feet. Moreover, the posterior portion of the tergite is not ele- 

 vated and the transverse sulcus is continued over the dorsum 

 as a distinct stria. In the male the anterior legs are much leas 

 swollen than in B,. macropus. 



Number of segments up to 54. 



Length up to 94 mm. (78 according to de Saussure). 



Locality. St. Thomas ( J£ Salle coll.) ; Santa Cruz {A. Newton) ; 

 Antigua. 



Dr. Karsch (Zeits. Naturwiss. (3) vi. pp. 8-9) has recorded 

 this species from Porto Eico. He characterizes two varieties of 

 it in the following terms : — Var. Krugii. " Black with reddish 

 border to the rings and reddish legs : western part of island." 

 Var. Gundlachi. " Greyish form, with dorsal red spot on the 

 rings and orange-coloured tarsi: centre of island and ? east coast." 



The colour of the typical form, of which the Museum has a 

 great number of alcohol-examples from St. Thomas, is usually a 

 greyish greenish black, the posterior third of the rings being 

 much darker and bordered with reddish ; the legs are greyish 

 green and concolorous. The specimens from Santa Cruz and 

 Antigua resemble those from St. Thomas. 



Some authors have suggested that this species is identical 

 with Bh. caudatus of Newport. There is, however, but little 

 resemblance between the two.
