Family ORYID^. 
1. Orphn^us phosphoreus (Linnseus). According to Pocock there is but 
one species of Orphnseus in spite of the several synonyms, and I am in- 
clined to this view after having examined material from the Malaysia, 
Aldabra Islands, Liberia, and "Rrazil. There is some variation in color- 
ing, but this is not constant, and depends somewhat on methods of 
preservation. Dried specimens frequently become purple, as was the 
case with the type of Linnseus. In Liberia it appears that Orphnseus 
lives only in civilized houses, and has doubtless been imported. It is 
moreover found only in the dry wood which has been riddled by term- 
ites, which probably form the chief food of this species, and would ac- 
cordingly be readily carried in shipping, which explains the remarkable 
phenomenon related by Linnseus. At Sierra Leone a specimen ap- 
peared quite as mysteriously upon the deck of our steamer. Moreover,' 
the other characters given by Linnseus do apply to many dried speci- 
mens, and if there is but one species of Orphnseus it may with consid- 
erable safety be called O. phosphoreus. 
2. Pentorya afra Cook. In the preceding paper were given reasons for 
doubt of Porat’s determination of Himantarium. fusatum C. L. Koch 
from Kamerun, and the above new name was given rather than to con- 
tinue a false reference in the literature. 
IS Cook. Color in life fuliginous, or violaceous, or 
black, sometimes fading to yellowish in alcohol. Antennse with last joint 
equaling the two preceding ; basal lamina abqut three times as broad as 
long ; mandibles with one dentate and^.one (or two ?) pectinate lamellse, 
each many-toothed; sterna bisulcate^ roughened and hirsute; pleurss 
of last segment moderately enlarged and .pilose, the two large pores 
concealed under the hirsute last sternum which is broader than long 
(8:5); anal legs densely hirsute; pairs of legs 63-73. 'Phis species is 
very rare, and after much careful searching I succeeded fin bringing 
home only about a dozen specimens. In the Berlin Museum are several 
examples from Togo of a form somewhat more slender and lighter 
colored than B . clavicoruis, but I have found no characters sfficient to 
distinguish it specifically. 
4. Ballophilus maculosus (Porat). There can be little doubt, that Porat’s 
Geophilus maculosus belongs in the present genus, and the presence of 
B. clavicornis at Togo suggests that the two species may be the same, 
but in that case Porat has overlooked the vef^: large pleural pores. Be- 
sides, none of the Liberian or Togo specimens has more than 73 seg- 
ments, while B. maculosus is c^dited w 4 th 77.

5. Ctenophilus africanus Cook. Bright pink in life, pale yellowish brown in 
alcohol, the head darker. Prehensors slightly surpassing the frontal mar- 
gin of the head ; sternum longer than the coxa (3:2), narrowly emargi- 
nate anteriorly ; coxa wuth a rudimentary subapical tooth ; ventral
