ON A NEUROPTEROUS INSECT FROM N. W. INDIA, BELONGING TO 
THE GENUS DILAB. 
BY R. McLACHLAN, F.L.S, 
The species of the singular genus Dilar are apparently extremely 
rare, and until recently I had never seen a representative of that 
genus, and do not think that any existed in this country, either in 
private or public collections. Up to the present time five species 
have been described. 1. D. nevadensis, Eambur, from the Sierra 
Nevada in the South of Spain (the typical species) ; 2. D, meridionalis, 
Hagen, from the same locality (unique) ; 3. D. turcicus, Hagen, from 
Armenia and Syria ; 4. D. partlienopceus, Costa, from Naples, perhaps 
identical with No. 3 ; 5. Z). Nietneri, Hagen, from Ceylon {vide Hagen 
in Stett. Ent. Zeit., 1866, p. 291 et seq.). Within the last few weeks 
I have found another species, from North-West India, in a collection 
made by Mr. Home, but only represented by males. All the species 
are much alike, differing chiefly in the ^formation of the anal parts, a 
character not easy to discriminate in dry specimens. 
The males of Dilar, which at first sight look much like species of 
Hemerohius, are especially remarkable for longly pectinate antenufe, 
which are found elsewhere in Neuroptera only in some species of 
Chauliodes* 
Mr. Home's insect I describe as follows : — 
DiLAE HORNEI, n. Sp. 
F^isco-castaneus, abdomine pilis longis pallide-Jlmis vestito. An- 
tenna griseo-fusecB, plus minus 1^ -articulates ; articuUs 4 — 21 singulatim 
processu elongato instructis. Alee anticce albido-grisecB, griseo confertim 
punctated vel reticulates ; punctis duohus discalihus {quorum unum iii medio, 
alterum basin versus situm) punctisque circum marginevi apicalem, satura- 
tioribus : posticce punctis prceter disco-medianum fere ohsoletis. Pedes 
Jlavi, pilis longis concoloribus vestiti. Abdomen fuscum ; valvis analibus 
Jimbriatis,Jlavis. Long. corp. 2'"; exp. alar. 11'". 
Sead castaneous, sometimes slightly suflused with blackisli ; a 
large rounded tubercle on each side of the middle, and the raised hinder 
margin, yellowish with yellow hairs ; face fuscous, a deep and broad 
transverse sulcus before tlie clypeus ; mandibles prominent, yellow, 
produced into an acute piceous point. Antemiee grey, with short 
greyish-yellow pubescence ; about 27-jointed ; basal joint fuscous ; 
third joint with a short tooth, the 4th to the 21st, cacli with a long 
* Euptilon, whirli is founded on a figure in Drury, and is represented with pectinate antennaB is 
most probably mythical.— R. McL,
