mencing from the rostral end, a comparatively large 

 shield-shape plate in the median line ; a curved, more 

 or less triangular plate on each side of and partly be- 

 hind it ; then a transverse row of about five smaller 

 round or oval plates ; lastly, still further back and close 

 to the abdomen, a second transverse row of about eight 

 plates, of which the two outer are the largest, and are 

 usually oval ; the next pair are smaller and of the so- 

 called pine-shape common on Indian textile fabrics; 

 the two inner pairs are very small and round. Abdomen 

 almost square, except that the hind margin is cut into 

 four rounded lobes, of which the central pair are the 

 larger, and consequently project further backward. 

 Above these two central lobes, and a little further for- 

 ward, are two large conical papillae, or apophyses, 

 directed upward and backward. In front of the 

 papillae is a transverse ridge with the ends turned 

 forward ; bearing two large, rough hairs. The noto- 

 gaster is nearly, but not quite flat; the central part 

 being slightly arched and divided by a narrow and 

 shallow depression from the slightly raised and rounded 

 edge ; which is also rather lobed both at the anterior 

 and posterior ends. The notogaster bears a number of 

 plates of a similar nature to those on the cephalo- 

 thorax ; the forms and arrangement of these plates are 

 usually somewhat as follows : viz. two longitudinal 

 rows, each of about four pine-shaped plates, on the 

 arched central portion ; on each lateral border, proceed- 

 ing from the anterior toward the posterior end, firstly 

 two pine-shaped plates turned different ways, then two 

 small roundish plates followed by two more pine-shaped 

 plates, and finally a single large, irregular- shaped 

 plate. There are three pairs of broad, spatulate hairs, 

 or scales, on the hind margin ; and one pair on the 

 antero -lateral angles. Legs of moderate length, the 

 fourth pair not reaching the hind margin, thinnish ; 

 coxae rather large; other joints of about even thick- 

 ness throughout, except the tarsi, which diminish 

 gradually. There are the usual tactile hairs on the
