9. Agrilus distans. (Tab. V. figg. 2, 2 «, b.) 



Yiridi-Eeneus, subtus brunneo-Eeneus, sat nitidus, creberrime asperato-punctatus ; elytris maculis sex albo- 



pubescentibus. 

 Long. 4 lin. 



Eab. Mexico, Oaxaca (Edge). 



The head has some closely placed converging curved punctured lines on the vertex ; 

 the face is rather strongly and closely punctured ; there is a very shallow impression in 

 the middle. The thorax has two very shallow inconspicuous impressions on the disc, 

 one anterior, the other posterior ; the punctures are moderately close together, trans- 

 versely elongate, and often united to each other transversely by fine lines ; on each side 

 of the front of the disc the surface is rather more rugulose ; the usual lateral impression 

 is brownish-aeneous, with some whitish pubescence at the anterior part ; the posterior 

 ridge is distinct, smooth — commencing from the angle and curving round, it nearly 

 touches the side about the middle. The elytra are closely and somewhat strongly aspe- 

 rate-punctate ; the subcosta is well marked and sculptured in the same way as the rest 

 of the surface ; the basal impression is well marked and slightly pubescent ; just before 

 the middle there is a spot close to the suture, and at some distance from the apex 

 another more elongate and whiter spot. The prosternum is very closely and rather 

 strongly punctured ; the episterna are closely punctured and clothed with pale grey 

 pubescence. The metathoracic episterna are rather closely and moderately finely 

 asperate-punctate. The abdomen is distinctly and not very closely punctured. The 

 lateral carina of the basal segment is distinctly angulated rather behind the middle, with 

 a small spot above (fig. 2 b). 



10. Agrilus squaliformis. 



Agrilus squaliformis, Thomson, Typi Bupr. p. 85 l . 



Eab. Mexico, Cordova, Puebla (SalU) ; Guatemala 1 , Duenas, San Geronimo 3000 

 feet (Champion), Chimaltenango (Conradt). 



This species has the lateral carina of the basal segment of the abdomen very strongly 

 angulated behind the middle. 



Three examples, two from Mexico and one from Guatemala, are of a beautiful steel- 

 blue colour instead of the usual brassy-aeneous. 



11. Agrilus divaricatus. (Tab. IV. figg. 16, 16 a, b.) 



Brunneo-aeneus, subtus cupreseens, nitidus ; capite antice longitudinaliter sulcato, macula flavo-pilosa ornato ;. 

 tborace crebre subtiliter punctulato, transversim aciculato, disco medio sat profunde sulcato; elytris 

 postice bene attenuatis, ad apicem parum divaricatis et cupreis, regione suturali impresso et creberrime 

 punctato; abdomine medio quam elytra latiore, supra utrinque macula magna flavo-pilosa ornato; 

 episternis metathoracis flavo-pilosis.
