regularly convex. 



Wings from the base of the toes ; tail wholly contained 

 within the interfemoral membrane ; postcalcancal lobe well
