KOEBELIIDJE 

 The genus Koebelia with the species calif ornica, was described 

 by me twenty-five years ago for a very peculiar and isolated 

 western American type, for which I suggested the family name 

 Koebeliidze. 13 At that time I possessed specimens of both Ulopa 

 and Paropia, but did not realize their relationship, since the 

 facial characters seemed to be very distinct from either. Not 

 until material of Stenocotis came to hand did the relationship 

 appear clear, the genus lying between Stenocotis and Ulopa, 

 though very distinct from either (Plate 1, fig. 3, a). VanDuzee 

 lists the genus under the "Paropiinse," synonymizing Koebe- 

 liidae with this subfamily. This is an entirely erroneous dispo- 

 sition of it, since it is far more closely related to Ulopida- than 

 to Paropiidse. Moreover, the characters which separate it are 

 entirely equivalent in value to those of the other families of this 

 series. The strong dissimilarity between it and either Ulopa or 

 Paropia is evident in important facial characters (Plate 1, fig. 3, 

 a) . However, its intermediate position between Ulopa and Paro- 

 pia on the one hand and the Stenocotidae sens. str. on the other 

 is also indicated by comparison of the figures of Koebelia and 

 Kyphocotis tessellata Kirkaldy (Plate 1, fig. 2, b). 

 SIGNORETIID^E 

 In my first paper on this group it was quite by chance that the 

 two species of Signoretia treated represented two natural div- 

 isions of the genus, one with a short swollen declivous head, the 

 other with a longer, less-swollen head, held in the long axis of 

 the body. The collection of abundant material of true S. ma- 

 laya Stal, at Singapore, enables me to identify certainly S. ma- 

 laya of my former paper as merely a geographical form of it. 

 In his descriptions Distant gives no specific structural characters 

 for the two apparently very distinct species S. aureola Distant 

 and S. greeni Distant, so that it is impossible to judge of their 

 relationships. Characteristic of this family are the very small 

 and short loree.
