﻿94 ENTOMOLüGISK TIDSKRIFT I919. 



Family Boopiidas M.iöB, 



During my expeditions to Australia, I brought together 

 a collection of Mallophaga, which owing to lock of time not 

 have been worked up yet. Among those are also some mem- 

 bers of the above mentioned family, which apparently re- 

 present new genera and species. The will be more com- 

 pletely described by the author in »Results of Dr. E. Mjö- 

 bergs Swedish Scientific Expeditions to Australia 1910- — 1913». 



Dendrolagia n. g. 



Hetcrodoxus-\\Vç. forms with the temporal lobes of 

 head well set oft" as in the genus Boopia PlAG, with two 

 very strong, dagger-like spines beneath head, rising im- 

 mediately behind the palpi, prothorax broader and not so 

 long as in Boopia, winged and more rounded at the sides; 

 metathorax slightly tapering on the sides to the front margin, 

 but not producted at the posterior angles; proand mesothorax 

 with tzvo fairly short, strong chitinous spines between the 

 coxae. Last dorsal segment in Ç ending in two very sharply 

 pointed processes which are more strongly chitinized at the 

 sides and finely crenulated at the inner margin. 



Dendrolagia pygidialis n. sp. 



Body smaller, more slender and more lightly colour- 

 ed than in Heterodoxiis lo7igitarsus PlAG: dorsal occipital 

 margin with two chitinous spines and with strong chitinous 

 hairs; mesothorax emarginate at the front margin; dorsal seg- 

 ments of abdomen with a row of 8 hairs' and darker chiti- 

 nous crossband. Length ^ 2,38 mm. $ 2,49 mm. — Found 

 in large number on Dendrolagus Liwiholtsi COLL. from Ma- 

 landa and Cedar creek, N. Queensland. 



I have named this genus after the peculiar marsupial- 

 genus on which it is to be found. It is'^very probable that 

 more species of this genus will be found on the New Guin- 

 ean DendroIaguss^Qc'xes.
