4. Ammophila argentea. 



Silver-fronted Sandwafp. 



A. antennis quatuordecirn-nodiis ; abdominis petiolb uniarticu- 

 . lato ; alis corpore brevioribus. 



Caput nigro-villofum. Maxilla acumine fufco. Antenna thoracis 

 fere longitudine. From planiufcula, infra antennas pilis 

 denfis decumbentibus argenteo-nitidiflimis, nifi a. tergo vix 

 confpicuis, tecta. 



Thorax anguftus; fubvillofus uti pectus villis certo fitu argenteis. 

 Squama nigras. 



Ala lubhyaimae, 1 apice obfeuriores, nervis 'ferrugineis ; abdomine 

 dimidio fere breviores. 



Abdomen clavatum, fegmento primo filiformi nigro; fecundo cam- 

 panulato tertioq'ue rufis; quarto rufo, apice nigro j reliqiiis 

 nigrxs. 



Pedes fetulis brevibus afperi. 



Long. corp. lin. 5-j. 



Semel capta, fed ubi et quando nefcio. 



At fir ft fight one would take this fpecies for A. vulgaris # but 

 upon a nearer infpeclion it will be found very diftinft. The front 

 has no fovea, and from the antennx downwards is quite covered with 

 a coat of (iiver pile, which, when the light falls upon it from above, 

 gives it a very glittering appearance. From the midft of this pile 

 other longer black hairs, thinly (battered, arile. The antennae 

 confift of fourteen joints, counting the minute 'one at their bafe. 

 The villi of the trunk glitter in certain lights,- but not fo much as 

 the pile on the front : the footftalk of the abdomen confifts of a 



fingle
