ever, are liable to abrasion. The same remark applies to " Pedes albido-squamulosi." 

 Scbonherr's type may, as Mr. Crotch remarks, have been in particularly good 

 condition. 



5. " Femoribus... omnibus suhtiis dente ohhiso armatis." 



This character, as regards the anterior femora, T have failed in detecting. They 

 seem to want the tooth. 



I must leave the final decision of the matter in the hands of better judges. 

 But, with these discrepancies between the actual specimens and Gyllenhal's 

 description, I hope the hesitation I have expressed as to the insertion of the insect 

 as " suturellus," Sch., in om- lists will be pardoned in a tyro by those who are masters 

 in the science. 



It is not at all unlikely that other cabinets contain examples of the insect 

 mixed up with cyanipennis. I subjoin, therefore, a few marks whereby to dis- 

 tinguish the new species. 



Rostrum in ? longer than in cyanipennis : nearly glabrous, except at the base, 

 where the punctures are very fine : in S the rostrum is shorter, and punctured 

 very nearly as in cyanipennis. 



Head : not quite similar to cyanipennis, which has a depression between the 

 eyes. In this insect the forehead is either round ( ^J ), or has a quasi furrow, roughly 

 and indistinctly marked. 



Thorax entirely destitute of setae, which are obvious in cyanipennis ; this latter 

 also has the thorax distinctly wider at the base. The anterior margin in the new 

 insect is unreflexed in ? , and only slightly so in S . 



Elytra : Narrower at the shoulders, and distinctly more rounded than in cyani- 

 pennis : setse wanting, or nearly so : interstices rounder, and clothed with delicate 

 short hairs, regularly distributed : in cyanipennis the hairs are longer and less 

 regular. The whole contour of the elytra is more convex than in cyanipennis, and 

 the colour brighter ; the thorax being concolorous. — W. Tylden, Stanford, near 

 Hythe. 



[To the above-mentioned points of discrepancy between the so-oalled " sutu- 

 relive" and Gyllenhal's description (his insect being, moreover, from Tauria) I may- 

 add that in my two specimens (given to me by Mr. Tylden ; and one of which is, 

 if anything, rather larger than the usual run of cyanipennis) the apical margin of 

 the thorax beneath exhibits no trace of red colour, whereas it should be rufescent ; 

 and the strias of the elytra are strongly and evidently — instead of " obsolete" — 

 punctate. As regards the scales, any idea of abrasion is negatived by the exceed- 

 ingly bright appearance of the scapular patches. 



In endeavouring long ago to identify this insect with any of the species 

 described in Schonherr's work, I remarked (as did Mr. Tylden, separately) that 

 there are three or four allied to cyanipennis therein, the descriptions of which so 

 nearly resemble each other, that, if it were to be forced to that of sutwelliis, no 

 confidence could be placed in any of them ; for there are certain particulars wherein 

 some of those alUed insects come nearer to our species than the descriptions of the 

 corresponding parts of suturellus. Gyllenhal, moreover, in describing these insects , 

 draws the finest distinctions both of colour and structure ; siich as particularizing
