328 MR. HENRY WALTER BATES ON PHASMIDÆ. 
BACILLUS PATELLIFER. Femina, Cylindricus, robustus, granulatus, viridis ; antennis 
brevibus, filiformibus, articulo basali magno, ovato, complanato; capite postice at- 
tenuato, inermi ; femoribus anticis serratis, reliquis inermibus; segmento sexto ven- 
trali margine postico producto acuto; operculo usque ad apicem dorsalem protenso, 
angusto, vix convexo, obtuso.— Long. 4” 9" ; anten. 6° ; mesothor. 104”; metathor. 
81"; abdom. 2"-4-6""—2" 6”; ped. intermed. 1" 11" ; ped. post. 2” 9”, 
Allied to Bacillus cuniculus and B. Hyphereon (Westw. Cat. plate vi. figs. 1 & 2), but _ 
quite distinct from either. 
Body moderately thick, cylindrical, and covered throughout, closely and regularly, 
with small acute granulations, yet the integument is slightly shining: the colour light 
green. Head stout, moderately narrowed in a straight line behind the eyes, which are 
slightly prominent. Basal joint of antennz large, ovate, and flattened from base to apex, 
second joint also dilated, the rest filiform. Apical dorsal segment quadrate; sixth 
ventral segment with the hind margin produced and acute in the middle; operculum 
reaching the tip of the abdomen, obtuse, narrow, and scarcely convex ; anal styles short, 
filiform, pointed. Legs moderately stout, ridges of middle and hind femora with a few 
minute spines, upper and lower ridges of anterior pair strongly serrated. Tarsi simple.

BACILLUS SCYTALE, n.sp. B. cylindricus, elongatus, levis, luteus; capite oblongo, pos- 
tice attenuato, inermi, linea transversa inter oculos elevata; oculis prominentibus; 
antennis articulo basali magno dilatato; abdomine segmento dorsali terminali apice 
medio inciso, angulis apicalibus distinctis; pedibus validis, modice elongatis, 
femoribus anticis supra serratis, intermediis posticisque apice infra unidentatis, 
tibiis quatuor posticis apices versus serratis (fem.).—Long. corp. 6” ; mesothor. 16”; 
metathor. 12”; abdom. 3" 1". (Plate XLIV. f. 9.) 
Agrees in size, form, and armature of the legs with B. cuniculus (Westw.), but differs 
in wanting the cephalic horns which distinguish that species. 
Head oblong, narrowed behind, unarmed, but with an obtuse, thick- transverse ridge 
between the eyes; basal joint of antennæ dilated and flattened (broken beyond the 
fourteenth joint). Thorax eylindrical and smooth. Abdomen smooth; seventh dorsal 
segment two-thirds the length of the sixth; eighth little more than half the length of 
the seventh, and considerably shorter than the terminal segment; the latter with the 
apical edge notched in the middle and with the lateral angles distinct ; operculum (2) 
reaching the extremity of the abdomen, inflated and keeled towards the tip; anal sty les 
erately elongated, intermediate pair short; ante- 
four posterior tibiæ with the raised lines towards the apex 
finely serrated; basal joint of the tarsi about the same length as the three following 
joints taken together. 
Hab. Ceylon : Coll. Nietner, This species, with several othe 
flattened basal joint), will range under the 
Bacillus (Ramulus) Humberti of this auth 
rs having a similar form of antenne (largo 
genus Ramulus of M. de Saussure ; it is closely allied to 
or (Annales d. 1. Soc. Entom. de France, 1861, p“ 479)
