252 Mr. W. L. Distant on Neotropical Pentatomldge. 



margins slightly sinuate, the lateral angles rounded ; scu- 

 tellum slightly wrinkled, sparingly punctate, rather more 

 than basal half slightly purplish in hue ; corium thickly, 

 very finely punctate; connexivnm ochraceous ; rostrum 

 reaching the posterior coxse, its apex black ; apical areas of 

 the posterior femora moderately infuscate. 



Long. 13^ mm. 



Hab. Guatemala (0. Salvin, Brit. Mus.). 



Allied to B.stalii, Dist., but difi'ering by the less punctate 

 head, the basal half of the central disk being impunctate, 

 levigate, third joint of antennae only a little longer than 

 second, lateral margins of prouotum slightly sinuate, different 

 coloration, &c. 



I have again used Stdl's genus, though in 1880 I referred 

 to the great difficulty with which it could be separated from

 distinct subgenus, the name is better treated as previously. 



Genus Disderia. 

 IHsden'a, Bergr. Eutomol. News, xxi. p. 20 (1910). 



Type, D. decorata, Dist. 



Tarsi three-jointed, second joint very small; scutellnm 

 " with the apical part moderately broad/' the apex not 

 rounded, but subangulate. 



D. deco7'ata appears to be widely distributed in Central 

 America. I have previously recorded it from Mexico, 

 Honduras, and Guatemala, and have since received it from 

 Nicaragua. 



Genus Oplomus. 

 Oplomus, Spill. Ess. Ileni. p. 365 (1837). 

 Type, 0. tripustulatus, Fabr. 



Oplomus stellatus, sp. n. 



Black, coarsely punctate ; anterior and lateral margins 

 (including lateral angles) and three large oblong spots to 

 pronotum, the central spot connected with the anterior 

 margin, a large oblique spot near each basal angle and the 

 apex to the scntellum, apical angle and a small suffusion near 

 middle of costal area to corium, basal spine and basal spot to 

 abdomen beneath, and a lateral segmental series of irregular 

 spots and lateral margins of sternum bright ochraceous j
