Tiie ineso- and met.asterna are deeply fovcolate, the foveae varying much in 

 shape, and forming characteristic specific differences, and there is also sometimes in 

 the metasternum a median sulcus. 



The upper surface of the species is more or less setose, the setae being most 

 conspicuous on the costse, and in the thoracic punctures. 



The femora and tibiae are relatively short, and the tarsi and the antennae have 

 joints more equal in length and less lax than in Onthophilus. 



I give a list of the species in both genera, arranged systematically : —

AN ASIATIC PSYCEOPSIS {PS. BIRMANA, n. sp.). 

 BY ROBERT McLACHLAN, F.R.S., &c. 



The singular and beautiful Neuropterous genus Psi/cJiojJsis, Newm., 

 was long considered peculiarly Australian. Recently, however, Prof. 

 Brauer described a species from Kilimanjaro, East Africa, under the 

 name Ps. zebra (Ann. k. k. Naturhistor. Hofmuseums, iv, p. 102, 

 1889). I possess a species from Birmah, which is described below. 



PSYCHOPSIS BIRMANA, 71. sp. 



Body for the most part greyish-fuscous, M'ith grey hairs ; antennae (broken) 

 yellowish-grey in the basal portion. Head above blackish, with two large rounded 

 yellowish discal tubercles, and a similar small oval tubercle behind each eye, antennal 

 sockets yellowish ; eyes pale leaden-grey ; face and palpi pale yellowish. Pronotum 

 much narrowed in front. Legs pale yellowish ; femora clothed with long concolorous 

 hairs ; spurs of tibiae very short, testaceous ; claws short, testaceous, much curved. 

 Abdomen pale ochreous beneath, with dense whitish silky iiairs ; at the apex above 

 are two large subquadrate plates, separated at the end by a somewhat triangular ex- 

 cision ; beneath are two broadly triangular lateral plates (lying against the dorsal 

 plates), separated and open in front (viewed ventrally), the space between them 

 filled in with dense yellowish hairs ; in the middle of the posterior margin of the 

 penultimate ventral segment is a broad triangular excision, in which is a deep 

 blackish fovea. 



Wings very pale greyish, subhyaline, with faint darker greyish tessellation, and 

 vague indications of two or three faint transverse fasciae ; some slightly darker spots 

 in the space between the subcosta and sector, which space is slightly dilated towards 

 the end, and four or five more conspicuous darker spots along the cubital region 

 towards the inner margin ; fringes and pubescence whitish ; costal area very abruptly 

 dilated at the base, the nervules furcate or bifurcate towards the costa (occasionally
