mollicula, Boh., respectively, I am enabled to make the above correction, 

 The types bear out the respective descriptions in all points, except the \ 

 comparative lengths of crown and pronotum, which, on actual measure- 

 ment under the microscope, are as follows : citrinella, ^ , 2 4<, ? , 

 2—5; mollicula, c^, 3— 6, ? , 2— 4 ; the pronotum, therefore, proving, 

 in each case, to be at least twice as long as the crown. Seeing that 

 the structure of the ^ genitalia is identical in both the above forms, 

 the comparative differences in the length of the 2nd and 3rd apical 

 areas can scarcely be allowed to confer specific rank, the more 

 especially when we examine specimens intermediate in this respect, 

 but identical in the c? genitalia, of which latter I possess several.

5. PTGMJEA, Dougl. 



S . Orange-yellow ; abdomen above black, genitalia yellow. Corium and clavus 

 inwardly paler orange than on their outer sides, nerves deeper orange, inner margin 

 of clavus with a fuscous line. Membrane with a slightly fuscous tinge, nerves pale 

 orange. Legs orange ; claws infuscated. Length, 2^ mm. ^y 



Darenth Wood, October. 



The single ^ on which this species was founded still remains 

 unique. 



6. TARIATA, Hardy, = aridellus, J. ^ah\h.,= cephalotes, ¥ieb. 



Pale greenish-yellow, dull ; abdomen black. The colour of the elytra varies 

 to dark green, sometimes with a reddish tinge, or occasionally deep orange-red, the 

 latter in Northern examples. Length, 3k mm. 



Damp places ; common, but local. 



7. AUREOLA, Fall. 



Crown, pronotum, and scutellum yellow, elytra light yellowish-green ; abdomen 

 above black. Fore-parts and legs, particularly the face and the latter, frequently 

 tinged with red. Easily distinguished from the last, the only British species with 

 which it can be confounded, by its entirely opaque elytra. Length, 2J— 2t mm. 



On Carices, Findhorn Marsh, Forres, Morayshire. Said to occurfflie 

 on Calluna in August and September. 



Typhloctba salicicola, n. sp. 

 Somewhat larger and decidedly stouter than T. roscB. Very pale creamy- white, 

 scutellum tinged with pink, at least, in fresh examples. Penis surmounted by a tuft 

 of four long siokle-shaped appendages. Length, 3^—41; mm. 



On sallows ; common. 



I have long been of opinion that our pale sallow-frequenting 

 TypUocyha was distinct from rosce, but I have only recently had an 

 opportunity of confirming that opinion by a critical examination of! 

 the ^ genitalia.
