62 SEEEICOENIA. 



the apical half is gradually inclined ; the apices are slightly divergent and finely denti- 

 culate. On each elytron there are the following black marks : — an ill-defined spot near 

 the base ; an oblong spot before the middle, near the suture ; and a short stripe behind 

 the middle, united posteriorly to a rather broader, slightly oblique band which joins the 

 margin, the stripe and the band together forming a letter L ; the apex is also black. 



The series of specimens from Guatemala have the apices of the elytra a trifle more 

 divergent than in the three individuals from Mexico ; but without a series from Mexico 

 I do not like to separate the two forms as species. 



6. Agrilus exustus. (Tab. IV. figg. 13, 13 a.) 



Elongatus, subparallelus, parum nitidus, confertim seulpturatus, cupreo-seneus, thorace fasciaque elytrorum 

 post medium lata griseo-purpurascentibus, abdomine purpurascente ; capitis vertice macula velutina 

 ferrugineo-nigra ornato; elytris obsolete marmoratis, ad apicem parum dilatatis, subtiliter serratis- 

 femoribus cupreis, tibiis tarsisque purpurascentibus.

This species somewhat resembles A. velutino-maculatus in general form and characters, 

 but is quite differently coloured. The head is shining, coppery-brass ; the upper part 

 of the forehead is rather deeply concave, with a moderately large dark brown (nearly 

 black) spot on the upper part ; the lower part of the face is longitudinally canaliculate 

 (the channel filled with whitish scales), with a very distinct somewhat round tumour on 

 each side of it, the upper part of the tumours being slightly flattened. The thorax 

 is finely punctured and rugulose ; the disc with a shallow oblong impression at the 

 base, and two indistinct impressions in front. The scutellum is moderately large and 

 distinct. The elytra are densely and finely punctured ; of an obscure brownish-brassy 

 colour at the base and apex ; the part behind the middle obscure greyish-purple ; the 

 apex curved down and also convex transversely. 



7. Agrilus inclinatus. (Tab. V. figg. 1, 1 a, b.) 



Brunneo-aeneus, hie et illic cupreo tinctus ; thorace disco minus dense sat obsolete punctato, medio impresso, 

 ad angulos posticos linea elevata introrsum directa instructo ; scutello leevi ; elytris postice gradatim 

 angustatis, apicem versus inclinatis, nitidis, cyaneo-eeneis (ad basin seneis, lateribus apieeque purpureo- 

 cupreis), subtiliter discrete punctulatis, maculis nonnullis albo-tomentosis ornatis, apice paullo dilatato et 

 dentieulato.

The top of the head is marked with numerous confluent flexuous impressed lines ; in 

 the middle there is a well-defined smooth channel, which widens out into a nearly round 

 impression in the middle of the face, and on each side of this there is a slight round 

 swelling ; the space above the clypeus is closely and rather strongly punctured ; the
