chamberlin: west Indian chilopoda and diplopoda. 169 



First flagelliim of antenna with about seventy articles which are 

 long. Total number in the second division uncertain. First joint 

 of first tarsal division of legs very long. First tarsal division of fourth 

 legs with nineteen joints; first division of eighth legs in type with 

 but twelve joints. 



Stoma saddles strongly elevated. Caudal margins of ordinary 

 tergites mesally moderately emarginate. Last tergite with caudal 

 end conversely rounded, not at all incurved as in P. cuhensis and P. 

 pidchrifarsis. 



Length near 36 mm. 



58. PSELLIOPHORA MINOR, Sp. nOV. 



Type. — M. C. Z. 1,887. Cuba: Guantanamo, San Carlos Estate, 

 April 22, 1914. C. T. Ramsden. 



This small species resembles P. cuhensis, of which I at first suspected 

 it of being the young, in having the median pale stripe covered ex- 

 cepting in a narrow line at each side by an enclosed dark stripe though 

 the latter is deeper and more strongly marked than in the other 

 species; on the head it has the characteristic form as in P. cuhensis. 

 The lateral edges of the tergites are pale, the light stripe very narrow 

 and sharply limited and extending also along caudal margin. The 

 dark bands deep chocolate colored. The coloration is strikingly 

 different from that of P. cuhensis in the case of the legs which are 

 strongly marked with dark. The cross bars or annuli of femur and 

 prefemur more or less confluent above, incomplete ventrally and more 

 obviously separated. Tibia darkened in longitudinal stripes except 

 for a conspicuous annulus at distal end which is bright whitish. 



L'nlike P. cuhensis the last tergite is not posteriorly incurved but on 

 the contrary is strongly obtusely produced, with the apex rounded. 



Articles of first division of antenna about forty-eight, of the second 

 one hundred and sixty or above. The articles in large part are ex- 

 ceptionally short, approaching the proportions of Scutigera. 



The first division of the tarsus of the ninth legs is composed of only 

 seven segments, the second of twenty-eight. 



Length about 12.5 mm.
