area ; the subcosta is raised, shining and less closely punctured ; the sides are finely 

 asperate-punctate. The prosternum is finely punctured in front, strongly and less 

 closely punctured posteriorly. The sides of the basal segment of the abdomen are not 

 very closely punctured, and the punctuation is obscure ; the next segment has a large 

 spot of somewhat golden pubescence at the side; the lateral carina of the basal 

 segment alters its direction posteriorly (fig. 11 a). 



28. Agrilus squamulatus. 



Fusco-cupreus, subsurdus, thorace senescente ; capite antice dense rugoso flavo-pubescente ; thorace crebre 

 fortiter transversim striolato, disco longitudinaliter impresso; elytris creberrime rugosis, maculis octo 

 sordide flavis ornatis, ad apicem paullo ampliatis, denticulatis, singulo in medio dente majore instructo ; 

 corpore subtus plus minusve sordide flavo-pubescente. 



Long. 4-5 lin.

The head is very gently concave in front. The thorax has the discoidal impression 

 distinct but not very deep, constricted before the middle, the anterior portion smaller 

 than the posterior ; this impression (as well as the lateral one) is filled with dull 

 yellowish pubescence ; the posterior ridge is sharp and well defined, curved outwards 

 and joining the margin about the middle. The elytra in a fresh specimen would 

 probably be almost entirely powdered with yellowish pubescence (in most of our 

 specimens the sides are more or less pubescent) ; there is a spot in the basal impression, 

 one before the middle, a more distinct one considerably behind the middle, and a 

 streak at the apex. The prosternum is closely punctured and pubescent. The meta- 

 sternum is pubescent except in the middle. The abdomen is broadly pubescent at the 

 sides of the basal and second segments. 



This species was received with the manuscript name " A. squamulatus, Deyr.," 

 attached. An example in the British Museum is labelled " A. ccelaticollis, Laf." 



29. Agrilus laticaudatus. (Tab. V. figg. 9, 9 a). 



Prsecedenti affinis et similis. Latior, depressus ; elytrorum apice latiore.

This species closely resembles A. squamulatus, but is rather broader and a little 

 more depressed. The elytra are much more dilated at the apex, finely denticulate and 

 with no distinctly larger tooth, but with a very small sinuosity at a little distance from 

 the suture (fig. 9 a).
