^GITHUS. 91 



to the anterior angles ; and the base is not so much angulated, but almost straight 

 (though slightly bisinuate) and with a broad and indistinct median lobe. The elytra 

 are very smooth and glabrous and have numerous rows of fuscous dots ; the punctures 

 are larger and more distant than in JE. strigicollis, and eight rows are visible though 

 they terminate at one third from the apex. The underside and femora are rather paler 

 ferruginous-red than the upperside usually is, glabrous, and shining. The presternum 

 is not compressed but convex ; the metasternal lines are distinct, and produced back- 

 wards till they unite with the marginal impressed stria. 



This and some other allied species might from the form of the thorax be placed with 

 equal propriety in Brachysphenus, the V-shaped form having quite merged here into 

 the ordinary form. JE. dubius is, however, clearly allied to JEgithi of the JE. mono- 

 chrous and M. lineola group ; and there is really no other distinction than that of 

 general form between the two genera. 



Five specimens from Bugaba and one from Caldera. 



17. iEgithus stillatus. 



Breviter ovatus, convexus, flavo-ferrugineus, nitidus ; capitis puncto, antennarum clava, prothoracis lineis 

 tribus et limbo laterali, scutello elytrorumque punctis numerosis, sutura margineque tenuiter, nigris ; 

 elytris punctulis impressis, punctis nigris cingentibus, interdum obliteratis. Long. 6-7^ millim. 



Hab. Mexico (Salle) ; Beitish Hondueas, Belize (Blancaneaux). 



This is a very curious species, not allied to any other known to me ; but from the 

 numerous black dots on the elytra recalling 2E. burmeisteri. The head and thorax are 

 smooth and shining — of a rich fulvous-red in the Mexican example, yellowish in the 

 Belize specimens. The antennae have a four-jointed club ; these joints and one or two 

 preceding them are black, the basal joints being testaceous. The elytra are brownish- 

 yellow (as in 2E. punctatissimus and 2E. burmeisteri) ; the suture and lateral margins in 

 the Mexican example being of the rich red colour of the thorax, but in the Belize 

 specimens very narrowly black. The legs and underside are fulvous, the tibiae exter- 

 nally and the tarsi infuscate, the episterna pitchy. The metasternal lines are visible. 



Two specimens from British Honduras and one from Mexico are all I have seen of 

 this species. 



18. ^Sgithus (?) grammicus. (Tab. V. fig. 3.) 



Ovatus, valde convexus, nitidissimus, glaber, saturate flavus; antennis (articulis duobus pnmis exceptis), 

 prothoracis maculis quatuor oblongis, transverse sitis, scutello, elytrorum sutura, macula communi 

 suturali et tribus aliis irregularibus, genieulis, tibiis tarsisque, nigris. Long. 7 millim. 



Bab. Guatemala, Sabo, San Juan in Vera Paz (Champion). 



Head and thorax smooth, yellow, the former inclining to ferruginous and pitchy at 

 the base ; the latter with four elongate pitchy-black spots, its sides much narrowed 

 from the base, the front margin almost semicircularly cut out, the base angular.
