240 Mr. E. Shelford's Studies of the BlatticU. 



Escala insignis, n. sp. (Plate XV, fig. 6.) 



^ . Rufo-testaceous ; head castaneous, anterior and lateral mar- 

 gins of pronotum hyaline ; wings clear hyaline with rufous shading 

 on either side of the apical triangle ; abdomen and legs testaceous. 

 Tegmina with thirteen costal veins, anterior ulnar vein bifurcate, 

 posterior ulnar vein ramose. Wings with eleven costal veins, first 

 axillary vein bifurcate, apical triangle larger than in the two preced- 

 ing species. Supra-anal lamina not much produced, trigonal ; sub- 

 genital lamina ample with two acuminate stjdes and an asymmetrical 

 lobe, covered with short setae but not armed with hooks. 



Total length 115 mm.; length of tegmina 9'5 mm. 



Australia. Two examples (Oxford Museum). 



This species is structurally very close to Theganopteryx 

 and may be regarded as the least highly modified species 

 of the genus Escala. In general facies the species resemble 

 each other closely, but the nature of the sub-genital 

 lamina affords admirable specific characteristics, and if this 

 is examined there can be no possible difficulty in distin- 

 guishing the species. I have seen no female examples of 

 the genus. 



Genus Anaplecta, Burm. 

 Anap)lGcta maculata, n. sp. (Plate XV, fig. 7.) 



$. Castaneous; head rufous, antennas fuscous; lateral margins 

 of the pronotum and tegmina pellucid ; a testaceous macula in the 

 centre of the pronotum but nearer the posterior than the anterior 

 margin ; wings infuscated ; the ventral surface of the abdomen, the 

 legs and cerci testaceous. Tegmina with seven parallel costal veins, 

 the discoidal field traversed by four longitudinal veins, the anal vein 

 impressed. Wings with five costal veins joined by oblique venula?, 

 the marginal field not dilated, the medio-discal field crossed by six 

 transverse venula?, the first of which is oblique, no longitudinal vein 

 dividing the apical part of the medio-discal field, two transverse 

 venuhu anteriorly connecting tlie median with the ulnar vein, the 

 first axillary vein tri -ramose, apical area two-fifths of total wing- 

 length. 



Total length 6"5 mm. ; length of tegmina 5 mm. 



Pundaloya, Ceylon (E. E. Green coll., Feb. 1897). 

 Two examples (Oxford Museum). 



This and at least two other species are in the British 

 Museum under the label Phyllodromia ( ? ) gyrinoides, 

 Wlk. I have compared A. maculata, mihi, and the two
