than the tibial joint, convex,' subconical, with the external margins rounded, the inter- 

 nal subacute, with three spinulae, the two anterior subapproximated ; the apical one 

 large and acute. Inferior surface with four spinulao on the external and two on the 

 internal margin ; internal surface with two spinulae, which with the angular process 

 form a series directed obliquely upwards. Lateral appendages dark chestnut, punctured, 

 with the apex elongated, bifid, or simple. Preanal scale flattened, elongate, with the 

 posterior margin narrow and transverse. 



This species very much resembles C. aurantiipes and C. obscurus, but differs 

 from both in the number and arrangement of the spines on the inferior sur- 

 face of the legs, and also in the greater depth of the excavation. I have re- 

 ceived it, in various stages of growth, from about one inch in length to nearly 

 four inches, and in very great abundance, from Paramatta, where it appears 

 to be the prevailing species. On this latter account I have named it C.fcecun- 

 dus. The smallest specimens agree with the largest in almost every particular 

 of form, colour, number of joints to the antennae, and number and arrange- 

 ment of the spines on the legs. The chief difference is in regard to colour, 

 which in the youngest individuals is indistinct and often confused.

This species varies much in colour, but always preserves the same general appearance. The 

 dark blue antennae and yellow legs contrast very prettily with the red head and poste- 

 rior pair of legs. The labium is thickly punctured : the dental plates are small and 

 narrowed anteriorly, with the margin rounded : teeth eight, minute, black, distinct. 

 Posterior pair of legs short and thick; femoral joint convex, subconic, a little longer 

 than the tibial, with three acute spinulae on the rounded internal margin, the apical one 

 the largest, bifid ; internal surface with two spinulae, which with the apical one form a 

 series diagonally upward. Inferior surface with four spines, arranged in two alterna- 

 ting equidistant series on the external margin, and three in a single series on the in- 

 ternal. Lateral anal appendages elongated, minutely punctured, with the apex acute 

 or bifid. Preanal scale subquadrate, margin straight.
