DORCFS. 107 



deiiseiy ruiioso and ()j)<i(ni(\ The inmtiiiit is coarst'ly rujiosp. 

 The //H'fasferunm is tiucly puiicturt'd in the inickllc, (l«>Msoly 

 rugose at the sides and the abdomen is closely ])unetiM'ed. 

 The terminal fork of the front tibia is short and broad. 



(^. Rather depressed. The head is smooth, with the clyju^al 

 process short and rather broad, the angles rather sharp. 

 The eye is small and almost divided by the eanthus, which 

 is very narrow and not at all prominent. The sides of the 

 head are feebly prominent behind the eyes. The protwhim 

 is smooth, margined at the base but not in front, the lateral 

 mai-gins excised behind the front angles, forming a sharp 

 angle behind the e.xcision, and straight and conv^ergent to 

 the basal angles, which ait' shar|). The 'li/tra are smooth or 

 sulcate. 



Variation of the male. 8mall specimens resemble the female. 

 The pronotum is shining, with the sides rugosely ])unctured, 

 and the elytra are closely grt)oved, with densely rugose sides 

 and apices. The head is smooth and shining, with its anterior 

 part closely punctured. The niandibles are short, strongly 

 curved, with a very small blunt tooth near the middle of the 

 inner edge. The anterior excision of the sides of the thorax 

 is absent in small specimens. In larger examples the j)unctures 

 disappear from head and thorax and the surface becomes 

 coriaceous and dull ; the elytral grooves gradually disap})ear, 

 leaving only a close and fine puncturation, except for the 

 rugose sides. In large specimens the elytra are slightly 

 coriaceous and without punctures. The mandibles become 

 longer and less curved, the internal tooth becomes broad and 

 at a further stage a|)pears as two separate teeth, which are 

 suj)plementcd by another near the ti}). The hindmost tooth 

 is always more ])rominent than the rest and in large s])ecimens 

 is rather strong. A very variable number of minute teeth 

 may ap])ear be;^ond it, not always alike on the two sides. 

 The situation of the large tooth varies greatly. It is often 

 near the base {tityiis type) but sometimes more advanced and 

 may even approach the middle {tethys).
