il-1 INSECTA MADEREXSIA. 



olus in coloiu", being of a bluisk or chalybeous tint. The obscure brassy-green 

 hue which is so perceptible on the elytra of the normal specimens is precisely 

 sunilar to what we observe in that insect, — a remark which Avill equally apply to 

 tlie (rather considerable) cui"vatui'e of its rostrum. I am informed Ijy M. Bohe- 

 mann that it agrees with the A. ch((lybeipenne of Schonherr {in lift.), and I have 

 therefore retained it under that name. It seems to he confined to intermediate 

 and rather lofty elevations, occurring amongst herbage during the spring and 

 summer months. I have taken it towards the head of the Kibeiro de Santa. 

 Luzia in May ; from off a species of Mallow at the Feijaa dc C6rte in July ; and 

 on the ascent of the Pico E,uivo from the Curral das Freu-as early in August : 

 and I likewise captured it on the grassy mountain- slopes of Porto Santo (imme- 

 diately below the summit of the Pico de Facho) during April of 1848. The vai\ (5. 

 I have hitherto only detected at the Feij{\a de C6rte.

A. viridescenti-seneum nitidum, pai'ce et subtiliter einereo-pubeseens, rostro elongato gracili, pro- 

 thorace parvo profuiidc ct rugose puuctato, clytris ovatis crcnato-striatis et magis metallicis 

 (plerumquc plus minusvc cuprescenti-micantibus), interstitiis minutissime rugulosis et punc- 

 tulatis, antennis pedibusque longiusculis robustis fere nigris.

Apion Wollastoni, Chevrolat, in Cruer. liev. de Zool. iv. (2''">« serie) 278 (1852) . 



Habitat in Mader^ boreali, ad Sanctam Annam super plantas Equiseti ftuviatilis sestate a.d. 1850 a 

 meipso sat copiose repertum. 



A. grceuish-brassy or brassy-gi'ecn, sliiuing, and sparingly besprinkled with a very tine cinereous 

 pubescence. Rostrum long and arcuated (though not quite so much cun'ed as that of the 

 A. chuhjheipenne) , — and with the antennae inserted into it about midway between its base and 

 apex. Prothoraw small, slightly rounded at the sides, and with its posterior margin straightly 

 truncated ; deeply and rugosely punctured, and with faint indications of a central chanucl. 

 Elijtra ovate, and creiiate- striated ; just perceptibly acuminated at their apex, — where each of 

 thcni is separately rounded-off; with the interstices most delicately rugulose and punctulatcd ; 

 usually of a more coppc-ry or brassy tinge than the prothorax (in which metallic-green is the pre- 

 vailing hue). Antenntc and leys rather long and robust, and nearly black, — displaying but a very 

 shght metallic lustre. 



Both the present Apion and the folloT\-ing one may be known from the species 

 here described by their antennte being inserted near to the middle of their rostrum, 

 instead of towards its base ; whilst, inter se, the more shining and metallic body 

 of the A. Wollastoni, which has its prothorax (although small) not quite so 

 minute or so cylindrical, in conjunction with its rather more pubescent surface,
