variegated with black ; palpi and bnsnl joints of the antennae testaceous, joints 

 4-11 of the latter black; leg-s testaceous, the outer portion of the posterior 

 femora infuscnte or black, the posterior tibiae and tarsi, and sometimes the 

 other knees, tibiae, and tarsi also, partly infuscate ; the surface-puncturing 

 extremely fine and close, that of the elytra more distinct and with the inter- 

 spaces riigiilose. Head hollowed down the middle between the eyes, the latter 

 very large ; antennae slender, extending to far beyond the elytra. Prothorax 

 transverse, narrower than the head, excavate in the middle at the base. Elytra 

 two or two and one-half times the length of the prothorax. Abdomen very 

 elongate ; seventh dorsal segment long, forcipiform, the subconical apical pro- 

 cesses more or less divergent in J, and very slightly curved inward in cT; 

 seventh ventral segment in J armed on each side with a long, curved, narrow 

 process which is widened at the base and feebly emarginate near the tip, the 

 two ])rocesses forming a second shorter pair of forceps iu this sex (ligs. 1, 2). 

 Legs simple iu the two sexes. 

 Length 6-8 mm. (J?.)

Found conimonlj in Almora, flying about shrubs, tlie long series 

 before me including eleven males. Tlie form of the terminal aljdomiiial 

 segments in J is not imlike that of the Mexican I. diclielifer Champ.

 Pic (Melanges exot.-entom. xviii. ]>. 13, 191G) [sex not given but almost 

 certainly $ ], ty[)e from Wallurdi, 8. India, is probably a closely allied 

 insect ; it is described as having the bead nigro-trinotate posteriorly, the 

 ti'ansverse black fascia on the prothorax undulate, and the length is 

 stated to be 10 nun.

Xgvx like /. hhna/auiis, differing from it as follows : black or fuscous, the 

 bend with an oblique streak or spot on each side between the ej'es and usually 

 a transverse arcuate mark in front, the antennal joints 1 and 2, the elytra some- 

 times with the margins anteriorly, the apical margins of the abdominal seguients 

 1-6, and in one example the sides at the base also, testaceous or flavescent, the 

 elytra in some specimens Avith a rather large yellowish spot at the apex; the 

 head and prothovax a little more distinctly purictured, the head sulcate down 

 the middle ; the antennae shorter in both sexes, scarcely extending beyond the 

 apices of the elytra; the rigid, subconical, forcipiform appendages of the 

 terminal dorsal segment of the abdomen similarly shaped in the two sexes ; the 

 seventh ventral segment of J armed on each side with a short, broad, curved 

 process, which (as seen in profile) is obliquely truncate distally and narrowly 

 produced at the tip (tigs. 3, 4). 



Var. The antennal joints 1-3, and the base of the elytra narrowly, flavo- 

 testaceous, the elytra with a large yellow patch at the apex [ $ ].
