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 oblong-ovate, 
the base castaneo-rufous, from thence becoming gradually darker to the apex Pemale 
length 3| lines. 1 ‘ ’ 
Sab. — Jliilam valley, Punjab hills. Taken in July. 
34. Dorylus (Typhlopone) l^eviceps, Pig. 2. 
Operaria, — T. rufo-testaceus, capite castaneo, mandibulis nigris. 
Head 1 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 3 J lines. 
Sab. — Jhilam valley. Taken in July. 
The insects described under the generic name Typhlopone 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 Dichthadia, 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. Mtttilla suspiciosa. 
Mutilla suspiciosa, Smith, Joum. Proe. Linn. Soc., II, 84 $ (1857). 
Sab. — Jhilam valley. Taken in July. 
This species resembles the male of If. 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, Batcliian, Celebes, Amboyna, and Bouru. 
36. Mutilla sexmaculata, Swederus. 
Pemina. — If. nigra, thorace supra rufo, abdomine utrinque serie trium macularum 
albidarwm. 
Mas. — If. nigra, tliorace antice cinereo, abdomine rufo, basi nigro, alls fuscis basi 
hyalinis. 
The male of this species was discovered by Sir John Hearsay, who captured the sexes in 
eoitu ; it, as well as the female, varies greatly in size. I suspect it is the Mutilla rufogastra 
of St. Pargeau. 
M. Badoszkovsky, in his Monograph of the Mutillidce 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. 
Radoszkovsky, and am quite satisfied that my quotation is correct, although it is said by
