visibly but very minutely and closely punctured. The elytra are together wider than 

 long, the shoulders produced (but not so much as they often are in Chilocorus) ; blood- 

 red, very obsoletely and finely punctured ; the black scutellar mark is wanting in one 

 example, but in another the suture is very narrowly black ; the apex is occupied by a 

 large squarish black patch, returning a little up the suture, and in the specimen with a 

 black suture a little farther along the margin. The legs are coral-red. The front tibise 

 are simple, grooved externally for the reception of the tarsi, which are nearly as long as 

 the tibiae. 



Seven specimens were obtained, one of which is orange-red, but was obviously 

 captured when quite freshly emerged and soft. 



This species has the form of Curinus, and might have been placed in that genus, but 

 for its wholly different colour, and that I do not consider there are structural differences 

 to separate it from JExochomus. 



4. Exochomus tricoloratus. (Tab. X. fig. 8.) 



Transversim orbiculatus, niger ; capite albo, ore, pedibus abdomineque flavis, prothoracis lateribus late albido- 

 flavis, elytris crebre ac minute punetatis, macula subhumerali alteraque subapicali rotundata sanguineis. 

 Long. 4, lat. 4| millim. 



Hab. Nicaragua, Chontales (Belt). 



Head whitish yellow, the base black (but this part is generally hidden by the thorax), 

 the mouth and trophi yellow. Thorax black, with the sides white, this colour taking 

 the form of a round spot ; in one example there is a triangular white spot in front. 

 Elytra black, each with a small but very bright red spot at the shoulder, but not on the 

 base, and another near the apex ; in one specimen there is a minute red dot near the 

 centre of each elytron. The elytra taken together are wider than the whole length of 

 the insect ; epipleurse red, so as to correspond with the spots. 



We figure the example with two red dots on each elytron, and the thorax with a 

 white spot in front. 



Two specimens. 



5. Exochomus scapularis. (Tab. X. fig. 9.) 



Nigro-subcseruleus, subtus rufus ; epistomate, labro protboracisque margine laterali anguste runs, elytrorum 

 angulo antico, macula quadrata, margineque subapicali gutta parva laete sanguineis ; tibiis anticis angu- 

 lariter dilatatis. Long. 4 millim. 



Hab. Mexico, Jalapa, Vera Cruz, Tapachula in Chiapas (Hoge). 



Var. margine subapicali concolore. 



Hab. Mexico, Iguala in Guerrero (Hoge), Amula in Guerrero 6000 feet (H. H. 

 Smith) ; Nicaragua, Chontales (Janson). 



Head yellow beneath, and with the mouth, front, and trophi of the same colour, the
