The head is longitudinally sulcate, and in two of the examples is impressed at the 

 upper part of the face ; densely punctured, the punctures having a tendency to form 

 oblique lines. The thorax is rather broad in front, narrowed posteriorly to near the 

 posterior angles, not very convex ; striolate, each striola having a puncture in it, slightly 

 rugulose towards the sides anteriorly ; the disc has a small round impression in front, 

 and there is a less distinct longitudinal one at the base ; the sides are impressed and 

 have a broad band of yellow pubescence ; the posterior ridge is absent. The elytra 

 are moderately closely punctured with cuneiform punctures ; the subcosta is tolerably 

 well marked, slightly curved at each of the yellow spots ; each elytron has three 

 yellow spots — the first is in the basal impression, the second is rather elongate and placed 

 before the middle, and the third is similar and placed halfway between the second and 

 the apex ; the apex is rounded and has a few small teeth. The prosternal chin-piece 

 is arcuate. The prosternum is closely rugose; the intercoxal process is obliquely 

 narrowed at the apex, with the central process at a lower level. The episterna 

 are entirely covered with yellow pubescence, which extends also to the posterior angle 

 of the metasternum and on to the posterior coxae. The abdomen has an elongate yellow 

 sj>ot on the upper margin of the basal segment, and a transverse spot at the side below, 

 with a contiguous longitudinal spot at its inner end; the second segment has an 

 elongate spot on its upper margin and a triangular spot below ; the lateral carina 

 of the basal segment is somewhat curved at the lateral spot. 



One example has the intercoxal prosternal process and the metasternum more finely 

 rugose than the others, and with very fine yellowish-grey pubescence ; the metasternum 

 has only a very fine indistinct median line instead of a very distinct one as in the other 

 examples ; and the basal segment of the abdomen is longitudinally impressed in the 

 middle. These are no doubt sexual differences, but they do not correspond with the 

 difference above-mentioned in the frontal impressions. 



120. Agrilus striativentris. (Tab. VI. figg. 24, 24 a.) 



JEneus, nitidus ; capite lato, crebre punctato, antice virescente, medio canaliculate, oculis prominulis ; thorace 

 convexo, postice angustato, creberrime punctato et oblique tenuiter ruguloso, lateribus postice impressis 

 virescentibus ; elytris postice parum angustatis, crebre subasperato-punctatis, singulis ad apicem rotundatis, 

 denticulatis, macula parum conspicua ante medium, altera post medium pallide flavis ornatis ; abdominis 

 segmento basali basi impressa, longitudinaliter tenuiter striolato.
