378 AUSTRALIAN C0RDULIIN.5;, 



in the new year. I do not know if they die out or go elsewhere, 

 but they cannot be found about here in January. They frequent 

 thick ' blackboy ' and palm-scrub close to the brook, but I never 

 saw them hawking about on the water. They sit on the leaf of 

 a ' blackboy ' or palm, flying off at the least alarm, usually up- 

 wards over the scrub, and alight again a chain or two away on 

 another leaf. If one can see or note the spot, they may be 

 captured fairly easih'. On the wing, they are very active and 

 mostly high out of I'each. I once saw a pair in cop., but failed 

 to get them. Although fairly numerous, they are not easily 

 caught, and it takes a lot of careful hunting to get a few. On 

 some very good days I have taken four, but mostly only one or 

 two. The fine, highly-coloured males are especially smart, keep- 

 ing well out of my reach." 



Types: (J$., and series of cotypes, in my collection. 



Lathrocokdulia, nov. gen. (Plate x., fig."2). 



Head and thorax robust. Legs short. Abdomen slender, 

 cylindrical. Triangles of all wings and subtriangle of foi'ewings 

 free. Sectors of arculus separated at bases. Arculus placed 

 about midway between first and second antenodals. Triangle of 

 hindwing nearly recessed to level of arculus. Second cubital 

 cross-vein of hindwing present, foi'ming a small " subtriangle." 

 Post-trigonal space of forewings with one row of cells \i\) to near 

 tip of wing. Anal loop rather sliort, only moderately well 

 defined, with no straight apical boundary, and no defined longi- 

 tudinal bisector. A small cross-vein low down in anal triangle 

 of hind wings. 



Type: LathrocorduHa metalHca, n.sp. 



Allied to Syncordulia* from which it can be at once separated 

 liy its more robust build (especially its large head and thorax), 

 its more open venation and smaller number of ante- and post- 

 nodals, the greater amount of recession of its hindwing-triangle, 

 and its more poorly developed anal loop. Also closely allied to 



*It must be understood that I refer here to ^'. atrifrons McF.ach., which 

 I assume is congeneric with the t3'pe S. (jracilis Burm., of which no 

 really reliable or sufficiently full descriptions are available..
