A NEW SPECIES OF EURYTOMA FROM QUEENSLAND. 53 



and mexicana, Crawford, by having two spines at the hind angle 

 of the prothorax, and from both manicatus, Bagnall, and similis, 

 Bagnall (if these two are really distinct and not forms of 

 the same variable species), by the more slender antennse and 

 relatively longer prothorax.

A NEW SPECIES OF EURYTOMA FEOM QUEENS- 

 LAND, WHICH LIVES IN THE STEMS OF 

 EUCALYPTUS. 



By a. a. Girault. 



The following species seems phytophagous, since I found it 

 inhabiting short grooves or channels under the bark of young 

 Eucalyptus trees, somewhat after the manner of Scolytidse. 

 Where occurring, the stems of the trees were somewhat swollen. 

 When one thinks of it, this species does not seem to differ greatly 

 in habit from the other members of its tribe, which seem to live 

 on galls rather than upon gall-makers. Has the parasitic habit 

 of the Eurytomini been proved ? The genus Bruchophagus would 

 incline one to doubt. 



Genus Eurytoma, Illiger. 

 Eurytoma picus, n. sp. 



Black, the legs, tegulae and scape rich reddish brown, the hind 

 coxge black, the wings hyaUne; flagellum brownish yellow, knees 

 and tips of tibiae yellow. Propodeum with a rather broad median 

 groove. Venation pale ; postmarginal and stigmal veins subequal. 

 Scape obclavate; pedicel a little shorter than funicle 1, which is 

 longest of the funicles, much longer than wide, about twice the 

 length of funicle 5, which is somewhat wider than long, funicle 4 

 a little longer than wide, funicle 2 subequal to the pedicel. Club 

 with three distinct joints, the antennae 11-jointed. Mandibles tri- 

 dentate. Hind tibias with two spurs. Pronotum with a more 

 or less distinct, obtuse median carina. Punctuation not quite 

 as dense as usual, the cephalic part of scutum densely, transversely 

 lineolated, 



Male. — Not known. 



Described from two females taken from short grooves under 

 the bark of young eucalypt trees in the forest, October 16th, 1913. 



Habitat. — Nelson (Cairns), Queensland. 



Type. — One of the above specimens on a tag, the head and a 

 hind leg on a slide. In the Queensland Museum, Brisbane.
