184 ENTOMOLOGICAL TOUR. 



and Libellula Donovani taken : in the evening, Thyatira 

 Batis taken. 



19th. Wet morning: not out till after dinner: paid another 

 visit to Spitchwick and Buckland : captured Erastria fus- 

 cula, Electra jiopulata, rare ; a new Eupithecia, which we 

 have named nigro-punctata ^ Ptycliopodafumata, and Hypena 

 crassalis ; of the last species there were only three specimens 

 known, and they were all females, taken at Westerham, in 

 Kent, about thirty years since ; two by the late Mr. Plastead, 

 and the other by Mr. Haworth : we found both sexes, but the 

 males were considerably the rarest, and are much darker than 

 the female. 



20th. Dull morning : went again to Buckland : took more 

 Hypena crassalis; also Eudorea subfusca, and Chrysomela 

 varians, &c. 



21st. Again wet and dull : went to Holne Chace, the seat 

 of Sir Boucher Wray ; from thence to Spitchwick park, the 

 late residence of that eminent entomologist. Dr. Leach : re- 

 turned to Ashburton through Buckland ; Cychrus rostratus, 

 Argyrolepia tesserana and decimana, and a new Cnephasiay 

 also Quedius lateralis, rare, taken in Spitchwick park. Near 

 Buckland, we observed Thecla riibi in the greatest profusion, 

 hovering over a bank where a species of Thymus was in 

 bloom: the bank was sheltered from the wind, which was 

 blowing rather strong at the time : this, together with the at- 

 tractive scent of the thyme, was sufficient to account for their 

 congregating together in such prodigious numbers. 



22d. More wet with thunder : not out till after dinner ; 

 then started for Spitchwick, where we lodged that night at the 

 Tavistock Inn : the evening fair but windy. 



23d. Fine morning : walked across Dartmore Forest to 

 Tavistock, a distance of eighteen miles, over hills of an im- 

 mense altitude, composed of granite, sterile and uninviting; 

 not a tree or bush to be seen, excepting a few willows at Two 



a Eupithecia nigro-punctata, Chant. Alee Icete virentes strigd media tramversa 

 undulatd macularum nigrarum, intus quam anteriores maculas 6 aut 7 iiigras 

 habent. 



Alarum dilatio, 9 — 10 lin. 



Eup. V-ataesimillima at satis distincta, paullo major et striga numquam con- 

 tinua sed macularum nigrarum confecta. 



Habitat apud Spitchwick in Devon, imago diebus Junii baud infrequens.
