?. Upper-side pale grey-brown closely irrorated or marbled with lighter or 

 darker fuscous. Crown about one-half longer than the pronotum, 2-i limes as long 

 in the middle as at the sides. Last ventral segment aubequal in length to the two 

 preceding, its apex straight or feebly concave, with a small angular notch in the 

 1 1 1 i tl cl I e . Length 5— 5£ mm. 



Common ;it the roots of low plants in salt marshes, Hunstanton 

 .ami Wells, Norfolk. This is the insect which I formerly referred to 

 us a form of albifrons, L, but after further study in the field I am 

 convinced that it is sufficiently distinct to merit a separate name. 

 I have seen no really intergrade specimens between Umicola and 

 albifrons, and nothing could well be more distinct in appearance than 

 the prevalent form of each. In the males of Umicola there is a 

 tendency to the acquisition of white spots on the elytra, which in 

 extreme examples {forma maculata) form two narrow irregular 

 interrupted bands. This form is at first sight very similar to the 

 form of albifrons in which the normal broad white bands are reduced 

 to more or less disconnected spots •(? f. polystolus, Scott), but the 

 latter may readily be distinguished by its smaller size, broader and 

 less parallel-sided form, and the distinct convexity of the outline of 

 the pronotum and basal two-thirds of the crown when viewed from 

 the side.

 Continental writers agree in treating these as three distinct 

 species. 



DOUATURA IMPUDICA, Hor?. 



Tforvath's description applies to the insect which I formerly re- 

 garded as a large pale race of D. stj/lata,aud I therefore adopt his name 

 for it. D. impudica is easily distinguished from stylata by its superior 

 size (length, J 1 , 4 mm., ?, 5§ mm.) ; it occurs commonly in August 

 amongst grass on coast-sandhills at Holkham with Libumia boldi and 

 Demetrias monostif/ma ; I first found it on sandhills at Hunstanton in 

 July, 1885. 



Atutsanus yaiuegatus, Kbm. 

 A. schenkt, Kbm. 



plebeja, J. Sahib. 

 Whatever may ultimately be found to be the real affinities of 

 these two species, their habilus certainly accords better with Athysanus 

 than with Thamnotettix.
