tam, non-raslrate corium, and the basal joint of the hind tarsi not black at the apex, 

 Meroglyphica is at once to be distinguished by the greater proportion of yellow in 

 the colour of the pronotum, owing to the narrowness of the black transverse lines ; 

 and there remain to be dealt with those specimens in which the black lines on the 

 pronotum are wider than tlie pale interstices ; of these latter we have certainly two 

 species. According to authentic specimens kindly lent to me by Mr. Douglas, these 

 two species are the luguhris and Stall of Douglas and Scott, and the essential differ- 

 ences between them are given in Brit. Hem., pp. 596, 597, but as these differences 

 are not there emphasized, I have thought it worth while to set them out in greater 

 detail below. Dr. Puton, who has examined Fieber's type of luguhrix, says that the 

 Stall of Fieber is not separable from that author's luguhris, and Mr. Douglas has 

 been good enough to lend me a male specimen, which is undoubtedly C luguhris, 

 but which Fieber himself labelled " C. Stall, Fieb., in K. K. zool. bot. Yerein." 

 Under these circumstances, and the name luguhris being the older, that of Stall falls ; 

 but as the Stall of Douglas and Scott is clearly not conspecific with luguhris, Fieb., 

 one has to determine what name it should bear. To this end I submitted male 

 examples of both our species to Dr. Puton, who says that the luguhris of Douglas 

 and Scott is the same as luguhris, Fieb., and that Stall, D. & S., is the same as 

 selecta, Fab. In the male of selecta, Fieb., there is a strong transverse keel on the 

 forehead at about one-third of the height of the inner margin of the eye (when 

 viewed from in front), bounded above by a rather deep impression ; the entire frons 

 below the keel is excavated, the excavation reaching from eye to eye. In the male of 

 luguhris, Fieb., there is a feeble transverse keel on the frons on a level witli the lower 

 margin of the eyes (when viewed from in front), bounded above by a large shallow 

 impression ; the excavation on the frons is feeble. The best character for separating 

 the females of these two species lies in the middle keel on the front of the pronotum, 

 which in selecta is nearly half as long as the pi'onotum, and in luguhris is not more 

 than one-fourth as long as the pronotum. C. luguhris and C. selecta occur together 

 in coast marshes in Norfolk, and I have always regarded them as being just as 

 characteristic of such localities as Qyrlnus elongatus or Salda pllosella ; but such is 

 not the experience of others, as Douglas and Scott give " Cambridge Fens " as the 

 locality for luguhris, and " brackish water in ditches at Gravesend " for Stall (selecta), 

 whilst Mr. Saunders says of luguhris (he did not know selecta at the date of his 

 Hem. Het. Brit. Islands) "common and generally distributed, often in brackish 

 water." Dr. Puton informs me that C. selecta has also been taken in Holland by 

 M. Fokker. 



Thamnotettix steiatulellus, n. s. 

 Yery similar to T. sirlatulus,¥al\. (indeed, the markings of the upper-side agree 

 with those of that species ad punctum), but apparently only half as large, with the 

 elytra subequal in length to the abdomen. Its actual length is 2^—21 mm., as 

 against 4 mm. for strlatulus. Appendages of the apex of the tedeagus (viewed from 

 above, fig. 1) two, lateral, gradually narrowing to their pointed apex, connivent about 

 their apical third, afterwards recurved. In strlatulus (fig. 4) the appendages of the 

 sedeagus (viewed from above) are four, of which the two outer are short and 

 spiniform, and the two inner are long, strap-shaped, pointed, bisinuate, and crossing 

 one another after the manner of the lines which form the figure 8.
