produced than the inner angle. The prosternal process is rather convex, finely and not 

 very closely punctured. The metasternum is extremely delicately punctured, and has 

 a stripe of golden-yellow at the side continued on to the posterior coxae. The meta- 

 thoracic episterna are nearly smooth, with the outer margin closely punctured. The 

 abdomen is finely punctured ; it has a stripe of golden-yellow pubescence on the upper 

 margin of the basal segment, and a rather large spot at the side of the second segment ; 

 there is also a straight stripe of pale pubescence on each side of the basal segment at 

 some distance from the side; the lateral carina of the basal segment is rectilinear 

 posteriorly, with a small notch behind the middle. 



Two of the examples from Cordova are smaller in size, and have the elytra 

 purple.

Supra fusco-cupreus, surdus ; subtus purpureo-cupreus, nitidus ; capite crebre punctato, fronte profunde exca- 

 vata ; thorace fortiter transversim striolato (striolis punctatis), disco longitudinaliter canaliculato- 

 impresso, impressione fusco-velutina ; elytris confertim fortiter subrugoso-punctatis, medio plaga oblonga 

 fusco-velutina ornatis, ad apicem divergentibus, margine apicali denticulato.

A very distinct species, having the apices of the elytra widely diverging. The male 

 has a stripe of yellowish pubescence along the whole length of the sternum ; the same 

 part in the female is bare, but densely punctured. There is a large patch of yellow 

 pubescence at the side of the metasternum (extending on to the coxae) in both sexes. 



15. Agrilus centralis. (Tab. V. figg. 3, 3 a, b.) 



Brunneo-seneus, nitidus ; capite excavato, antice binodoso ; tborace tenuiter punctulato, medio late profunde 

 canaliculato, canaliculo crebre fortiter punctato ; elytris tenuiter baud crebre punctulatis (ad suturam 

 crebrius punctatis), maculis sex parvis sordide flavis notatis, ad apicem ipsum perparum dilatatis, denti- 

 culatis, singulo elytro dente centrali validiore instructo ; pectore abdomineque fiavo-maculatis.

The head is broadly channelled or excavated, at the top as well as in front ; rather 

 strongly punctured, the vertex with curved lines of punctures ; at the lower part of the 

 face there is on each side an oblique node. The thorax is transverse, with the sides 

 gently arcuate ; finely but not very closely punctured and obscurely striolate ; the longi- 

 tudinal median impression has numerous curved lines of punctures ; the posterior ridge 

 is well marked, placed close to the margin, and curved outwards and downwards to the 

 margin (fig. 3). The elytra have the subcosta strongly marked but obtuse ; the punc- 

 tures on and outside the subcosta are fine and somewhat separated from each other, 

 those in the sutural area are stronger and a little closer together, but not crowded ; 

 the apex is a little wider than at the part just before it, the outer angle more or less
