THE MYRIAPODA OF NORTH AMERICA. 87 



tinet, about 10, arranged in 3 transverse series. Segments 47. Antennae 

 and legs stouter. 



The above notes are based on a dried female, which was afterwards 

 soaked in alcohol. As this is the first record of a species of this genus 

 from Cuba, I have given it the specific name of cubensis. 



3. Paradesmus poeyi Bollman. Strongylosoma poeyi Bollman, Eur. Amer., 82, 1887 

 (Cuba). 



Abundant. 



Through a misunderstanding of the description of Paraiesmus I 

 placed this species in Strongylosoma, and did not discover my mistake 

 until after the description of the above species had been published. 



This species should now be placed in the genus Paradesmus. It is 

 very closely related to, if not identical with, P. ricarius Karseh, from 

 Mayotti and Anjaani. 



The copulation foot of the males of poeyi differs from that of viearius, 

 as figured by Karseh, in having the femoral part twice as long as the 

 tibial, and the lower lobe of the tibial part is wide and thin, with a dis- 

 tinct median thickening, not cylindrical as in vicarius. 



4. Leptodesmus couloni. Polydesmus (Oxyurus) couloni Humbert & Saussure, 

 Myr. Nov. amer., 3, 1869 (Cuba). 



Among the material sent by Poey is a dried female, which agrees 

 perfectly with the descriptions of the above species. 



5. Stenonia maculata. sp. nov. 



Diagnosis. — Related to Stenonia fimbriata (Peters), but at once sep- 

 arated by the tuberculation of the dorsal plates, by the cienulation of 

 lateral carina', by the character of anal segment and the pattern of col- 

 oration. 



The following is a careful description of the species: Rosy, especially 

 the tubercles; nearly all the repugnatorial pore bearing segments with 

 a deep blotch on each side above the carinse ; antennae dark, legs pale. 

 Body wide, convex, not attenuated anteriorly, slightly posteriorly. An- 

 tenme short, subclavate. First segment very wide, completely conceal- 

 ing the head as in fimbriatus ; a row of small scales along the posterior 

 margin; two large median scales; along anterior margin a row of 

 twelve rectangular scales, between the third and fourth from posterior 

 angle a distinct notch, between the others a slight waviness. Other 

 segments with three distinct rows of scales with smaller ones inter- 

 spersed; lateral carina* crenulate the first six, the eighth, eleventh, and 

 fourteenth, with two crenulations, the rest with three; a distinct me- 

 dian dorsal line. Anal segment with six tubercles along posterior 

 margin; preanal scale obtuse, with two loug, slender spines. 



Length, £9 mm , 9 12.5"""; width, 6 2.2 mm , 9 2.8 mm . 



This new species belongs to the subgenus Stenonia ( = Plati/rhaeus). 



Among the material sent by Prof. Poey is a dried male and female of 

 this species.
