gradually larger to the tiftli. whitli is largest and tlien becoming; gradually 

 smaller to the last (tenth) which is smallest. The second and third segments 

 each have nn the under side a i)air ol' narrow slit-< close to the median line- 

 (^=stigmata probably). 



The abdomen is (|uite regularly oval in shape, very sliglitiy depressed, of 

 a general ashy coloi, with a yellowish tinge: two rows of dark brown sub- 

 quadrate spots form two stripes along the dorsal surface, commencing on the 

 second thoracic segment and extending separately to the eighth segment. 

 On the ninth and tenth segments the two spots are united into one. These 

 dark stripes are al.so faintly visible on the underside of the last tiiree seg- 

 ments. On tlie underside is a median and two lateral faintly depressed lines. 

 Tlie al)d(mien i^ clothed very sparely with very fine hairs: iiairs are more 

 numerous on tlie dark spots above: anus, a vertical slit, closed by two smooth 

 lips on tenth segment. 



Colors: cephalic shield, mandibles, ma.xilla, labia and first two movable 

 joints of ma.xillary palpi and labial palpi, basal and coxal and trochantal 

 joints of all the legs and base of femur, ochre yellow, fawn color, flesh color. 

 The abdomen yellowish, ashen gray, lighter l)el<jw. The terminal i)ortion 

 of the femora, tlie whole of the tib);e. all of tiie metatarsi, except tlie ti|)s., 

 tlie third, fourth and fifth movable joints of the maxillary and labial palpi, 

 and the two stripes on the abdomen, dee]), ilark lirown: the lal)ial palpi be- 

 ing rather ligliter: the tarsi rather |)aier in i-oi<»r: tlie jaws reddish, pa.ssing 

 into black at tlie tips and the teeth. 



Eyes round, gray, encircled with iilack : labial jialjii very weak and slen- 

 der. Maxillary palpi very stout. Lingua as in figure. 



This (Icscriptiun is inustly made up from the specimen collecteil 

 bv Di-. Wm. Stimpsoii. The specimen collected by Mr. AVurdonian, 

 is in Ijetter condition; the abdomen larger, (fnll of eggs?) briglitr-r 

 and deeper colored throurrhout. It was evidently in a state of ex- 

 citement when '-aptuied. The llesiiv organ at the end of the right 

 maxillary palpus is extruded, while that on the left is withdrawn. 

 The riglit labial palpus has Ijeen canghl in the jaws. In the Wuv- 

 denian specimen the outer tooth of the lower jaw is a little sharper 

 than in Stimpson's, otherwise the dentition is ahk*-.
