188 SUPPLEMENT. 



the whole of the subsequent numbers after page 59 was printed. The following 

 alterations in my table of the species is now rendered necessary : — For nos. 46-89 read 

 46-90, for 90-91 read 91-92, and in all cases read one number higher to 141. 



l (a). Agrilus pilosus. (Tab. IX. fig. 17.) 



Cupreo-aeneus, parum nitidus, confertim punctatus, flavo-griseo-pilosus ; capite ruguloso, antice impresso ; 

 thorace subquadrato, transversim ruguloso, disco antice paullo gibboso medio impresso, basi medio 

 bi-impressa, lateribus leviter arcuatis ; elytris postice paullo declivis, haud costatis, pube flavo-grisea 

 ornatis, ad apicem sat acuminatis, apice ipso cupreo serrulato. 



Long. 4| lin. 



Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Smith). 



This is a dull, closely sculptured species, clothed above and below with short sandy 

 pubescence, which forms spots and bands on the elytra. The head is impressed in 

 front, with a very slight swelling above each antennal socket, the vertex with close, 

 oblique, punctured grooves. The thorax is a little broader than long, scarcely more 

 narrowed in front than at the base, punctured, and closely obliquely rugulose; the 

 disc is raised anteriorly (the middle of the anterior margin arched forwards), with an 

 oval impression on the highest part. The elytra at the base are as broad as the 

 thorax, slightly narrower below the shoulders, again broader behind the middle, 

 and then narrowed to the apex ; slightly flattened on the disc ; densely rugose ; the 

 pubescence forms the following markings : — a patch at the scutellum, two small spots 

 at one-third from the base, a fascia at the middle, a broader fascia at a short distance 

 from the apex, and two small spots just before the apex. The prosternal chin-piece is 

 short and very distinctly emarginate. The prosternum is closely rugose, lightly impressed 

 in the middle. The metathoracic episterna are closely punctured. The abdomen has 

 the pubescence somewhat congested at the sides, forming vague spots ; the apical margins 

 of the segments are smooth, and there is a smooth spot at the side of the apical 

 segments; the lateral carina of the basal segment is slightly angularly bent at the 

 middle. 



Agrilus oculatus (p. 60). 



To the Mexican locality given, add : — Chilpancingo in Guerrero 4600 feet (H. H. 

 Smith). 



Agrilus distans (p. 64). 



To the Mexican locality given, add : — Amula in Guerrero 6000 feet (H. H. Smith). 



The specimen from Amula, probably a male, is altogether a little narrower than the 

 type. It has the spots on the elytra (especially the posterior one) more elongate. The 

 abdomen has a conspicuous pale yellow spot at the side on the upper margin of the 

 basal segment, and the lateral carina here is more deeply sinuate than in the type.
