Thyanta perditor Fabr. 



Abundant everywhere on the island especially in the dryer 

 localities about Kingston and at Mandeville and Balaclava. In 

 my collection are specimens from Hayti, Mexico, Columbia and 

 Peru. This species seems to be more constant in coloration 

 than custator. All the examples before me have the pronotal 

 band distinct, anterior to which are two round black points, and 

 the edge of the abdomen is fulvous with a black point at each 

 incisure. The base of the head between the ocelli and a 

 median line on the tylus are rufous; there are generally a few 

 brown points near the base of the membrane. The pronotal 

 angles in all my specimens are acute and distinctly inclined 

 forward. 



Thyanta antiguensis Westw. 



I swept five examples of this species from a low whitish 

 succulent weed, apparently allied to Chenopodium, growing in 

 masses along the roadside to Rock Fort. These agree in every 

 particular with the material from Hayti described in my List of 

 the Pentatomidse of North America. 



Loxa flavicollis Drury. 



I took numbers of this large Pentatomid on the dry hot 

 hillsides above the Rock Fort quaries. Most of these were 

 beaten from Acacia bushes, March 25th. On April 17th I 

 found the larvae with the adults near Hope Gardens. 



Loxa pallida n. sp. 



Closely allied to flavicollis but smaller and narrower with the ground 

 color a paler yellowish green, that may in part be due to immaturity. Trans- 

 verse rugse on the vertex and cheeks much less distinct, these surfaces much 

 more strongly punctured with rufous; calloused outer margins of the cheeks 

 before the eyes rectilinear or very feebly concavely arcuated, not distinctly 

 bowed outward as in flavicollis, with their apex a little more slender and 

 acute before the tylus. Surface of the pronotum, scutellum and elytra very 

 uniformly and closely covered with rufous punctures arranged in anasto- 

 mosing transverse lines, between which are a few pale calloused points. In 

 flavicollis the punctured lines are farther apart with the intervening surface 

 minutely shagreened and irregularly blotched with pale, as is also the apex 

 of the scutellum and the disk of the corium. Humeral spines proportion- 

 ately a little more slender than in flavicollis, and the abdomen narrower; 

 the connexivum scarcely projecting beyond the elytra, pale, punctured with 

 rufous inwardly as in that species. Lower surface a little more closely 

 punctured with rufous; the apical spines on the outer genital plates of the 

 female more abrupt and slender. Antennae and legs pale with no indications
