CURCULIONIDtE. ALOPHUS. 109 



Alophus is distinguished from the foregoing genera not only 

 by its form and structure, but by its habits ; the present insects 

 affecting dry and arid sandy heaths : the rostrum is shorter, the scu- 

 tellum, although small, is very distinct, the elytra are attenuated to 

 the apex, and the antennae rather more slender; the apex of the 

 tibiae is not furnished with a hook, and the tarsi are longer, and the 

 body is apterous. 



Sp. 1. triguttatus. Nigricans, coleopteris griseis, maculis tribus albidis, poste- 

 riori majore cordatd communi. (Long. corp. 3 — 4 lin.) 

 Cu. triguttatus. Fabricius. — Al. triguttatus. Steph. Catal. 171. No. 1744. 



Blackish ; clothed with pale griseous hairs : head obscurely punctured : thorax 

 with a deep dorsal line;, fuscous, immaculate : elytra slightly striated, the 

 striae composed of remote impressed dots, each with a rounded white spot to- 

 wards the base, and an arcuated one near the apex, reaching to the suture, and 

 forming by the union of the two a distinct V : legs piceous, with the tarsi 

 dull and ferruginous : antennse also duU ferruginous. 



Rather variable : in some cases the elytra are thickly varied with whitish or 

 cinereous clouds, at others they have only the white spots. 



Very abundant in the sand-pits on Hampstead-heath ; also near 

 Charlton in Kent, and at Hertford. " Raehills, common." — Rev. W. 

 Little. " Sand-hills (Swansea), common." — L. W. Dillwyn, Esq. 



Sp. 2. Vau, Griseus, oblongus, elytris maculd et figura V communi albis. 



(Long. corp. 3—4 lin.) 

 Cu. Vau. Schranck.—Don. xii. pi. 414./. I.— Al. Vau. Steph. Catal. 171. No. 



1745. 



Oblong, griseous, clothed with cinereous pubescence : rostrum thick, rather short : 

 thorax with a deep puncture on the disc anteriorly : elytra rather faintly 

 striate, the striae composed of remote punctures ; the disc of each with a white 

 spot behind the middle, and an oblique one towards the apex, the latter 

 forming by the union of the elytra a F-like mark : legs piceous, with the tarsi 

 rufescent : antennse also rufescent. 



Found with the preceding insect, of which I suspect it may be 

 only a variety of the female. 



Sp. 3. trinotatus. Niger, cinereo-pilosus, elytris fulvescentibus striatis maculd 



obscurd alhidd. (Long. corp. 3^ Un.) 

 Cu. trinotatus. Marsham MSS.—M. trinotatus. Steph. Catal. 171. No. 1746 



Black, with cinereous pubescence: thorax densely clothed with cinereous, with- 

 out an im,pressed point in the front of the disc : elytra attenuated, rather 

 clavate-striate, with the interstices punctate, the punctures slightly impressed; 

 clothed with dull fulvescent scales ; ivith an obscure whitish spot on each
