290 MEMOIRS OF THE QUEENSLAND MUSEUM. 



Ilabilat : Gordonvale (Cairns), Queeuslaiul. Mantid eggs in forest, July 4, 1912. 



Types: No. Hy 11.70, Queensland Museimi, Brisbane, two pairs on separate tags. 



Eleven females of heneficium reared from a mautid egg case found on an Eucalypttis tree 

 in forest at Gordonvale, Queensland, April 12, 1913. Examined from them 21 femora and 20 

 M'ltennsB. The femoral teeth were si.\ in number 18 times when the formula was from proximaa 

 — long, short, long, short, long, long; tooth 4 always distinctly shorter than 5, tooth 2 shortest. 

 Five teeth occurred in one case (asymmetry), the small second tooth absent. Seven teeth 

 occurred in the remaining two eases and were asymmetrical — in one the formula was long, 

 short, long, short, short, long, long (with 2 longer than 5, here extra) ; in the other the formula 

 was long, short, short, long, short, long, long (with 2 shorter than 5). 



In this species six teeth seem usual ; the distal two teeth usually about equal in length 

 but the last distinctly broader at base. The twenty antennte showed no marked variation, the 

 distal two funicle joints always distinctly wider than long, the proximal two longer than wide. 

 Thus, in this genus, the antennal characters seem to be a better specific character than the form 

 and number of femoral teeth, though in the latter the range of variation, perhaps, is not great 

 and a deviation of three or four (as regards number) in either direction from a known 

 formula would be indicative of specific distinctness. 



A twelfth female of heneficium captured December 2, 1912 by sweeping in forest at 

 Gordonvale showed no antennal variation but asymmetrical development of the femoral teeth, 

 there being six teeth on one of the usual formula and seven on the other, the formula of the 

 latter similar to one of the pre\'ious formulic of this number of teeth. 



5. PODAGRION WASHINGTONI new species. Female. 



Lengtli, .5. mm., excluding ovipositor. 



At once distinguished from heneficiuin Girault by the fact that the posterior femora 

 beneath bear more than seven teeth, the antenna; are reddish brown, the median carina of the 

 propodeum divides at a point at about half way to the middle from base, the rufous femora of 

 the first two pairs of legs, in the distal two funicle joints being sligljtly longer than wide aud 

 in general coloration. Differs from olciius Walker in having the first two pairs of femora 

 rufous. 



Brassy uietallic green, the abdomen (dorsal aspect) with a broad orange yellowish 

 band encircling it just out from (not inunediately at) base, ventrad yellow along proximal 

 half or more, the petiole very short, the ovipositor long and brown, the valves black; coxs 

 dark, fuscous toward tip, the rest of the legs except posterior femora, reddish brown. Venation 

 dusky, the wings hyaline. Antennai dusky brown, the flagcllum uniformly colored, Ihe funicle 

 joints all slightly longer than wide but shortening slightly toward apex in succession, the club 

 joints unequal, the club slightly enlarged. Densely punctate, including the propodeum; the 

 branches of the median carina run nearly laterad ending in the lateral margin and jomiiig it 

 which is carinated (dorsal aspect) ; several obscure, irregular carinse from cephalic margin 

 running short distances caudo-laterad, one apparently going into the branch of the median 

 carina. Metallic part of abdomen shining, with a polygonal or scaly sculpture. Knees and 

 tarsi whitish, the posterior tibiaj darker centrally. Posterior femora beneath with nine teeth, 

 the first large and acute, the third, fifth, sixth and seventh smaller, moderate, more or less 

 equal, teeth 2 and 4 smallest, 4 only half the si?e, or less, of 2; teeth 8 and 9 together forming 

 a large mound-like projection, incised along its tip to form the two teeth, the base of the two 

 more than twice tlu' length of the base of the tooth and proximad near base of the proximal 

 side are two minute pimple-like teeth or projections, rather obscure and not eniunerated as 

 distinct teetli.
