As this insect occurs together with //. (lijfinis soita, and is always distinguish-

As fuciformis is undoubtedly the correct name for the broad-bordered 

 Palaearctic species we do not see any objection against the employment of the uame 

 tifi/KS for the narrow-bordered one. Linne's description applies equally well to all 

 the clear-winged species ; the unpublished description referred to by Aurivillins, I.e., 

 fits the insect figured by Esper as bombyliformis. As Linne treated, in 17G7, tityas 

 as a variety of fuciformis, we may safely assume that he knew indeed both the 

 broad border and the narrow border, but was not convinced (if their specific 

 distinctness. 



The name of boinbylifunnis, ajiplied by Esper and others to the jjresent species, 

 and misapplied by Illiger and most Continental Lepidoptcrists to fuciformis, cannot 

 stand for the narrow border, for the character '■'■ (ili<lomin.e coccineo," and the fact 

 tiiat Linne treated bombi/liformis in 1707 as a variety of porcellus, speak decidedly 

 against the type of bombi/liformis having been the narrow border, while the 

 character ^' ana barbato " does not fit porcellus ; " alts kyalinis lutco raiiis" might 

 apply to a fresh specimen of Uacmorrhnjia that has not lost the scales, but also to 

 a strongly rubbed porcdlus. 



The names tityns for the narrow linrdcr, and 7 «r//o;7«/iS fur the broad border, 

 are easily remembered if we keep in mind X\\&i, fuciformis fc. ding on Galium, and 

 fityu.-i on Srabio.sa, the initials of the insect and these food-jdants are neighbours in 

 the aljiliabet, and I'urther, that fi/i/u.i is tcnu>ter maryinatus (has a thin border), and 

 ih&X, fuciformis is '■' fortitcr" mnn/iixttus.
