266 MEMOIRS OF THE QUEENSLAND MUSEUM. 



2. PSEUDELACHERTEUS NIVEICORNIS new species. 

 Female: — Length, 1.05 mm. 



Differing from the three species so far known in having the antennae wholly yellowish' 

 white like the legs while the body is otherwise as in silvensis except that the abdomen is lemon 

 yellow in ground color. Margining black of the abdomen broad. Scutellum finely sheened. 

 Funicle joints globular to subglobular, subequal to the pedicel. Petiole of abdomen distinct. 

 Mandibles 5-dentate. 



From one female caught by sweeping in forest, March 2, 1914 (A. P. Dodd). 



Habitat: Cooktown, Queensland. 



Type: No. Hy 265 fj, Queensland Museum, Brisbane, female on a tag, head and hind 

 legs on a slide. 



3. PSEUDELACHERTEUS INVENTRIX new species. 



Female: — Length, 1.50 mm. 



Very similar to silvensis but segment 2 of abdomen is black and there are 2-3 dusky 

 cross-stripes on distal third of abdomen. Pedicel subequal to funicle 1. In the single 

 specimen, one caudal tibia appeared to bear two spurs but I could find only one in the other 

 species upon re-examining the types. 



From one female captured in forest, June 10, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. HyS657, Queensland Museum, Brisbane, the specimen on a tag; hind legs- 

 and head on a slide. 



Genus ENTEDONOMOKPHA Girault. 18 



1. ENTEDONOMORPHA TENNYSONI and ENTEDONOMORPHA RENANI Girault, 



These two species are very much alike. The genotype is metallic like renani. The 

 two type bodies have been carefully re-examined and remounted together on a slide. The 

 species differ as follows: 



renani. tennysoni. 



Petiole stout. Petiole narrower. 



Scutum purple. Scutellum purple. 



Abdomen broad, brown-yellow discally except Abdomen slender, light yellowish discally 



venter which is black along proximal two above and below. 



thirds. Pronotum uniformly sculptured. 



Caudal margin of pronotum smooth. Scutum flat. 



Scutum subconvex. Parapsidal furrows just attaining the latero- 



Parapsidal furrows not quite attaining the caudal angle of pronotum. 



latero-caudal angle of pronotum but ending 



laterad. 

 Abdomen with a subfuscous stripe across 



center. 



A female of renani was captured March 30, 1913, type locality. The reticulation of 

 the scutum is coarser than that of the scutellum, its cephalic margin glabrous. Pronotum 

 transverse-quadrate. 



1 B This genus upsets the present tribal arrangements, the spurs of the caudal tibiae varying from one to two. 

 The unique structure makes belief in parallelism most difficult. We are certainly ignorant !
