The fossils dealt with in this Part belong to the third collec- 

 tion of fossil Insects from the Upper Trias of Ipswich, Queens- 

 land, already referred to in No. 3 of this series ($, p. 4 17). In 

 No. 1 of this series (3) I dealt with the Planipennia, Trichoptera, 

 and Protomecoptera from the second collection made by Mr. 

 Dunstan (if we count in also the Simmonds collection, this would 

 he the third collection made at Ipswich altogether). As the new 

 insects throw much light upon the important Orders which they 

 represent, it seemed best to deal with them as soon as possible, 

 even though many other fossils from the earlier collections still 

 remain undescribed. 



The material dealt with consists of two Mecoptera, two Tri- 

 chopterous-like insects, one Planipennian, and one wing of un- 

 certain position within the Panorpoid Orders. The Mecoptera 

 are not well preserved, and one is too fragmentary to merit a 

 name. The Planipennian, though not a complete wing, is one of 

 the most beautifully preserved and most important of the new 

 types found at Ipswich. One of the Trichopterous-like fossils is 

 an almost complete and very beautifully preserved forewing, 

 showing some quite new and unexpected characters, which prove 

 that the wings from the Ipswich Trias which we have hitherto 

 regarded as true Trichoptera, do not really belong to that Order, 

 but to a distinct group separated from it by two very important 

 characters. My original intention was to place these within a
