204 THE ENTOMOLOGIST. 



A NEW MYMAKID FROM NORTH WALES. 



By Lieut. -Col. Alfred W. Eyland, F.R.M.S. 



Neurotes flaviventris, sp. nov. 



<$ . Head, viewed from above, subdeplanate, almost twice as' 

 broad as long and slightly broader than thorax ; in side view globose 

 with a line of five or six stout hairs running from the vertex to frons ; 

 antennae filiform, of $ thirteen-jointed and longer than insect ; scape 

 dilate, sinuate, elongate and twice as long as first flagellum joint ; 

 pedicellus broad and compressed, sub-equal in length to first flagellum 

 joint ; first joint of flagellum half the length of the scape, the four 

 following joints equal in length and slightly longer than the first ; the 

 sixth to tenth equal in length and each slightly longer than the fifth ; 

 the apical joint slightly longer than the tenth joint. Thorax long, 

 one fifth longer than abdomen ; in side view elongate deplicate and 

 apically truncate. Abdomen subsessile. Legs slender and elongate, 

 and seated compact at base of thorax ; all tarsi longer than their 

 respective tibiae or femora ; all femora shorter than their respective 

 tibiae ; tarsi five-jointed. Wings narrow and elongate with the costal 

 margin convex and the lower margin straight ; pilosity infumate ; 

 cilia long, the longest nearly double the width of the broadest part of 

 the wing. Costal nervure strongly elongate, slightly more than half 

 length of wing, and slightly enlarged at tip. Hind wings narrow, 

 and more than two thirds as long as front wings, with long cilia. 



Head and thorax infuscate-fuliginous ; scape, pedicel, entire legs 

 and ventral side of abdomen flavous ; flagellum somewhat darker than 

 scape; dorsal area of abdomen nigrescent. A bdomen subsessile and, 

 in side view, subcuneiform, as deep as long and attached to thorax at 

 lower point of base. Tarsi of first legs longest, of hind legs shortest. 

 Tibiae of centre and hind legs of equal length ; femora of front and 

 centre legs of equal length. First and fifth joints of tarsi of front 

 legs of equal length and nearly double that of their respective 

 intermediate joints ; all second, third and fourth tarsi joints of equal 

 length except the third joints of the centre legs, which are slightly 

 shorter. 



Length, £ £ , -65 mm., -74 mm. 



At first sight this insect is much like Polynema, Hal., but 

 the abdomen is subsessile, the thorax longer, and the legs all 

 seated far back ; and it differs from Neurotes* iridescens, Enock, 

 in the entire pilosity of the front wings, which are more narrow 

 and elongate, with the apices more elongately ciliate. 



? . (Somewhat damaged.) Scape slightly shorter than that of £ 

 Antennae broken off above second flagellum joint; first joint one 

 third length of scape, second joint more than twice as long as first 

 Thorax somewhat stouter and not quite so apically truncate as in $ 



* This genus was described by Enock in the 'Hastings and E. Sussex Nat., 

 vol. ii, 1915, p. 178. The present insect is best placed therein for the present, 

 though the elongate alar cilia allies it more closely with Litus, Hal.— CM.
