TPIE ENTOMOLOGIST. 187 



upper wings asliy, tinged here and there with ochreous 

 shades; costa shghtly darker near the base; then a dark 

 costal streak-like mark near the middle, and another towards 

 the tip of the wing; between these two marks the costal area 

 is whitish : under wings ashy. Expands eight to ten lines. —

Correction of an Error : Food of Melissohlaptes bipunc- 

 tanus. — In my note on the habitat of this insect (Entom. iii. 

 154) I stated that the larva3 feed on the roots of Amraophila 

 arenaria. Mr. Doubleday most kindly informs me that the 

 larvae of every species of this genus feed upon the nests of 

 various bees : this accounts for their being found on one or 

 two plants among a number, and only on those that con- 

 tain a nest of a bee. They are never found in the same spot 

 the second year. The female must live through the winter, 

 as there are no bees' nests, at this late period of the year, in 

 which to deposit their eggs. — H. J. Harding ; 131, Lower 

 Sheet, Deal, October 10, 1866. 



Nepticula ceniifolieUa at Cheshunt. — Mr. Stainton re- 

 cords, in the Ent. Mo. Mag. for October, that he has found, 

 among some Nepliculae bred from the larva by Mr. W. C. 

 Boyd, of Cheshunt, several specimens of N. centifoliella. 



Prior Appearance of Male or Female. — Some time since 

 I said I would give the result of my experiments in this 

 matter. The residt is that I do not see that there is the least 

 ride in the whole thing. I dare say most Entomologists 

 knew this long ago. 1 find that a female of a batch of larvae 

 which went into pupa at the end of June is as likel}' as not 

 to emerge before a male of a batch that went down the end 

 of May, and vice versa. In some species the male emerged 

 first, in some the female ; in all there were about an equal 

 number of each sex. It seems to be a matter admitting of 

 little interest, and still less use. — [Rev) E. Halleit Todd. 



Prior Appearance of Male or Female. — Having noted the 

 time of ap])earance of the sexes of Plalypteryx unguicula, P. 

 hamula and P. falcula, 1 take the liberty of forwarding you 

 the result, if the subject of priority of a])pearance of male or 

 female is still of sufficient interest to find a place in the 

 ' Entomologist.' Platypteryx unguicula : of this species I 

 bred fifteen s])ecimens (eight males and seven females): the 

 sexes were so evenly represented that it is only necessary to
