Mr. A. AVhite on Myriapoda of the ymua Zepbrouia. -405 



with seven-jointed antennae, in which the sixth or penultimate 

 joint is oblong: generally, a little longer than the fifth, the last 

 the least of all, and truncated at the tip ; while in Sphceropicus 

 the antennse are six-jointed, the penultimate is short, and tbe 

 last is the largest, is oblong, and is rounded at the tip. My 

 friend Professor Gervais* has judiciously (so I think) reduced 

 these two genera of the able Russian naturalist into one, retain- 

 ing Dr. Gray's excellent name of Zephronia. 



]. Zephronia Adceon, n. s. PI. VII. figs. 5, 5 « & 5 6. 



Z. gigantea, nitida, polita, livido-flava ; capita postice et inter oculos 

 sparsissinie punctate, antice plus punctulato ; segmentis puncta- 

 tissimis, punctis fere coufluentibus, niarginibus posticis Isevibus 

 subpunctulatis ; segmentis 8, 9, 10 et undecimo lateribus abrupte 

 sectis. 



Hab. Madagascar (Madame Ida Pfeiffer). 



This comes near Zephronia hippocastanum, Gervais (/. c. 83) ; 

 the last ring of the abdomen has on the side, at the base, a slight 

 notch, or rather the basal edge projects beyond the general 

 margin ; the nuchal plate is very smooth and has scarcely any 

 punctures; the front margin is only shghtly waved; the eyes of 

 each group are closer on the inner part of the squarish mass, 

 into which they are accumulated. 



2. Zephronia (Sphserop.) pulverea, u. s. PI. VII. figs. 4, 4 r/, & 4 b. 

 Z. obscure fusco-pulverea, linea dorsali medianaiuterrupta, Isevissima ; 



segmentis crusta, terrse pulveri simili, densissime tectis, segmento 

 apicali postice lobato-angulato, Isevissimo, et cavato. 

 Hab. in Afr. mer. (Port Natal). 



Head and cervical plate shining, smooth, deeply and irregu- 

 larly punctured ; head between the eyes with two longitudinal 

 depressions ; eyes granularly beaded like mulberries. 



Last segment smooth and polished, except at the base, where 

 it is dull and pulverose, hollowed behind ; edge somewhat waved 

 on each side, behind roundly lobed. 



This species is allied to Z. dorsalis, Gervais, /. c. p. 79. 



3. Zephronia (Sphserop.) versicolor, n.s. PL VII. figs.3, 3a, & 36. 

 Z. Isevis, nitida, lutea, nigro irregulariter plagiata et maculata ; oculis, 



antenuis pedibusque (in mortuis exemplis) pallide viridibus ; capitis 

 segmento uuchali lateribus acuminatis, antice medio sublobato. 

 Hab. Ceylon. 



This species may be known by its luteous-yellow colour, 

 blotched and spotted with black, each specimen varying in mark- 

 ing; the head, on the face, is punctured with distant points,
