 note. 



$ maj. Varying from brownish red to brownish black ; the 

 mandibles, flagellum of the antennae and legs, sometimes the 

 metanotum also, yellowish red to chestnnt-red ; head, pro- and 

 mesonotuin very smooth, polished arid shining ; the head anteriorly 

 and the mandibles more or less finely longitudinally striate ; the 

 metanotum above finely transversely striate, the sides minutely 

 but densely rugulose, opaque ; pedicel finely rugulose and opaque 

 also ; pilosity more or less abundant (on the other two species 

 almost entirely and in some specimens quite wanting) ; pubescence 

 very sparse, except on the antennae and tarsi. Head, thorax, 

 pedicel and abdomen typical of the genus. 



min. Smaller, with the head somewhat smaller in proportion, 

 generally lighter in colour, the flagellum of the antennae and the 

 legs being a clear reddish yellow. Sculpture and pilosity as in 

 the maj. 



Length, $ 3'5-7'5 mm. 



Hob. Kecorded so far from Western and Southern India, Ceylon, 

 and Burma. 



This is a race barely separable from H. criniceps, Mayr. 

 Dr. Forel has described (Z. c.) a variety under the name H. glabro- 

 criniceps, intermediate between the two species. Also var. clarus, 

 altogether of a yellowish red, more or less clear, with the abdomen 

 brown, red at base, and the antennae and legs clear yellow. This 

 latter variety has been recorded also from the Siwaliks.

 p. 467, $ . 



" $ maj. Piceous, the mandibles and legs obscurely ferruginous, 

 the tibiae and flagellum of the antennae paler ; pilosity sparse ; 

 shining ; metanotum opaque. Head smooth, sparsely punctured ; 

 the front, cheeks and occiput lightly longitudinally striate; clypeus 

 very smooth, without the usual teeth ; mandibles cribrate-sulcate, 

 shining ; the 8th joint of the flagellum of the antennae scarcely 

 shorter than the following joints. Thorax : the pronotum arid 

 mesonotum above distinctly punctate and longitudinally rugulose, 

 slightly shining ; the sides of the meso- and metanotum densely 

 punctured, the latter even obsoletely transversely rugose, posteriorly 

 lightly impressed, in the middle without teeth or elevated earinae. 

 Nodes of the petiole very finely punctate. Abdomen smooth. 



" Length, $ maj. 5-6 mm." (Emery .) 



Hob. " Upper Burma, Minhla (Commotto')" 



This species is entirely unknown to me, but apparently, except 

 for the absence of the clypeal teeth, is almost identical with forms 

 of a species I have always looked upon as H. criniceps, Mayr, 

 collected at various localities in Burma.
