length, very narrow, and a good deal of its area is covered by pine and eucalyptus 

 trees. Not many insects were taken on the island. This pentatomid was also 

 taken on Brandon Island, a very small rocky island in Departure Bay, and 

 perhaps a hundred yards from the Station. Only a very limited amount of 

 vegetation is supported by the soil, and at high tide the island is pretty well 

 covered by water. The bugs probably do not breed upon these small, rocky 

 islands, of which there are a great many in the region, but are probably blown 

 out or fly out from the main land. 

 Cosmopepla conspicillaris (Dall ) 



Several specimens of this spedes were usually taken on each collecting 

 trip. They were found more commonly in semi- cultivated areas. All the 

 specimens are uniformly marked so far as colour pattern is concerned, but the 

 transverse band across the pronotum varies in intensity from pale yellowish 

 white in some specimens to deep reddish orange in others. 

 Eysarcoris intergressus (Uhler). 



But a single specimen of this species, a female taken September 1, is repre- 

 sented in our material. This specimen is a little darker and has a more bronzed 

 appearance than the other specimens in my collection, which are from Colorado 

 and Washington. I believe that the species has not before been recorded from 

 the latter State. 

 Thyanta custator (Fabr.). 



This was the most abundant pentatomid of the region, and was taken on 

 ever>' collecting excursion between August 26 and September 12. Both pale 

 yellowish and the typical greenish individuals are among the lot, but in none is 

 the sanguineous band across the pronotum well marked, although it is evident 

 in some of the pale forms. This bug was common in open places in the woods 

 near the Station where a little clover and timothy were growing. Two speci- 

 mens were also taken on Brandon Island September 1. 

 Banasa dimidiata (Say). 



Seven specimens of this species were taken by us between September 1 

 and 6. All have the general body colour, a reddish brown with the anterior 

 lialf the pronotum yellowish green. In none of the examples is the second 

 segment of the antennae more than one-half the length of the third. 

 Elasmostethus cruciatus (Say). 



But one specimen of this species, a typically coloured female was taken on 

 September 1. 

 Podisus serieventris (Uhler). 



One adult female, taken September 1 and a nymph in the fourth instar 

 constitute our only records for the species. The adult example is dark reddish 

 in colour with the tips of the humeri and a spot on each hemelytron black.
