MUTIDLA DALILA, n. sp. 



$ . Black, with the whole thorax ferruginous red ; head, thorax 

 and abdomen, under side and legs bristling with long dense hairs 

 black on the upper side, greyish white underneath ; abdomen nearly 

 sessile, elongate ovate, first segment with an apical yellow silky 

 band interrupted sub-triangularly in the centre, second and third 

 segments with a similar but slightly broader band also interrupted in 

 the centre, that of the third segment a little more broadly so than 

 that of the second, but both are continued underneath and are 

 almost as dense as on the upper side. 



Head very little broader than the anterior part of the pronotum, 

 sub-quadrate, deeply reticulate foveate, space behind the eyes equal 

 to the length of the eye ; second joint of antennic short, about one- 

 third of the length of the fourth ; mandibles very long ; thorax 

 hexagonal, very little longer from the apex to the declivity of the 

 mctanotum than broad, sti'ongly crenulate and bi-sinuate laterally 

 and triangularly dilated towards the middle ; the pronotum is 

 arcuate with the angles acute and the space between the lateral 

 triangular part and the sharp angle of the declivity of the meta- 

 notal part which is roundly sloping with the sides sub-crenulate is 

 plainly emarginate ; the surface of the whole thorax is regularly 

 foveate punctate ; basal abdominal segment short, fitting against the 

 base of the second but not quite as broad, covered like the second 

 with elongate foveate punctures, on the second segment these 

 punctures are very elongated, their walls forming a longitudinal 

 striation ; on the other segments, except the last, the punctures are 

 simpler, the last segment is longitudinally strigillate all over and is 

 quite hairless ; the very bristly tibiae have each seven double series 

 of strong spines ; the keel under the final segment is slightly bi- 

 sinuate and truncate in front. 



The shape of the head and prothorax recall that of M. (StenomiUilla) 

 capicola and hcro'e, P^r., but the prothorax is more serrate laterally. 

 It does not, however, belong to the sub-genus Stenomutilla, owing 

 to the abdomen being non-petiolate.
