less obvious when seen from above than iu quimiuelineatns. Dorsum 

 in 5 (apparently) more \vhitish-s;re\' in ground-colour. AlxJomeyi : 

 Ist and 2nd segments yellowisb, latter wirli a rather broad black 

 band on liiud margin, enlarged triangularly in middle, where it 

 extends forward beyond centre of segment ; 3rd segment yellowish 

 with a similar black band (in some cases broader than that of 2nd 

 segment) and an irregularly shaped black spot on middle of 

 anterior margin ; 4th segment shiniiig black with a curved, dull 

 yellow, transverse band with parallel sides (sometimes in the shape 

 of a wide open inverted V) across centre of segment, its upper part 

 generally touching anterior margin of segment ; in some spec'nnens 

 this band is faintly present, though )iarro\ver, on 3rd segment also ; 

 extreme margins of 2nd and 3rd segments, and also the part of 

 4th segment j^osterior to the yellow cross-band, more shining than 

 the other black parts of the abdomen. In $ , the yellow parts on 

 2nd and Srd segments often more uniformly M'ide than in J ; the 

 yellowish-white band on 3rd and 4th segments straighter, and a 

 similar though smaller band on the 5th segment. Pubescence of 

 abdomen almost wholly pale yellow, but blackish-brown on black 

 parts of 2nd segment; in some specimens the pubescence of the 

 3rd segment is also a little brownish. Venter as in qtdnqtieUneatus. 

 Leys iriuch as in quinquelineatus, but anterior femora with more 

 black pubescence on upper, lower and inner sides ; all tarsi with 

 1st and 2nd joints wholly, 3rd basally, yellowish. Wings as in 

 quhu/uelineatus.

Though closely resembling quinqvelineatus, Y., tiie present 

 species is distinguished by the absence of dark stripes on the eyes. 

 The narrow, bare, shining black stripes on the face are much 

 reduced or absent, and the median facial stripe is also absent or 

 reduced to a trace only ; the thoracic dorsum is more yellowish 

 ( c? ) or whitish ( $ ), and the stripes blacker and very^ shining ; 

 there is more yellow iu the 2nd and 3i'd abdominal segments, and 

 the tarsi are more yellowish. 



E, quinqnevittatus, Macq., is probably synonymous with quinque- 

 striatus, ¥., as it is said to have tlie eyes spotted. No special 

 mention is made by Macquart of the colour of the hind tarsi : from 

 the coloured plate these appear to be dark, whicli might make 

 de Meijere's ohscuritarsls a synonym of Macquart's quinquevitfatus ; 

 but judging by the breadth of the abdomen the latter is probably 

 merely a synonym of the common E. quinquestriatns, Fabr. 

 Sip'pJuis megacejihalus, 'Rossi,is evidently synonymous with E. qtiin-
