AcRASPEDONj gen. nov. 



Corpus elongatum. Prooeasus mesosternalis elongatus, apice recte 

 truncatus. Mandibular extus bidentatse. Prouotum lateribus 

 immarginatum, angulatum, angulis fere rectis, margiue postico 

 lobatum, lobo truncato. Scutellum parvum, lateribus curvi- 

 lineatis, quam latum vix longius. Elytra profunde sulcata. 



Type : Acraspedon {Antichira) sulci'pennis, Waterh., Trans. 

 Ent. Soc. Lond. 1881, p. 543. 



Burmeister's Section II. A o£ tlie genus Ghlorota 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 heterogeneous collection, agreeing in little 

 but the deeply striate elytra. Tlie insects in question are 

 C. smarogdiila, chalconota, vietallica, and costata of Bur- 

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

 pretiosa, De Breme, and A. crassa, Oliaus. Of these the 

 first has rightly been transferred to Antichira, being closely 

 allied to A. virens, Drury, the typical species according to 

 Dr. Ohaus's recoustitution of the genus. Chlorota associatay 

 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. 



jEquatoria, gen. nov. 



Corpus subhemisphsericum. Clypeus productus. Scutellum magnum, 

 elongatum, margine anteriore subtiliter convexum. Pronotum 

 postico baud lobatum. 



Femiuse tarsorum mediorum et posticorum ungues simplices. 



Mas incognitus. 



Type: JEquatoria (^Chlo7-ota) associata, Waterh., Trans.

Dr. Ohaus has already pointed out the chief characters of 

 the group foimed by Beltt, Bates, costata, Burm., and crassa, 

 Ohaus, but without proposing a common designation. These 

 insects differ from Antichira in the form of the mandibles 

 and the scutellum, and from CIdorota in addition by the 

 long sternal process.
