Ladoria desarmata, apart from the generic character, very much resembles Azya 

 luteipes ; but is usually of a more obscure tint, and the denuded patch on the elytra 

 is common to both on the middle of the suture. The type is in the Cambridge collec- 

 tion, and the examples I refer to this species agree with it. Crotch 2 quotes other 

 South-American localities, but the examples in his collection on which these were 

 founded must be referred to other species. 



2. Ladoria delphinse. (Tab. XI. fig. 25.) 



Orbicularis fere hemispbsericus, dense tenuiter griseo-pubescens, fulva ; prothoracis disco elytrisque obscure 

 cyaneis, bis anguste rufo-marginatis juxta suturam quasi denudatis ; metasterno abdominisque basi 

 nigricantibus. Long. 4-5 millim. 



Eab. Mexico, Vera Cruz, Toxpam (Salle), Acapulco, Jalapa, Oaxaca (Edge), Teapa 

 in Tabasco (H. H. Smith). 



Head, thorax, and elytra very finely and closely punctured, thickly clothed with a 

 short grey pubescence, which reflects the light differently as the insect is viewed, so that 

 the upper part appears more denuded of pubescence than it really is. The head and 

 the sides and front margin of the thorax are red in all the examples that I have seen, 

 and the elytra are very narrowly margined with the same colour ; occasionally the disk 

 of each elytron is very indeterminately reddish. The body beneath and legs are wholly 

 red, with the exception that the middle of the metasternum is blackish, and in some 

 examples this colour extends to the base of the abdomen. There are three examples 

 of this species in Salle's collection bearing the name under which I describe it ; Hoge 

 sent about six, three of which were from Acapulco, and Mr. H. H. Smith obtained one 

 at the latter locality. 



Ladoria delphince is on the average larger than L. desarmata ; it is clothed with a 

 very fine but dense grey pubescence, the sutural region alone appearing black and 

 shining. 



We figure a specimen from Toxpam. 



EXOPLECTRA. 



Exoplectra, Cbevrolat, in d'Orbigny's Diet. Univ. d'Hist. Nat. v. p. 545 (1844) ; Mulsant, Spec. Col.

The Exoplectrw are often very like Azyoe, but some are of a different colour, being 

 red all over and with spotted elytra. They have the tibiae dentate, but the claws are 

 bifid, and the tooth is of a different kind from that in Azya, being a broad, angular
