74. Agrilus lsetulus. (Tab. V. figg. 25, 25 a-d.) 



Cyaneo-viridis, nitidus ; tborace tenuiter striolato, medio bi-impresso ; elytris crebre rugosis, vitta brevi ante 

 medium (extus ad apicem macula parva aucta) plagaque ante apicem transversa griseis ornatis, apice 

 obtuse rotundato et denticulato.

The head is rather flat in front, closely and somewhat strongly punctured, the punc- 

 tures confluent transversely at the lower part ; the top of the head is longitudinally 

 striolate. The thorax has two discoidal impressions, one anterior, the other posterior, 

 both moderately deep and wide; the posterior ridge is distinct near the margin, 

 slightly thickened anteriorly, curved downwards, but not reaching the margin (fig. 25 a). 

 The elytra have the subcosta very distinct (but not at the base, w r here the surface is 

 convex), parallel with the suture to near the apex, then turned towards the suture ; 

 the apex of each elytron is subtruncate, distinctly denticulate (fig. 25 d). The pro- 

 sternal chin-piece is gently but distinctly emarginate in the middle. The prosternum 

 is scarcely pubescent, finely and not very closely punctured ; the intercoxal process 

 is gently convex in the middle, the margins slightly raised, acuminate at the apex 

 (figg. 25 b, c). The metasternum has a deep median channel. The episterna are 

 sparsely pubescent exteriorly, shining and very obscurely punctured on the inner half. 

 The abdomen is not very closely punctured, the intercoxal process acutangular ; there 

 is a slight whitish spot at the side of the second segment ; the lateral carina of the 

 basal segment is scarcely sinuous behind the middle. 



This species much resembles A. fasciolatus, Chevr., from Brazil. 



75. Agrilus consimilis, (Tab. VI. figg. 1, la-c.)

This species so closely resembles the preceding that at first sight it might be taken to 

 be a mere variety of it. The head is more arched in front and very delicately punctured, 

 the vertex with a somewhat deep longitudinal impression. The thorax is rather finely 

 punctured, and is very finely striolate only towards the sides ; there is a very deep 

 central impression at the base (with some white pubescence) and a very indistinct one 

 in front. The elytra have the subcosta scarcely indicated, the surface being flat ; each 

 has a small elongate spot before the middle, and between this and the apex there is a 

 second more distinct spot ; the apex of each is obtusely rounded and denticulate (fig. 1 a). 

 The prosternal chin-piece is gently arcuate. The prosternum is obscurely punctured, 

 clothed with fine whitish pubescence ; the intercoxal process is flat, not margined, 

 almost truncate at the apex (figg. 1 #, c). The metasternum has an impressed median 

 line. The abdomen has some sparse whitish pubescence, which is very long on the
