Pronotum broad and shield-like; the front lobe strongly coarctate above, 

 the hind lobe broad and flattened and drawn out to a prolonged point 

 behind. Tegmina and wings abbreviated ; the former in the female 

 lateral, about as broad as long, the apex broadly rounded, in the males 

 sometimes fully two-thirds as long as the abdomen and meeting on the 

 back. Abdomen heavy at the base but tapering rapidly backwards, 

 not carinate. Tip of male abdomen strongly upturned, the last ventral 

 segment small and entire. Posterior femora robust, pubescent, the 

 upper and lower carinas destitute of teeth ; the tibiae bowed, heavy. 

 Entire surface with an earthy or dirt-covered appearance. 



Haldemanella robusta sp. nov. 



A very distinctly marked species that differs considerably from both 

 H. tschivavensis and H. magna. White, testaceous, and fawn color. 

 Female very large and robust ; the male more graceful. 



Pronotum, bead and sides of thorax very rough — being ridged, pitted 

 and "warty" iu appearance, reminding one very much of the skin of 

 our roughest toads. Vertex between the eyes very wide, equaling that 

 of the shortest ( $ ) or fully equal to the longest diameter ( 5 ) of the 

 moderately prominent eyes; in the female plane, but broadly and 

 ather deeply sulcate in the male; the apex greatly depressed and 

 closed iu front by a transverse carina; frontal costa very irregular, 

 sulcate above and below the antennae but plane between them, the 

 sides somewhat contracted just below the fastigium and strongly 

 pinched below the ocellus where they terminate, the costa continuing 

 to the clypeus as a swelled ridge; antennae rather heavily filiform, reach- 

 ing only to middle of pronotal shield, 22-jointed. Pronotum very large 

 and shield-like, the surface very coarsely and irregularly rugose and 

 tuberculate ; the anterior lobe without lateral carina?, the middle and 

 posterior lobes with these strongly marked ; anterior edge slightly ad- 

 vanced in the middle ; the posterior lobe greatly but broadly elongate, 

 its edges undulate and toothed; the median carinas perceptible only on 

 posterior lobe; transverse sulci profound, continuous, the third in 

 advance of the middle. Tegmina and wings abortive ; the former, 

 which are broadly rounded iu the female, only reaching to front edge 

 of second abdominal segment, in the male three-fifths as long as the 

 abdomen, tapering ; wings fully as long as the tegmina — both these and 

 the former densely reticulate. Abdomen tapering rapidly in the female, 

 but less so in the male, very faintly carined above; the apex of male 

 quite strongly upturned, the last ventral segment conical ; valves of 

 the ovipositor exserted, short, strong, and unusually blunt. 



Posterior femora coarse aud heavy, the carinae of the outer disk rather 

 inconspicuous, and the pinnae distant and few ; posterior tibiae heavy, 

 bowed, the inner spines much the longest and heaviest, arcuate, very 

 sparsely hirsute as is, in fact, the entire insect.
