SOME NEW" SPECIES OF TRICEOPTERA BELONG-INa TO THE 

 EUROPEAN FAUNA, WITH NOTES ON OTHEES. 



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



The following descriptions, &c., and the figures that accompany 

 them, were mostly written and drawn some years ago, and formed 

 part of materials accumulated for a "Second Additional Supplement" 

 to my " Kevision and Synopsis ;" but having been compelled to 

 relinquish camera lucida drawing, the proposed second supplement 

 had to be abandoned. It is, however, advisable, for several reasons, 

 that the descriptions of the new species should appear, not the least of 

 which is that the types were returned to their owners with MS. names 

 attached : moreover, I recently saw one of the species here described 

 figuring in a trade catalogue under the name originally bestowed, but 

 not, until now, published. 



Reference is several times made to Albarda's collection. It is 

 well known that my esteemed correspondent, Mr. H. Albarda, was 

 compelled, owing to failing eyesight, to give up the study of entomo- 

 logy, and that he generously presented his collections to the Leyden 

 Museum, where they now are. 



LiMNOPHILUS PONTICUS {u. Sp.). 



Head and thorax above dull ochreous ; hairs yellow ; orbits of ocelli blackish ; 

 posterior warts very large, oval, transverse ; a fine median impressed longitudinal 

 line, which is sometimes blackish. Antennae brownish-testaceous, with paler annu- 

 lations. Palpi and legs yellowish, the latter with black spines ; coxse, femora, and 

 sides of thorax occasionally fuscescent. Abdomen fuscescent (greenish in life ?) ; 

 the margins of the segments (especially beneath), the lateral lines, and the terminal 

 segment, paler. Anterior-wings long and rather narrow, gradually dilated to the 

 apex, which is not very sharply truncate ; pale greyish, clothed (but not densely) 

 with pale golden pubescence mixed (microscopically) with blackish, without markings 

 of any kind, but there are sometimes indications (hardly visible) of paler irrorations ; 

 thyridium and arculus whitish transparent ; neuration fine, pale testaceous, with 

 sparse, short, blackish hairs, which become stronger and testaceous on the postcosta 

 and its basal branches ; no " beard " on the 1st apical sector in the S ; discoidal 

 cell longer than its footstalk, all the apical cellules broad at the base. Posterior- 

 wings hyaline, iridescent, pterostigmatic region slightly tinged with yellowish ; 

 neuration pale tescaceous ; discoidal cell shorter and broader than in the anterior, 

 much shorter than its footstalk ; upper branch of cubitus furcating on a level with 

 the commencement of the discoidal cell, or slightly after. 



In the S the last dorsal segment is rather thickly covered with small tubercles, 

 whence arise long pale hairs ; its margin is deeply excised if viewed in front, and on 

 either side is a large swollen projection densely covered with short black setae, 

 leaving the excision between them pale. Superior appendages concealed in the cavity 

 of the apex, broadly ear-shaped. Intermediate appendages likewise concealed, broad
