specific with Metacanthus capitatus of Uhler and there certainly 

 is nothing in the descriptions to distinguish the two species. 

 Dr. Uhler's new genus Protacanthus, established for decorus, 

 seems to differ from Metacanthus elegans only in having the 

 rostrum a little longer and the spines at the anterior angles of 

 the pronotum longer and more slender. 



Family Lygaeidae 



Oncopeltus pictus n. sp. 



Closely allied to varicolor. Orange fulvous marked with black and 

 white. Head fulvous, apex of the tylus base of the vertex, occipital area, 

 and antenniferous tubercles black; Antennae black, proportionately shorter 

 and thicker than in varicolor, second joint perhaps a little longer relatively. 

 Rostrum black, shorter than in its ally, scarcely attaining the apex of the 

 first ventral segment. Pronotum narrower than in varicolor with the lateral 

 margins rectilinear, not arcuated ; humeral angles not rounded; depressed 

 basal margins narrow and broadly rounded, not broad and subangularly pro- 

 duced as in varicolor; color fulvous, base, sides, and median line black. 

 Scutellum black. Elytra black with a large white spot on the base and 

 another at apex, omitting the costal nervure, the apical spot obliquely pro- 

 duced and arcuated anteriorly ; not cut square across as in varicolor. 

 Beneath fulvous; meso- and meta-sternum, except their posterior margins, a 

 cloud exterior to the coxae, much smaller on the pro pleura, edge and apex 

 of the venter and a discal area, which scarcely attains the base and extends 

 to the margins on the fifth and sixth segments, black. Tergum apparently 

 coccineous with the apex, narrow lateral margins, and a transverse vitta on 

 the posterior segment, black. L,egs black. Length: male, 10; female 12 mm. 



Described from a single pair taken on the northern side of 

 the island; the male at St. Margaret's Bay; the female at Hope 

 Bay. , 



This species may vary in color as does its ally but the dif- 

 ferent form of the pronotum, as well as the shorter antennae 

 and rostrum will distinguish the species. It is also smaller and 

 has the elytra proportionately narrower at base. My specimens 

 of varicolor are from the island of Trinidad and agree very 

 closely with Distant's figure in the Biologia. 



Oncopeltus gutta H. S. 



One male swept from weeds by the railway tracks near the 

 Kingston station, April 17th. This corresponds with Distant's 

 Biologia figure except that the ground color is a light scarlet 

 including the entire head except the apex of the tylus and a 

 cloud behind the ocelli, and the sides of the scutellum.
