djiboutensis Coutiere and Martin occurs in the Red Sea (Gulf of 

 Aden), and hawaiiensis China is known from Oahu, Hawaii. The 

 new species described below from Dominica Island, British West 

 Indies, represents the first record of this genus from the Atlantic 

 Ocean. A second new species from Central Polynesia (Tuamoto 

 Archipelago) is also described. 



Esaki (1947) has given an interesting account of the habits of 

 H. haddoni. It inhabits coral reefs and at low tide skates about on 

 the surface of tidal pools and in the small pools of water contained 

 in dead Tridacna mollusk shells, where it apparently feeds on CoUem- 

 bola, marine midges, and perhaps on water striders of the genus 

 Halovelia. As the tide comes in, Hermatobates conceal themselves in 

 the crevices of the coral, underneath blocks of loose coral, or in dead 

 Tridacna shells so that at high tide these water striders may be 

 submerged under 10 feet or more of water. 



In addition to the type material described below, I am depositing 

 my collection of Hermatobates (15 specimens, mostly females and 

 nymphs) in the U.S. National Museum. 



I take great pleasure in naming the following new species for 

 Mr. Bruce Bredin, who sponsored the Smithsonian-Bredin Expeditions 

 to the West Indies in 1956 and 1958. 



Hermatobates bredini, new species 



Figure 1 



A small brown species with antennal segments in proportion 

 12:13:8:11. Anterior trochanter, femur, and tibia without teeth 

 or spurs. Posterior margin of metasternum straight without median 

 prominences, armed only with minute teeth. 



Holotype male. Head viewed from above transverse, width across 

 eye level four times greatest length; triangular; antenniferous tubercles 

 not prominent nor visible from above; eyes small, with short erect 

 bristles, ocular width about one-quarter that of vertex between eyes 

 (4 : 17), this distance twice as great as length of head seen from above 

 (17:7); covered with pale pubescence and longer tufts on apex and 

 sides; frontal suture running close to base of head, sinuate, extending 

 forward laterally, area between it and eyes flattened; clypeus promi- 

 nent between antenniferous tubercles. Antenna densely covered 

 with fine pubescence, relative lengths of segments 12:13:8:11. Ros- 

 trum extending a little beyond the bases of the anterior trochanters, 

 relative lengths of segments 6:2:5:4. 



Pronotum very short, little more than half the width of an eye, 

 widening behind eyes, pubescence dense and fine. Fused meso- and 

 metanotum and abdominal segments dull with short pubescence on
