at all clear that the minute knot he considered the third joint is 



more than the articulation 

 V \ of the elongate terminal 

 /"^ joint. The family consists 

 only of two or three species 

 of Aglycyderes, one of which 

 occurs in the Canary 

 Islands, and one or two in 

 ISTew Zealand and New 

 Caledonia. The former is 

 believed to live in the stems 

 of Euphorhia canariensis ; 

 a Xew Zealand species has 

 been found in connection 

 with the tree-fern Cyailiea 

 de/ilhr/ta. 

 Fam. 85. Proterhinidae. — Tarsi tliree-jointed, the second joint 

 lohed ; head of the male scarcely prolonged, but that of the female 

 forming a definite rostrum.; onaxillae and liguhi entirely covered 

 ly the mentum. As in the preced- 

 ing family the sutures on the 

 under side of the head and pro- 

 sternum cannot be detected. The 

 minute palpi are entirely enclosed 

 in the buccal cavity. There is a 

 very minute true third joint of 

 the tarsus, at the base of the ter- 

 minal joint, concealed between the 

 lobes of the second joint. The 

 family consists of the genus Pro- 

 terhinus ; it is confined to 

 Hawaiian Islands, where these In- 

 sects live on dead wood in the 

 native forests. The genus is numerous in species and individuals. 

 Strepsiptera (or Rhipiptera, Stylopidae). — Male small or 

 minute; prothorax extremely small; mesothorax moderate, the elytra 

 reduced to small, free slipis ; rnetathorax and wings very large; 

 nervuration of the latter radiating, v:ithout cross nervules. Female 

 a mere sew, with one extremity smaller and forming a sort of neck 

 or head. These curious Insects are parasitic in the interior of 



the Fig. 152. — Pmterhinus hmntei. Ha-
