64 COPEOGNATHA FEOM NORTHERN SARAWAK. 



Fore wing three tinies as long as wide, rounded at apical 

 margin. General colour hyaline, closely dotted with brown; 

 these dots confluent at some places of wing to larger spots and 

 thus forming an angulate cross band at the end of the basal 

 third of wing, then a spot at the basal half of pterostigma till 

 the branching of media from radial sector, finally a spot at the 

 distal half of areola postica till the branch of medial vein. 

 These spots (and the basal cross band) with very dark margins, 

 surrounded with hyaline, especially along both margins of cross 

 band, and a larger hyaline spot about in the middle of wings, 

 between the fore and hind marginal brown spots. The re- 

 mainder of wings closely dotted, especially in the apical part 

 and at extreme base of wing. Pterostigma very closely and 

 confluent ly dotted with brown in basal half, bright yellow in 

 the widened apical half ; there bluntly rounded at its hind 

 margin. Eadial sector united for some distance with medial 

 vein. Hind wings hyaline, dotted with brown at the fore 

 margin; venation as in P. kolbei. 



Length of body 3.5 mm. ; fore wings 5 mm. long, 1.7 mm. 

 wide. 



I have the pleasure of naming this new species after its 

 discoverer, the famous Swedish Entomologist, Dr. Erik 

 Mjoberg. 



One specimen from Mt. Murud, 6000—7000 feet, head- 

 quarters, collected in October by Dr. E. Mjoberg. 



This is the largest hitherto known species of the genus, 

 differing from the New Guinean P. kolbei, by the number of 

 hind tarsal ctenidia. The Philippine P. harkeri Banks and 

 the New Guinean P. loriai Ribaga — if they belong also to 

 the same genus which is not yet quite sure — are also smaller 

 than my Sarawak species and may be further distinguished by 

 a somewhat different coloration of fore wings. The Philippine 

 P. enderleini Banks seem to belong to Lichenomima — at 

 least so according to a specimen which I owe to the kindness 

 of Prof. Oh. F. Baker. 



Family PSOCIDAE. 



PSOCUS MURUDENSIS n. sp. 



General colour brown (balsam slide ex alcohol) ; legs some- 

 what paler, tarsi and the tips of tibiae dark brown. IVraxillary 

 palpi very dark, nearly black. Antennae beset with \ mm. 

 long, stiff, slightly curved bristle-hairs. The two short basal
