290 MEMOIRS OF THE QUEENSLAND MUSEUM. 
Habitat: Gordonvale (Cairns), Queensland. Mantid eggs in forest, July 4, 1912. 
Types: No. Hy 1170, Queensland Museum, Brisbane, two pairs on separate tags. 
Eleven females of beneficiwm reared from a mantid egg case found on an Eucalyptus tree 
in forest at Gordonvale, Queensland, April 12, 1913. Examined from them 21 femora and 20 
antennee. The femoral teeth were six 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 cases 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 antenne 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 beneficiwm 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 previous formule of this number of teeth. 
5. PODAGRION WASHINGTONI new species. Female. 
Length, 5. mm., excluding ovipositor. 
At once distinguished from beneficium Girault by the fact that the posterior femora 
beneath bear more than seven teeth, the antenne 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 slightly longer than wide and 
in general coloration. Differs from olenus Walker in having the first two pairs of femora 
rufous, 
Brassy metallic green, the abdomen (dorsal aspect) with a broad orange yellowish 
band encircling it just out from (not immediately at) base, ventrad yellow along proximal 
half or more, the petiole very short, the ovipositor long and brown, the valves black; coxee 
dark, fuscous toward tip, the rest of the legs except posterior femora, reddish brown. Venation 
dusky, the’ wings hyaline. Antenne dusky brown, the flagellum uniformly colored, the 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 joining it 
which is carinated (dorsal aspect); several obscure, irregular carine 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 tibie 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 size, 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 the 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 enumerated as 
distinct teeth.
