The sexual characters are not very well marked. The males have four 

 joints of the anterior tarsi feebly dilated (two in Folpochild) and rarely 

 {Discoderus) with a few squamules beneath. The latter genus has the 

 middle tibiae distinctly arcuate and serrate within. In Cratacnnthus the 

 right mandible of the male has the basal portion which borders the 

 clypeus more elevated, while the upper edge in front of this is much 

 depressed, a similar structure is observed in Aciaopus. 



The Ditomides of Lacordaire should not in my opinion be widely 

 separated from the present group. The only character in which they 

 differ is in the apex of the ligula being plurisetose. Their punctured 

 surface gives them a somewhat different aspect but this has a parallel in 

 Dichirus in the Anisodactyli and Ophonus in Harpali. 



To this group belong also Cratognathus placed by Lacordaire in the 

 Anisodactyli and Puramecus of his Harpali. 



I have introduced Daptus in the above table for convenience of 

 comparison, it does not occur in our fauna. The genera above men- 

 tioned differ to a greater or less extent in the form of the ligula and 

 paragiossae as well as in the extent of pilosity of the tei'minal joint of 

 the palpi. Agoiwderun and Pogonodaptua are the only genera in which 

 I have observed the penultimate joint of the labial palpi to be bisetose. 

 Nothopun and Piosoma have the ligula quadrisetose . and the paraglossfe 

 ciliate externally at tip, the upper surface is also sparsely setose in these 

 genera. In Oratacanthus the paraglossas are very broad and lie behind 

 the ligula, so that when viewed from the front the entire ligula has very 

 much the appearance of that of a Lebiide. 



The name Pogonodaptus is proposed for a small species resembling 

 Daptus arid somewhat also Pogonus (Pogonistes), which has the fol- 

 lowing characters. 



POGONODAPTUS n. g. 



Head moderately large, horizoutal, not narrowed behind the eyes to a neck. 

 Eyes moderately large and prominent, narrowly separated from the mouth. 

 AntennsB arising under a slight frontal ridge, the second joint a little shorter 

 than the third. Clypeus slightly prolonged between the mandibles, narrow, 

 emarginate in front, a seta in each angle. Labrum broadly emarginate, sexsetose. 

 Mandibles prominent, decussating, feebly arcuate, tips acute, a slight tooth at the 

 middle of the right. Mentum broad, feebly emarginate, a short broad tooth at 

 middle. Ligula small, free and bisetose Mt tip and narrowed, the paraglossse 

 falciform a little longer than it, the palpi slender, penultimate joint a little longer 

 than the last and bisetose. Maxillary palpi moderate in length, the terminal joint 

 slender, slightly fusiform, a little longer than the preceding. Thorax transverse, 

 narrowed behind, posterior angles distinct. Body pedunculate. Elytra oblong, 

 parallel, very slightly sinuate near the tip, surface striate, without scutellar stria, 

 a dorsal puncture on the third interval near the second stria. Anterior tibire
