49. Agrilus molestus. (Tab. V. figg. 20, 20 a-c.) 



iEneus, parum nitidus ; capite antice obscure cupreo, rugoso, clypeo macula triangulari flavo-pilosa impresso ; 

 thorace irregulariter transversim vermiculato-strigoso, margine antico cupreo, disco bi-impresso, lateribus 

 antice flavo-pubescenfcibus ; elytris sat fortiter rugosis, maculis sex aureo-pubescentibus ornatis, apice 

 acuminato, denticulato.

Hab. Panama, Tole (Champion). 



The front of the head is very slightly convex ; the triangular impression above the 

 clypeus extending to about the middle ; when viewed from the front a very slight 

 impression may be seen at the upper part of the face, but it is not visible from above. 

 The thorax has the sculpture consisting of numerous short (more or less transverse) 

 curved lines, crossed at intervals by some finer oblique striolae ; of the two impres- 

 sions on the disc the posterior one is the larger and deeper — in some lights they appear 

 confluent ; the posterior ridge is near the side, and it is curved outwards and downwards 

 to meet the margin about the middle (fig. 20 a). The elytra have the subcosta very 

 little raised ; the pale golden-yellow spots are in the sutural area — the first extends 

 from the base to about one third the length of the elytron, the second is considerably 

 behind the middle, and the third is linear at the apex; the apices are angular (fig. 20 c). 

 The metathoracic episterna are closely punctured and pubescent. The sides of the 

 sterna are clothed with pale golden-yellow pubescence, and there is a spot of the same 

 colour on the upper margin of the basal segment of the abdomen, and a spot at the 

 side of the second and of the third segments. The lateral carina of the basal segment 

 of the abdomen is sinuate about the middle (fig. 20 b). 



50. Agrilus bicarinatus. 



Cuprascens ; capite crebre punctato, antice sulcato ( tf viridi) ; thorace convexo, transversim ruguloso, medio 

 sulcato, angulis posticis carina nitida distincta fere recta instructis ; elytris olivaceo-tinctis, maculis sex 

 griseis minus distinctis ornatis ; peetore griseo-pubescente ; abdominis segmentis secundo tertioque macula 

 flavo-grisea parum distincta ornatis.

 Guatemala, Chacoj and Teleman in Vera Paz, Zapote (Champion). 



This species much resembles A. molestus ; but it has the spots on the elytra somewhat 

 differently placed, and is at once distinguished by having the posterior ridge of the 

 thorax directed straight forwards instead of carved outwards. The head is slightly 

 convex in front, rather less so in the male than in the female, strongly and closely 

 punctured in the female, the punctures arranged in curved lines on the vertex ; in the 

 male the punctuation of the front is finer, and the surface less shining ; at the 

 top of the face there is a somewhat deep impression which is continued down the 

 face as a slight channel. The thorax is somewhat narrowed before the base, the 

 posterior angles slightly diverging ; the channel in the middle is well marked and
