of placing this insect in any of his, or my, already characterized genera. 

 I, therefore, characterize it as follows : — apex of elytra very obscurely 

 sinuate ; elytra strongly margined at base ; suture between 2nd and 

 3rd segments of hind-body strongly defined, the apical three segments 

 with very deep sutures ; a systematic seta at base of pronotum on 

 either side. I do not observe any other striking structural distinction 

 from Blackhurnia, but the species {friqida, mihi) is, as a species, very 

 different from the know^n species of BlncJcburnia. I have given this 

 genus a name from the Hawaiian language, referring to its connection 

 with a lofty mountain.

Nematus Fletcheei, sp. n. 

 Black ; antennse brownish beneath, as long as the thorax and abdomen, taperingi 

 towards the apex ; tegulae, apex of coxa?, trochanters, base and apex of four anterioMJ 

 femora, extreme base and apex of posterior, four anterior tibiae and tarsi, and posii 

 terior tibiae, except theapex, white. Wings hyaline, costa fuscous, stigma blackism 

 Claws with a sub-apical tooth. Length, 2^ — 2j lines. 



The J I have not bred, but a caught specimen from Thornhilj 

 seems to pertain to this species. It has the antennae as long as thci 

 body, the 3rd joint is a little compressed ; and they taper very peri 

 ceptibly towards the apex. 



The larva feeds on hawthorn, eating the leaves along the edge( 

 against which the body is closely pressed. It is light green, the ana:^ 

 segment red, head brownish. 



a. crafcegi, Zaddach (Schr. Ges. Konig., xxiv, p. 147), appears tdj 

 be very closely allied to this, but it would seem to differ in having thnj 

 labrum, mandibles, and the edge of the pronotum, w^hite ; the an 

 tennse red, except the two basal joints, which are black ; and the ape: 

 of the middle tarsi and the base of the posterior are reddish -yellow. . 



Bred by Mr. J. E. Fletcher from larvae collected at Worcester [ 

 I have also found it in Clydesdale. There is a third form foun( | 

 on hawthorn allied to iV. craicegi and Fletcheri, but I have not ye ' 

 made up my mind as to its specific distinctness.
