206 THE CANADIAN ENTOMOLOGIST 



collected along the Babinda Creek. North Queensland. The difficulties in the 

 way of collecting these insects in Queensland are well shown by the foUqwing 

 paragraph from one of Dr. lllingworth's letters : 



"Sweeping along streams is almost out of the question here in the 

 tropics, where every bush is provided with recurved hooks to hold one up. I 

 have torn a number of nets full of holes trying to do it and seldom make a 

 catch. Most of the specimens I found either singly on the vegetation, in the 

 scrub, or in caverns under the large rocks along the streams." 



A few additional specimens were secured by Mr. Alan P. Dodd. I would 

 express my indebtedness to Dr. Illingworth and Mr. Dodd for this interesting 

 material. The types of the new species will be preserved in the writer's 

 collection. 



Genus Dicranomyia, Stephens. 

 Subgenus Thrypticomyia, Skuse. 



The type of the subgenus is D. {7\) aureipennis (Skuse) (Australia). 

 Other species belonging to this group are D. arcuata (Alexander) (Japan), 

 longivena (Edwards) [Indidi), scychellcnsis (Edwards) (Seychelles Islands) and 

 probably saltens (Doleschall) (Oriental Region). Two additional undescribed 

 species were included in the present material. 



Dicranomyia (Thrypticomyia). doddi, sp. n. 



General coloration dark brown ; thoracic pleura obscure brownish yellow ; 

 tarsi largely white; wings with a distinct brown suffusion that is uniformly 

 distributed over the wing surface ; stigma large ; supernumerary crossvein in 

 cell So, only a short distance before r. 



Male. — Length 6 mm. ; wing 5.8 mm. 



Female. — Length 5.5 mm.; wing 6 mm. 



Rostrum obscure yellow ; palpi dark brown. Antennae dark brown. 

 Head greyish brown. 



Mesonotum dark brown. Pleura obscure brownish yellow. Halteres long 

 and slender, dark brown. Legs with the coxae and trochanters dark brown ; 

 femora dark brown, slightly paler basally; tibiae and about the basal one-half 

 or slightly more of the metatarsi dark brown ; remainder of the tarsi white or 

 faintly reddish white. Wings with a uniform brownish suffusion ; stigma large, 

 elongate-oval, dark brown; veins dark brown. Venation: Sc ending opposite 

 the origin of Rs ; Sc,^ pale, removed from the tip of Sc, , the latter being about 

 equal to the deflection of R ^ ; supernumerary crossvein in cell Sc a little 

 more than the length of r before this latter crossvein; extreme tip of R, 

 atrophied;; inner end of cell 1st M,^ slightly arcuated; cell 1st M^ about equal 

 to vein Mg beyond it; basal deflection of Cu , near midlength of cell 1st M,^ . 



Abdomen dark brown. 



Habitat. — North Qvieensland. 



Holotypc, ^, Gordonvale, June, 1920 (A. P. Dodd). 



Allotopotype, $. 



Paratopotype, J*. 



This crane-fly is dedicated to its collector, Mr. Alan P. Dodd. Its closest 

 relative is apparently D. seychellensis (Edwards) which differs mainly 'n the 

 coloration of the wings.
