cavata; elytris postice purpureis; abdomine segmentis 



crebre antice punctulatis. 

 Long. 4 lin., lat. J lin. 



This may be a small variety or one of the sexes of A. Bon- 

 vouloiru] but there are one or two points of distinction which 

 seem to me to warrant its being provisionally described as dis- 

 tinct. It is smaller, and the elytra are purple behind, that 

 colour encroaching more or less on the green at the base ; the 

 head is more deeply excavated ; the scutellum is bi-ridged 

 transversely at the base, and the segments of the abdomen are 

 finely and closely punctate along the anterior margin. 



Several specimens have been received. I am informed by 

 Mr. Edward Saunders that in some cabinets it stands under 

 the unpublished name of A. capensiSy which I have preserved. 



4. Agy-ilus Saundersii. PL VIII. fig. 2. 



jEnescenti-olivaceus, apice parum cupreo ; elytris punctis, sex 

 albido-pilosis (duobus ad basin, duobus ante medium, duo- 

 bus propinquioribus post medium) instructis. 

 Long. 3 J lin., lat. | lin. 



In general appearance similar to Agrilus sexguttatuSj but 

 smaller and narrower in proportion, also similarly marked 

 with six small spots of white scales. Brassy olivaceous, 

 slightly coppery at the apex of the elytra ; surface finely gra- 

 nulous. Head with the forehead very prominent, and with a 

 longitudinal groove separating it into two lobes. Thorax sub- 

 quadrate, slightly widest in front, transversely finely acicu- 

 larly rugose, behind with a broad transverse curved depression 

 concave to the front, with a slightly deeper impression in the 

 middle and another on each side. There is also a some- 

 what curved impression near the middle in front ; median 

 lobe short, curved. Scutellum small, triangular. Elytra 

 finely granular, with a small depression, full of whitish scales, 

 at the inner angle of the shoulder ; and a larger median 

 depression, filled with whitish scales, somewhat before the 

 middle, and a still larger one (although all actually small) 

 behind the middle and closer to the suture ; the apex doubly 

 emarginate, more deeply next the suture, with a large tooth 

 at the sutural angle and another at each of the external angles : 

 exterior to this external tooth there are one or two minute 

 denticulations. Underside and legs greenish brassy, sparingly 

 clothed with a longish whitish pubescence. The upper margins 

 of the segments as seen beyond the elytra clothed with whitish 

 pubescence. Posterior tarsi with the first article equal in 

 length to the three following ; in the anterior tarsi the first 

 article not quite so long.
