446 Mr. W. F. Kirby's descriptions of 



Scolia Alecto, Smith. 



Scolia Alecto, Smith, Proc. Linn. Soc, Zool., iii., p. 10 

 (1858). 



There is a male from Macassar, and a female from 

 Makian, in the British Museum. There is no doubt 

 that they belong to the same species, but the male is a 

 true Scolia (i.e., Triscolia), while the female is a Discolia, 

 thus proving that the two genera cannot be separated by 

 neuration alone. 



Scolia unimaculata, n. s. 



Long. Corp. 28 mm. ; exp. al. 45 mm. 



S . Black, clothed with black hair on the sides ; face thickly 

 punctured, a very strong frontal ridge, rising from the inside of 

 the eniargination of the eyes, and running below the ocelli ; the 

 space between this and the antennae is marked with very large and 

 deep punctures, but the vertex is nearly smooth, and the occiput 

 shows only a few small punctures. Thorax thickly punctured ; the 

 hinder half of the mesothorax smooth, except at the edges, and 

 there are smaller bare spaces. Abdomen shining black, with violet 

 reflections in a good light, the first three segments sparingly punc- 

 tured (except a line at the base of the second segment), and the 

 remainder very strongly. Under surface with the punctures more 

 distinct, especially those towards the base ; the first segment, and 

 the middle of the second towards the extremity, smooth ; the base 

 of the third with very minute and crowded but distinct punctures. 

 Wings strongly suffused with violet ; the rounded cell at the base 

 of the recurrent nervure (Burmeister's cell 5) yellowish subhyaline. 



Hah. India. 



Allied, not very closely, to S. Alecto, Smith. 



A specimen from Java differs in the darker purple 

 rather than violet colour of the wings, and in the much 

 more intense violet lustre of the abdomen. Until more 

 specimens are obtained it would be premature to regard 

 it as more than a variety. 



Scolia tyrianihina, n. s. (PL XV., fig. 2). 



Long. corp. 20 mm. ; exp. al. 33 mm. 



5 . Black, hair short, face strongly punctured, vertex smooth, 

 no frontal ridge ; thorax with very large punctures ; small bare 

 spaces in the middle of the mesothorax and on the inside of the 

 lateral lobes of the metathorax ; abdomen black, with violet
