striated. The mesothorax with a few longitudinal dark lines; the scutellum convex, and 
rounded behind; the metathorax truncate, not spined, and paler than the mesothorax; 
wings clear hyaline, the nervures and stigma pale rufo-testaceous. Abdomen ohlong-ovate, 
the base castaneo-rufous, from thence becoming gradually darker to the apex. Eemale, 
length 31 lines. 
Sab. —Jhilam valley, Punjab hills. Taken in July. 
34. Eobtlus (Typhlopone) l^viceps, Pig. 2. 
Operaria.— T. rufo-testaceus, Ga,pite castaneo, mandihuUs nigris. 
Head - oblong, subquadrate, rather wider anteriorly, the flagellum slightly fuscous; 
very smooth and shining, and with a very faintly impressed central longitudinal line, 
and also a few delicate scattered punctures. Thorax oblong, divided in the middle by a 
transverse suture, flattened above and having a few fine punctures. Abdomen, the node of 
the peduncle incrassate, subquadrate above; oblong-ovate. Worker, length lines. 
Sab. —Jhilam valley. Taken in July. 
The insects described under the generic name Typlilopone of Westwood are now dis¬ 
covered to be the workers of Dorylus ; the late Dr. Jerdon observed them issuing from the 
nests, in company with males of Dorylus; Dr. Gerstaecker has described the female of 
Dorylus in the Stett. Ent. Zeits. for 1863, under the generic name DicMhadia^ pointing out 
its affinities of structure with those of the male, upon which the genus was founded; and 
proving demonstratively the affinities of the genera. 
35. Mutilla stjspiciosa. 
Midilla suspiciosa, Smith, Journ. Proc. Linn. Soc., II, 84 $ (1867). 
Sab. —Jhilam valley. Taken in July. 
This species resembles the male of M. sexmaculata, but it differs from it by having the 
wings entirely dark brownish-black; the abdomen is red, with the base and apex black; it 
has been found in Borneo, Batchian, Celebes, Amboyna, and Bourn. 
36. Mtjtilla sexmaculata, Swederus. 
Eemina.— M. nigra^ thoraoe supra rufo, abdomine utrinque serie trium macularum 
alhidarum. 
Mas.— M. nigra, thoraoe antioe cinereo, abdomine rufo, basi nigro, alis fuscis basi 
hyalinis. 
The male of this species was discovered by Sir John Hearsay, who captured the sexes in 
coitu; it, as well as the female, varies greatly in size. I suspect it is the Mutilla rufogastra 
of St. Eargeau. 
M. Badoszkovsky, in his Monograph of the Mutillid(B of the Old World, says that 
the insect I have named M. sexmaculata of Swederus is not that species; I have care¬ 
fully compared the insect with the descriptions given both by Swederus and by M. 
Badoszkovsky, and am quite satisfied that my quotation is correct, although it is said by
