58 Mr, G. C. Champion's Revision of the Mexican 



head is nigro-setose behind the eyes. The colour of the 

 head and prothorax is probably variable, as in some of 

 the alUed forms. The sexual characters were in part 

 described by Gorham. 



15. Attains sexguttatus, n. sp, (Plate II, fig. 12, $.) 



$. Moderately elongate, %videned posteriorly, shining, the elytra 

 subopaque ; rufo-testaceous, the prothorax with a spot on each side 

 of the disc, and the elytra with a humeral patch and a subtriangular 

 mark on the outer part of the disc beyond the middle, black, the 

 terminal joint of the maxillary palpi, the antennal joints 4-11, the 

 tibiae (except at the base) and tarsi, and the upper edges of the 

 femora, infuscate or black; finely pubescent, and also set with 

 scattered, long, pallid, semi-erect, bristly hairs. Head transverse, 

 closely, very minutely pimctate, the eyes prominent ; antennae 

 rather slender, comparatively short. Prothorax small, transverse, 

 closel}', very minutely punctate. Elytra moderately long, broader 

 than the prothorax, much widened posteriori}', flattened on the disc 

 anteriorly, the humeri tumid ; rugulose, and densely, very minutely 

 pimctate. Legs long and slender. 



Length 3 mm. 



Hab. Panama, Tole {Champion). 



One example, found in January, 1883. This species 

 approaches one of the forms of the variable of A. rufifennis 

 (Gorh.), except that the elytra have an additional subapical 

 spot; the puncturing, however, of the whole of the upper 

 surface is finer and denser, the prothorax is smaller, and the 

 eyes are more prominent. A. maculosus has a much larger 

 head and prothorax, etc. 



16. Attalus pusillus. 



Anthocomus jnisiUus. Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, p. 116, t. 6, fig. 24. 



The two specimens from Cordova referred to this species 

 by Gorham are females. The one treated as a variety 

 (immature) is more shining than the selected t}^e, and has 

 the basal half of the head black, the black markings on 

 the elytra more extended (those at the base forming a 

 common fascia), and the puncturing of the elytral surface 

 sparser. There is no difference in size, both measuring 

 about 2i mm. in length.
