NOTES ON BRITISH ORTHOPTERA. 173 



surface of the water, propelling themselves by means of their 

 hind legs. The passing of a cloud over the sun seemed sufficient 

 to prevent them taking to the wing. If a particular example was 

 followed, its flights appeared to become less and less strong, as 

 is perhaps the case with other grasshoppers. Specimens varied 

 greatly in colour and conspicuousness, one of a greenish tint 

 having a very pretty appearance. A fairly constant form has a 

 pale pronotum, which, being interrupted by the two triangular 

 dark spots near the base of the wings, causes the dorsal surface 

 of the insect to assume a dagger-like appearance. It may there- 

 fore appropriately receive the varietal name of stylifer. Of the 

 specimens of T. sabulatus put into the laurel-bottle thirteen 

 were females and six males ; but the females are much more 

 conspicuous than the males. Tetrix hipunctatus, Linn., was first 

 seen on March 23rd, when imagines were about at Prince's 

 Coverts, near Clavgate, Surrey. Three specimens were captured, 

 ail females. On April 24th five were collected in the neighbour- 

 hood of Aldridge Hill, New Forest — four females and one male, 

 all being mature. On April 27th this species was infrequent at 

 Marlborough Deeps. It was common on May 19th at one spot 

 on the southern slope of Boxhill, Surrey. On June 15th one was 

 taken mature near Horsley (W. J. Ashdown). One small male 

 and two females were captured near Dorking on October 24th 

 (T. A. Chapman). 



One male example of Gomphocerus riifus, Linn., was taken 

 near Dorking on October 24th (Chapman). On August 5th 

 Gotnphocerus maculatus, Thunb., was captured at Arthog in 

 Merionethshire (E. B. Nevinson). A dead female of this species 

 was found on August 19th in the New Forest, holding on to 

 grass-blades, as in life.* It was somewhat distended, but there 

 was no apparent cause of death. It fell to pieces at home in 

 the evening, so I presume it had not recently died. The last 

 specimens for the season noted were two females on Netley 

 Heath on October 26th (L. C. E. Balcomb). 



On July 28th a male imago of the fine bog-loving grasshopper 

 Mecostethus gwssm, Linn., was taken by Apsley " shade-pond," 

 near Oberwater in the New Forest. The next day a few imagines 

 were met with in the upper part of Duck Hole Bog : one captured 

 was a small male. On August 8th it was very plentiful at Denny 

 Bog, and six males and three females were taken casually as 

 I was looking for Utricularia iiiterniedia, Hayne. Large numbers 

 could easily have been secured. On eviscerating the females 

 one only was found to contain eggs — large and yellow, apparently 

 not yet ready for oviposition. At the upper part of Duck Hole 

 Bog I saw a number on August 9th, and took one male. On 

 August 30th a female was captured on Ober Heath, some quarter 

 of a mile I should say from the nearest bog, such as those on
