Gen. Gyiia Br. 



Gyna retula Br. 

 Gyna vetula Brunner v. Wattenwyl, Nouv. Syst. des Blatt, p. 267 (1865). 



In the MkiJumusi-caves at Tanga (July), 1 cT, 1 ?, 17 larvae. 



Previously recorded from Mombasa (von der Decken) and the East coast of 

 Africa. 



It seenis quite certain that the genera Trichomera Kirby^ and Apotrogia Kirby^ 

 are founded on immature specimens of species of Gyna. Tlie larvae collected by Dr. 

 Sjöstedt are certainly most closely alhed to Trichomera insignata Kirby; they are 

 preserved in alcohol together with one adult male in bad condition and were probably 

 taken altogether from under one shelter. The backwardly produced angles of the 

 meso- and metanotum proclaim the immature condition of these specimens as well as 

 of T. insignata Kirby and Apotrogia angolensis Kirby. I find moreover that the 

 structiire of the maxillarv and labial palpi, the form of the coxae and the arrange- 

 ment of speines on the tibiae is identical in the larvae and adults. The palpi in tlie 

 genus Gyna are highly cliaracteristic, being very slender and ratlier long, and the 

 coxae are provided with a peculiar ciirved f lange, situated on the outer posterior 

 angle ; the front tibiae in the larvae are shorter than they are in the adults, but this 

 feature is probably associated with fossorial habits, abandoned when the insects become 

 Avinged adults. The arolium between the tarsal claws does not develop until the 

 larvae are nearly full-grown and it is then smaller than in the adult. The pronotum 

 is far less backwardly produced in the larvae than in the adults, as is also the case with 

 larval Epilamprides, larvae of Panchlora and of Rhyparobia. Finally the larvae are 

 much more heavily marked with castaneous than are the adults and there are rows 

 of minute tubercles on the dorsal tergites.
