fragments of twigs boiled with the scales in caustic soda gave a 

 very fine madder color. 



Locality; Kingston, Jamaica ; received from Prof C. H. T. 

 Townsend, curator of the Jamaica Museum. 



The food-plant seems to be some ornamental shrub, and as I 

 did not meet with the scale in Jamaica, I infer that it is probably 

 a recent introduction from some other tropical locality. The 

 indistinctness of the plates, and the great thickness of the wax, 

 is in great contrast to C. cirripediformis, and reminds one of 

 C. ceriferus. From this latter it is distinguished not only by its 

 appearance, but by the rudimentary condition of the "tail." 

 The long fourth joint of the antenna in C. a/bolineaius is also 

 peculiar as compared with other species, but it requires to be 

 confirmed in specimens with better antennae. The present spe- 

 cies resembles C. psidii in its larger digitules, but it has a shorter 

 claw; it is distinguished from psidii at once by the absence of 

 the external markings of that species. From C. floridertsis it 

 differs entirely in appearance, and is also much larger; from C. 

 depressus it is distinguished by external features at a glance. It 

 cannot be C. jafnaicensis, which, though very imperfectly de- 

 scribed by White, has distinct plates after the manner of C. cir- 

 ripediformis. From the remaining described species of Cero- 

 plastes it is distinguished by characters which it is hardly worth 

 while to enumerate. 



A specimen has been sent for coll. Amer. Ent. Society. 



ON SOME PSELAPHID/E. 



By E. Brendel. M.D., Cedar Rapids, Iowa. 



There is before me a Pselaphid from the Dry Tortugas,' which, 

 according to A. RaflTray's classification, is a Bryaxis of a very 

 elongate depressed form, resembling in outlines the European 

 Trichonyx ; but by comparing the figures and the synoptical 

 characters given by Raffray, it seems to claim a place near the 

 Australian genus Briara Reitter. I give a description of it : 



BRIARAXIS Brendel. 

 Tarsi with one claw, trochanters obliquely inserted into the 

 femora, posterior coxae not conical, not prominent, with their 

 tnutual distance equaling twice the thickness of the femur; infe-
