37. Hypopus minutus Oudms., nov. sp. 



(With Plate III, fig. 55 and 56) 



Nympha. As nymphae of Hypopus have exactly the same fea- 

 tures as the adults, except that they have no genital apparatus, 

 I don't hesitate to describe this nympha and give it the above 

 name, by which 1 mean to say that even the adult must be a 

 miuute creature. 



Length 168 a*- Colour white, with straw-coloured hue, and white 

 legs. Stature robust, resembling that of Hypopus spinitarsus (Herm.) 

 {Rhizoglyphus echinopus (Fum. et Rob.)). On the dorsal side (Fig. 55) 

 the demarcation between the head and the thorax, and that be- 

 tween the thorax and the abdomen are clistinct. There are only 

 two cervical hairs, two posterior thoracal hairs, which are very 

 long, two shoulder-hairs, which are planted nearly midway between 

 the anterior and posterior margins, and three pair of marginal hair. 

 On the ventral side (Fig. 56) we observe the maxillae and the 

 palps, not remarkable for any particulars; the anus, nearly ter- 

 minal, flanked by two long hairs bent sideward and forward. 

 These hairs are characteristic. Legs. The legs 1 and 2 are much 

 stronger than 3 and 4, as in Hypopus spinitarsus (Herm.). The 

 tarsi 1 and 2 are provided with a little olfactoric hair; the tibiae 

 1 and 2 and the tarsi 3 and 4 with a tactile hair. 



Habitat: The creature was found by Prof. Dr. K. Kntjth, on 

 Xylocopa (Koptorthosoma) tenuiscapa Westw., in Dec. 1898 and 

 by Mr. S. A. Poppe on Vesperugo serotinus. 



Patria: Java, Germany.
