go rilarch, 



sup. Bubcylindrical ; 2Tid joint, a strong curved acuminate claw, tapering evenly 

 from base to point, and rather longer than the 1st. Liable to be mistaken in the 

 net for Ph. humeralis, S ■ Subgenital $ plate truncate triangular, and roundly 

 eraarginate. 



Sab. : Miry places in the country surrounding Seaton, Devon. 



The remaining members of the old genus differ from the above in having the 

 (? app. inf. slender, subulate, slightly incurved, longer than their basis, enlarged 

 close to their articulation and unitenaculate with the tenacular spine cuneate or 

 spathulate and short. 



LoGiMA, f/en. nov. 



Bristling hair wanting on the posterior branch of the forked sector ; present 

 on the other branch, on the simple sector, tlie radius, the anterior cubitus, and the 

 Ist and 3rd anal viens : its endings on the radius, the anterior branch of the forked 

 sector, and on those two anal veins, approximated to the wing-margin, but those on 

 the simple sector and the anterior cubitus remote from the mai'gin and standing, 

 with the next tuft on each side of them, abreast of the end of the 2nd anal vein. 

 Joints 1 to 3 of the palpi subequal to one another, and rather shorter than the 4th 

 joint. Basal joint of S app. sup. curved and comparatively slender ; 2nd joint 

 shorter, slightly dilated near the base and falcate. Subgenital plate of ? very small, 

 transverse, and roundly emarginate with obtuse points ; blades of the ovipositor 

 short, subtriangular and acute. 



Type, L. erminea, Etn. 



PsYCHODA, after the foregoing have been separated from it, resembles Threticus 

 in the distribution of bristling hair on corresponding wing veins, and Logima in the 

 general form of the S app. inf. Of the published species, Ps. phalwnoides, L., and 

 alternata, Say {sexpu7ictata. Curt.), have antennae 15-jointed in the (J, but differ 

 from each other in the form of the penis, and app. sup. S (for the last. cf. Ent. Mo. 

 Mag., 2nd ser., vol. v, pi. iv, Ps. 2a and 4a), and the shape of the $ subgenital 

 plate, — subquadrate and emarginate, with the further corners rounded off in 

 phalsBnoides ; obovate-cuneate, and bifid in alternata. Describing this last species 

 in op. cii., June, 1898, p. 124, without microscopic preparations in Canada Balsam 

 for reference, I reckoned the diminutive loth joint of the antenna as an apiculus of 

 the 14th joint, and therefore described them as " usually l4-jointed." 



Psychoda albipennis, Zett., however, has only 14 joints in the i^ antennae, the 

 last diminutive. 



Telmatoscopus, ge7i. nov. 



Antennffi of the <? fly 16-jointed, nodose, with joints of full size at their tips : 

 flagellum furniohcd with 14 sets of verticillate hair inserted upon the nodes, the 

 Terticils mostly cupuliform or bowl-shaped, and imbricate ; several of the nodes, 

 towards the base of the series, oblate or napiform, and gibbous or extended laterally 

 into a rounded lobe, so as to render the thread or beak of the joint excentric instead 

 of innate. App. inf., (J , viewed from beneath, comparatively short and rather 

 straight ; their tenaculae mostly short and setaceous : app. sup. with a strong curved 

 subulate or claw-like terminal joint, usually much longer than the other joint. 

 Subgenital plate of ? emarginate, with rounded points, or excised with acute points 

 or fish-tailed with equal points and a curved or angular excision. The species can
