m-cu and the apices of aa and a3 white, by the colour-pattern of the upperside. 

 Upper fore-parts sordid ivory-white. Crown about one-third longer than half 

 its basal width, a little shorter than the pronotum, tree sides gently arcuate. 

 Inter-ocellar line broken into four spots, of which the two inner are the larger; 

 inter-ocular line represented by two large black triangles on the disc which 

 encroach more or less on the basal markings. Pronotum with several large 

 irregular markings behind each eye, a pair of stripes down the middle, and 

 sometimes a stripe on each side of the hinder half, black. Scutellum with a 

 black niidiUe-stripe from the base to the groove. Elytra as long as the abdo- 

 men with cell 3rd M longer than wide, or leaving the two apical segments 

 uncovered and having cell Jird M wider than long ; irregularly speckled with 

 black, the speckling, instead of being more or less evenly distributed as in 

 A. I'll i-ici/(tt lis and A. scheiiki, congregated on the clavus and the disc of the 

 coriuui 80 as to suggest two wide indeterminate stripes on each elytron. 

 Female genital valve similar to that of A. plebejus, twice as long as the 

 preceding segment, its distal edge simple. Length 5*5 mm. 



Dai-tford Heath, September 20th, 1890 (Z). Sharp). 



Many years ago Dr. J. Sahlberg determined a specimen sent to him 

 by Douglas as distinguendus Kbm. without doubt ; but Scott preferred 

 to regard this insect as a form of A. obscurellus (lineolatus). 



Limotettix persimilis, n. sp. 



We have in our collections under the name of Limotettix 4<-notata 

 Fab. two species, in one of which the aedeagus has a very characteristic 

 large rounded lobe at the base, and in the other, for which I propose the 

 name given above, this lobe is entirely wanting. L. persi?nilis frequents 

 drier })laces than those inhabited by X. 4-notata, and it is further distin- 

 guished by the feeble developement of black pigment on the upperside 

 and legs. In L. 4i-notata some of the cells of the elytra, especially those 

 of the clavus, are marked with fuscous to black, the apical cells are 

 fumose, there is a well-detined black line on the outer side of the front 

 tibiae, and a black stripe on the inner side of the hind tibiae. In 

 i. persimilis the elytra are not marked with fuscous nor are the apical 

 cells fumose, the black line on the outer side of the front tibiae is feeble 

 or wanting, and the black stripe on the hind tibiae wanting or only indi- 

 cated on the basal half. I found the tirst example of L. persimilis in 

 July 1915, in a grass field near my house, and put it aside as jiossibly 

 an example of what Giard called " castration parasitaire," although no 

 parasite was visible ; but in 1919 I got several similar males in the same 

 field. I'urther investigation showed that in all the so-called L. -h-notata 

 taken in other than wet situations in this district the males had no lobe 

 at the base of the aedeagus ; and this is also the case in a specimen from 

 Tintagel. Cornwall, sent to me by Mr. E. A. Butler in response to my
