SHELFORD, BLATTODEA. 41 



Fam. Corydiida?. 



Gen. Aliacoilipsa nov. 



Finely pubescent. Eyes approximate. Antennae filiform, shorter than bod)'. 

 Pronotum cucuUate, covering vertex of head, small, sides deflexed, posterior border 

 arcuate. Tegmina and wings elongate, extending considerably beyond the apex of 

 the abdomen ; costal veins few and irregular, discoidal area of tegmina reticulated, 

 axillary veins obsolescent ; posterior part of wing ample, median vein simple, ulnar 

 vein ramose at extremity. Supra-anal lamina of cT transverse. Cerci moderate. Tibiae 

 weakly armed, spines on posterior pair triseriate with 4 apical calcaria, 4 apical 

 calcaria on front pair. Tarsal claws with arolia. 



In genera] appearance the genus resembles Latindia Stal but is distinguished 

 from that and its allies, Hemilatindia Sauss. and Paralatindia Sauss, by the triseriate 

 arrangement of the tibial spines. From Holocompsa Burm. and Hypercompsa Sauss. 

 it is distinguished by the long tegmina of uniform texture; Ipisoma BoL. is charac- 

 terised mter alia by the reduced tegmina. It is probable that a considerable number 

 of species of these fragile little cockroaches are still unknown to science, they are 

 rare in collections but probably because they have been neglected by most collectors 

 in favour of larger and more conspicuous forms.

(PI. 2, fig. 10 and 11. PI. 3, fig. 9.) 



o'. Head dark castaneous, mouth parts testaceous; frons not swollen, ocelli 

 large. Antennae fuscous, filiform, of 30 joints, joints longer than broad and increasing 

 in length distally. Pronotum rufo-testaceous, disc with two oblique impressions. 

 Tegmina long, overlapping strongly, finely pubescent, membranous, rufo-testaceous 

 with a broad humeral vitta extending to half the total length, fuscous ; mediastinal 

 vein with a few incomplete branches, 6 costal veins, their ends not reaching the 

 anterior margin of the tegmen, anterior ulnar ramose at its apex, posterior ulnar 

 ramose, transverse anastomoses uniting the branches, anal vein curved reaching the 

 sutural margin at a point one-fifth of the total length, axillary veins obsolescent. 

 Wings hyaline, flavo-testaceous on the sutural margin, mediastinal vein simple, 6 

 irregular costals, ulnar vein ramose at its extremity, posterior field ample larger than 

 the anterior field. Abdomen castaneous, flavo-testaceous at base, supra-anal lamina 

 transverse, sub-genital small, right style absent, left style represented by a flattened 

 lobe, the origin of which is hidden by the penultimate sternite. Cerci moderate, testa- 

 ceous, segmentation obscure. Legs testaceous ; front tibiae with only 4 spines on 

 the anterior border, 2 being apical, 3 on the posterior border, 2 being apical; spines 

 on mid- and hind-tibiae triseriate; front femora with no genicular spine, formula of 

 apical spines i, i, i.
