A New Diplopod from British Guiana taken at 

 Quarantine at Philadelphia. 



I'.y RALPH V. CHAMBERLIN, Cambridge, Massachusetts. 

 A number of myriopods were found in soil around a potted 

 palm from Georgetown, British Guiana, by Inspector Chester 

 A. Davis who took the plant from a passenger on the American 

 schooner "Rosalie Hall" at Philadelphia on May 23, 1921. 

 Among these are two specimens of the chilopod Me cist o- 

 ccphalns iiui.villaris (Gervais) which, it may be noted, was 

 first described at Paris in 1837 from a specimen apparently 

 similarly immigrant. One symphylid occurs, this being the 

 widespread Scutigerella innuaculata (Newport). The diplo- 

 pods represented comprise a female of the tropicopolitan 

 Orthonwrpha coarctafa (Saussure), two very young spirobo- 

 loids probably belonging to Rhinocricns, and the interesting 

 new nannolenid described below, this being represented In 

 several males and females. 



TRICHONANNOLENE, gen. nov. 



Gnathochilarium as in Epinannolenc. Ocelli present. Head 

 and tergites clothed with numerous short hairs. Gonopods of 

 male with telopodite presenting a slender branch octal in posi- 

 tion and fitting into a notch of the principal branch: the latter 

 broad, not two-pronged as in Epmannolene. Posterior legs of 

 seventh segment in male abortive. Genotype, T. (juiiuiaims, 

 sp. no\ . 



Trichonannolene guiananus, sp. nov. 



Dark brown, with head, antennae and legs paler. 



Head proportionately broad; with no distinct median sulcus across ver- 

 tex; clothed with numerous short, straight hairs. Antennae with second 

 aiticle narrower than the first, slender and widening distad, the other 

 joints widening clavately distad to the fifth, the sixth cylindrical, the 

 seventh short and narrower. Hyes widely separated; composed of com- 

 paratively few, small and often indistinct, ocelli which are normally in 

 two series or with one in a third; e. g., 2. 4; ,\ .1; .1. 4; and 1. 3, 2. 



Col him with caudal margin nearly straight, the anterior margin con- 

 vex ; lower ends indexed beneath, rather narrowly rounded, the anterior 

 margin flattened or slightly notched a little above the lower end; with 

 four principal striae beneath on each side, these striae line and curving' 

 upward anteriorly so as to parallel anterior margin for a short distance. 

 With numerous regularly spaced ^etae similar to those of head.
