ducts of each gland (sd and rd) join on Ihe gland ilself and open 



into it by an exceedingly short common duct (sjd, lig. 3). The sali- 



vary-duct runs from each gland anteriorly along ihe lloof of Ihe 



head-capside (hc) lo Ihe 

 syringe (s) where it joins 

 its fellow duct on the under- 

 side of the syringe itself. 

 The réservoir duct (rd) also 

 runs up into tlic head, being 

 caught up i»y muscles and 

 Iracheae there (d, tig. 3) ; 

 making a very sliarp bend 

 over thèse muscles etc. it 

 returns ont ufthe head and 

 runs down to the llattened, 

 saccular salivary- réservoir 

 (sr) whicli lies against the 

 side of the anterior part of 

 the stomach. The duct 

 enters the réservoir dor- 

 sally, The accessory-lube 

 (at) of the réservoir ai'ises 



from the side thereof and lies laterally and dorsally — and more 



or less coiled — over the posterior part of the slomacli, lo w liich 



both it and the réservoir are attached by iiuuierous raniilicalions 



of fine trachéal tubes. The réservoirs are innervatcd by Iwo nerve- 



cords (n) which follow the reservoir-ducts 



down from the sub-œsophageal ganglion. 



AU the salivary ducts are nucleated ami \^z 



are marked transversely somewhat like 



trachéal tubes (e, fig. 3). 



In Enectus elongatus (1), as shown at 



fig. 4, the ducts of the réservoirs are zig-zag 



or ladder-like : the whole of this part is 



rather chitinous, wiry and elastic, and of 



great length when straightened out : the 



lumen of the duct is also narrow and the 



walls thick. The ducts are caught up by 



muscles and tracheae within tlie head (as in 



the former Bug), bend sharply and return 



to the réservoirs (sr) whicli in this instance 



are simple tubes. The upper part of each salivary-gland is bilobed, 



il) Tliis was desciibed as a new species l)y Mr. W. L. Distant in the « Auu. 

 aud Mag. of Nat. Hist. » for Oct. l'JlO, where he notes that it was the tirst of 

 that ereuus recorded from Australia.
