ACRASPEDON, gen. nov. 



Corpus elongatum. Processus mesosternalis elongatus, apice rccte 

 truncatus. Mandibulje extus bidentatae. Pronotum lateribus 

 immarginatum, angulatum, aiigulis fere rectis, margiue postico 

 lobatum, lobo truncate. Scutellum parvum, lateribus curvi- 

 lineatis, quam latum vix longius. Elytra profunde sulcata.

Burnieister's Section II. A of the genus Chlorota is at 

 present in a very disorganized condition. Lacordaire placed 

 its original members in the now restricted Antichira, but 

 related forms have since been described under both names. 

 They make a very heterogCTieous collection, agreeing in little 

 but the deeply striate elytra. The insects in question are 

 C. smaragdula, chalconota, iiietalUca^ and costata of Bur- 

 meister, C. Belli, Bates, C. associata, Waterhouse, Antichira 

 j)7-etiosa, De Breme, and A. crassa, Ohaus. Of these the 

 first has rightly been transferred to Antichh-a, being closely 

 allied to A. virens, Drury, the typical s})ecies according to 

 Dr. Ohaus's reconstitution of tlie genus. Chlorota associata^ 

 Waterh., is more closely related to Antichira pretiosa, De Br., 

 than to any of the insects with which it has hitherto been 

 grouped, and these two may conveniently be formed into a 

 new genus, distinguished chiefly by the structure of the claws 

 and the shape and size of the scutellum. 



^QUATORIA, gen. nov. 



Corpus eubhemisphffiricum. Clypeiis productus. Scutellum magnum, 

 elongatum, margine anteriore subtiliter convcxum. Pronotum 

 postico baud lobatum. 



FemiusB tarsorum mediorum et posticorum ungues simplices. 



Mas incognitus.

Dr. Ohaus has already pointed out the chief characters of 

 the group formed by Belti, Bates, costata, Burm., and crassa, 

 Ohaus, but without proj)osing a common designation. These 

 insects differ from Antichira in the form of the mandibles 

 and the scutellum, and from Chlorota in addition by the 

 long sternal process.
