femora are infuscated, with a pale spot before their apex; the 

 females are nearly black with the pale pectoral vitta almost 

 obsolete ; the venter is black with a few pale points on the sides, 

 legs blackish with the tibiae and base of the femora pale; the 

 basal joint of the tarsi is ringed with pale and there is a pale 

 spot on the front of the posterior femora near the apex. A 

 good series in my collection from the island of Trinidad exhibit 

 variations in both sexes from the darkest individuals to the pale 

 form described by Stal. 

 Harmostes serratus Fabr. 



This species was not uncommon on the island. I took it 

 at Mandeville, St. Margaret's Bay, Troja, and Richmond. These 

 specimens are larger and darker in coler than some sent me 

 from the island of Trinidad by Mr. Chipman. 



In my collection I find a single example from Brownsville, 

 Texas, that differs from serratus in being smaller, paler in color, 

 and in having the second joint of the antennas equal to the third 

 and the rostrum barely attaining the intermediate coxae. These 

 characters are just those given by Dallas to distinguish his 

 affinis from serratus and I think it quite likely that it may be 

 the form described by him. 

 Corizus pictipes Stal. 



A very abundant insect everywhere I collected on the 

 island. Mr. Chipman sent me large numbers from Trinidad 

 showing it to be equally common there. I have also received 

 it from Mexico and Florida. 

 Corizus hyalinus Fabr. 



I took this with the larvae at Hope Bay. It may be abun- 

 dant later. It belongs to subgenus Liorhyssus Stal. 

 Jadera sanguinolenta Fabr. 



One example taken in a house at Mandeville. I saw broken 

 remnants in spider webs about houses in several places, so, 

 apparently, the season for its occurrence had about passed. Mr. 

 Reinecke took it in Jamaica in February and I have specimens 

 taken in British Guiana by Mr. Crew. 



Family Metacanthidse 



Jalysus reversus n. sp. 



Close allied to macer Stal. Pale ochraceous. Head with the basal 

 collum and three longitudinal lines pale; the lateral interrupted by the
