also from Neoeurys, with which it agrees in coloration. 

 And Neoeurys is also a smaller and much more slender 

 form, with evidently more elongate joints in its antennae, 

 and also in its legs — the hind tarsi (in particular) being 

 far longer in proportion to the tibiae. 



The four forms actually known to me which I should 

 unhesitatingly refer to Eurys may be tabulated as follows — ■ 



??• 



1. Abdomen entirely metallic', without yellow or whitish markings 



at the sides or beneath 2. 



— Abdomen with the inflexed sides of its dorsal plates margined 



at their posterior corners with white or yellow .... 3. 



2. Head, thorax, and abdomen metallic green or greenish-blue 



throughout, with slight golden, fiery, or cupreous reflections 

 in certain lights. Femora not blackened at their bases 

 above but entirely testaceous orange, concolorous with the.* 

 tibiae and tarsi. Length about 7 mm. . . laetus, Westw. 



Type (described as a " Dictynna ") at Oxford. 



— Head and thorax reddish-cupreous throughout, densely punc- 



tured and therefore somewhat opaque; the abdomen is dis- 

 tinctly greener, with little if any cupreous tint. Femora 

 evidently infuscated at their bases above. Rather smaller 

 than laetus — about 6 mm. long. 



rutilans, n. sp. ( = aeratus, W F Kirby! k«c Newman ?) 



W. F. Kirby called this specimen "aeratus, Newm.," 

 but it does not correspond at all well to Newman's descrip- 

 tion, which particularly states that the head and also the 

 thorax are " nigro-aeneous." Aeratus was described in 

 1841 from two specimens in the Collection of the Entomo- 

 logical Club. That Collection was presented a year later 

 to B.M., so the Types ought to be there now. But if 

 they ever arrived there, they have long disappeared, for 

 no mention of them is made in Kirby's List. (The present 

 specimen is certainly not one of the missing Types, having 

 been acquired at a much later date by purchase.) On 

 the whole I see no reason for identifying this form with 

 dentins. Newm., and provisionally treat it as distinct. 



Type in B.Al. 



.'J. The largest and most highly coloured of the forms. Length 

 about 8 mm. Head and thorax finely and rather closely
