pharynx originates on each side an oblong, triangular i)rocess, 

 lying partly outside of, partly (seen from below) somewhat beneath 

 the basal part of the hypopharynx). This process (m) is a little 

 longer but considerably narrower than the hypopharynx, soft- 

 skinned, with exception of the outer portion of the side turned 

 downwards. These two processes are generally described as para- 

 glossa, but this name is extremely infortunate, because they have 

 nothing to do neither with tlie hypopharynx nor with the labium; 

 as I have stated in »Zool. Anzeiger» (see later on) they must 

 be considered as the reduced Jiiaxillulœ, homologous with the 

 ist pair of maxillœ in Cnistacca (which 1 have called inaxillulce) 

 and that these organs are found much higher developed like real 

 maxillul^e in JSIachilis and especially in Cavipodea and Japyx. 



The upper side of the hypopharynx is posteriorly the con- 

 tinuation of the inferior wall of the pharynx, and at the beginning 

 of the latter is found just behind the hypopharynx on each side 

 a 3-branched chitinous plate (^Pl. 2, tig. 10), the one branch of 

 which (n) is directed behind, being long and broad and at the 

 middle ornated with a small group of very small sense-pits (s), 

 most likely organs of taste; the second branch is directed out- 

 wards, the third (o) is slender, curved, directed inwards and a 

 little forward and in the median line coalesced with the corres- 

 ponding branch from the opposite side ; in front of this thuswise 

 formed arch is seen another slender transverse arch (p), the ends 

 of which come in contact Avith the anterior margin of the first- 

 mentioned arch a short way from its beginning. 



c. Thorax. Both on the prothorax and on the mesothorax 

 the terga are strongly expanded at the sides, forming free, rather 

 broad, somewhat deflexed plates, further the posteriorly strongly 

 emarginated pronotum overlaps a considerable part of the meso- 

 notum, and this, posteriorly somewhat lesser emai\ginate, overlaps 

 a portion of the metanotum. The metanotum is considerably 

 shorter and somewhat narrower than the mesonotum, while the 

 pronotum is almost as long as the two other nota together and 

 but very little narrower than the mesonotum. When the thorax 

 is seen from below (Pi. 3, fig. i) the free lateral tergal plates of 

 the pro-and mesothorax (a and b) are very conspicuous; the sterna 

 are strongly developed in all 3 segments, forming large median
