153 OELECHIO/R. 



the continental species of tliis genus it tenninates above the a])cx) ; the 

 secondary cell is not indicated ; the subdorsal vein is furcate ; the sub- 

 median, posteriorly thickened, is remote from the median vein. 



The sj)ecies of this genus arc large, showy insects, and appear 

 to delight to fly in the sunshine. Only one occurs in tliis country, 

 and of that the larva is unknown. Of a continental species how- 

 ever, H.forficella, the larva has long been known as feeding in 

 decayed wood, hence probably our Engli^^h species has similar 

 habits.

Head yellow, with a dark fuscous blotch in the middle. Eace dark 

 fuscous. Palpi dark fuscous ; the last two-thirds of the terminal joint 

 Avhitish. Antcnufc yellowish-white, annulated with fuscous. Anterior 

 wings bright yellow, darker in the middle, and towards the apex suf- 

 fused with fuscous ; from the middle of the base is a straight leaden- 

 blue streak, which before the» middle of the wing is deflected, and ter- 

 minates on the inner margin about the middle, where it meets a nar- 

 rower leaden-blue streak from the base below the fold ; the costa at the 

 base is narrowly dark fuscous, and on the middle of the costa is a dark 

 fuscous blotch, in which arises a rather oblicpie leaden-blue streak, 

 running half across the wing ; beyond the middle of the inner margin 

 is a conspicuous triangular pale yellow spot, and a smaller pale yellow 

 triangular spot is on the costa rather posterior ; on the inner margin 

 of both of these spots are some Icaden-blue scales ; the veins in the api- 

 cnt portion of the ilhikj are indicated tnj black scales ; cilia dark fuscous, 

 the tips paler. Posterior wings dark fuscous, with paler cilia. 



Eroin the middle of May to the middle of .June, this beautiful 

 insect is generally a1)undant, in mixed hedges and in woods ; 

 the slow, undulating flight has some resemblance to that of an 

 Atleln ; it delights to fly in the early morning, preferring sumiy 

 morninu's.
