pids, which had already hatched, or from which we bred no 

 imago. These would comprise some four or five species of Jas- 

 sids not mentioned in the foregoing account, the commn. 

 Tcttigonia albida, a Dcltoccphahis? a Phlcpsiusf and one or 

 more Bythoscopincs being among these. No doubt the para- 

 sites attached to some of these will prove to be different frotn 

 those here described, and yet many other new ones remain to 

 be discovered. 



SUPPLEMENTARY NOTE. 



After completing the above account of the Stylopidac and 

 sending it to press, it occurred to me that by sacrificing the few 

 male puparia that we preserved, mature pupae of the two 

 genera Mcgalcchthriis and Dcinclcnchus (which are character- 

 ized on females) might be obtained in such condition as to 

 allow some male characters to be determined. These puparia 

 were therefore opened and the contents examined; most of 

 them were empty, the male Stylopids having emerged, but in 

 two cases I obtained very immature and dried up pupae of 

 Megalechthrus. No details of structure could be made out 

 sufificiently accurately 'from these, but I believe the rudiments 

 of the antennae contained 7 joints, five being foliaceous, and 

 this would confirm its position in the Halictophaginae. 



From puparia of Dciiiclcirchiis T obtained no pupae, but in 

 one was a mature drv male of D. aiisfrolciisis, amplv confirmiup- 

 its position in the Elenchinae and the validity of the genus. I 

 here add the generic characters of the male, and a specific 

 description. 



Deinelenchus (male char.) 



Like Elencluis in most respects e. g. in the structure of the 

 tarsi and antennae, but very much larger, and with the secon;! 

 antennal joint, seen from above, very short and transverse, the 

 basal one elongate. Froiital process much blunter and less 

 prominent than in Elcncliiis. As in that genus, the face is 

 deeply excavated, but it is much more open, not triangular, but 

 with the sharp edge of the front and sides forming a great semi- 

 circle, or rather more. The palpi are two-jointed sparsely 

 pilose, the second joint narrower t'han the first and in the form 

 of a curved blade. The large size and wide excavation of the 

 face of this genus renders \\ much easier to examine structurally
