(J . Anterior tarsal joints 1-3 with a narrow black comb 

 along their inner edge ; terminal dorsal segment emarginate 

 in the middle at tip ; sixth ventral segment (PI. XII. 

 fig. 49 g) deeply, narrowly, obliqnely bi-excised at apex, the 

 median portion shorter than the broader, truncate, cnrved 

 lateral portions. Genital armature (PI. XII. fig. 49) : 

 lateral lobes long, narrow, more or less emarginate on their 

 lower edge before the tip ; median lobe long, almost straight, 

 curved downward into a blunt point at apex.

A small, narrow, shining, pale testaceous form, with the 

 tips of the elytra black ; tlie head usually infuscate around 

 the eyes, sometimes wholly testaceous, or with the base 

 black (those from Penang and Borneo); the basal joints 

 of the antennae, the tibise and tarsi, and in some specimens 

 the apices of the femora also, infuscate, rarely entirely 

 testaceous ; the antennae long and slender, with the almost 

 simple apical joint about as long as the tenth ; the eyes very 

 large, approximate in (^ , narrowly separated in ? . Amongst 

 the numerous closely allied insects from the same region, 

 /. paUidiculor, as here identified, is recognizable by the 

 tnlobed sixth ventral segment of the male, and the non- 

 elongated eleventh antennal joint in the two sexes, a 

 character used by Pic in his first table of the Javan and 

 Snmatran forms. JNIales from the localities quoted have been 

 dissected: those from Java, Tenasserim, and Burma agree 

 inter se ; but the one from Penang (with blacker head) has 

 the median lobe of the last ventral segment notched in the 

 middle^ that from Perak having the corresponding lobe 

 longer, narrower, and rounded at the tip. 



&\ . Idgia dasytoides, sp. n. 



? . Elongate, very narrow, slender, moderately shining, 

 closely cinereo-pubescent, and sparsely nigro-setose ; green 

 or brassy-green, the antennse piceous, the basal joints and
