48 ON THE PSELAPHIDyE OF AUSTRALIA, 



Sp. 21. B. hmatica. R. L. King, (fig. 8. h.) 

 Ferrugineus setosus ; capite 4 foveolis impresso ; thoraco 

 breviter obcordato foveis 3"^"' linea conjunctis impresso ; 

 elytris stria suturali altera discoidali impressis, lateribus 

 subparallelis. Abdomine margin ato, segmento 2''" reliquis 

 majori. 



Long. -^ poll. 



Under stones, Parramafcta. 

 This species somewhat resembles B. hortensis, from which it 

 is distinguished by its being narrower in proportion to its length, 

 as well as by the markings of the head and thorax. The thorax 

 is longer than the head and a little wider. In the antennte, (8. h.,} 

 the tenth joint is decidedly wider than the base of the 

 eleventh. 



Sp. 22. B. eledrica. R. L. King. (fig. 9. h.) 

 Castanens, nitidus, sub lente setosus ; capite 4 foveis im- 

 presso , thorace obcordato 3*"^ foveis ad bansi linea 

 transversa conjunctis instructo ; elytris stria sutm^ali 

 altera discoidali impressis cum plicatura humerali ; 

 abdomine marginato elytrorum latitudine, segmentis 

 inaequalibus. 



On fence at dusk, Parramatta. 

 There is a remai'kable similarity between this species and the 

 preceding (B. lunatica). It is, however, readily distinguishable 

 from that species by its smaller size, lighter colour, and tlie fine- 

 ness of its setas, which indeed are hardly distinguishable, except 

 with a powerful magnifier. The terminal joint of the anteuna?, 

 fig. 9. h., in this species is comparatively larger and the penulti- 

 mate smaller than in the preceding — so much so that, except 

 upon close inspection, the club appears to be formed of the 

 terminal joint alone, the penultimate being narrower at its 

 widest pai't than the base of the last joint. 



I have only found it, hitherto, on fences at sunset when the 

 ail' is charged with electricity ; when a thunderstorm is rising of 

 an evening it may almost with certainty be looked for on the 

 summit of my paling fence.
