ever, differ greatly in size and in the armature of abdomen and thorax. The number of 
the thoracic spines varies considerably, but the cephalic spines are constant in all the 
four examples which I have examined. I place this and the allied species in the genus 
Lonchodes on account of the general form, antennæ, and cleft apical segment of the males 
agreeing well with the rest of the numerous species forming the genus. The shape of the 
apical segment of the abdomen in the females seems to point to a connexion between 
Lonchodes and Heteropterya. 
Hab. Dorey, New Guinea (Wallace). 
There are four examples in Mr. Saunders's collection, two of which are ticketed as 
having been taken in copuld. The male in this pair has the middle part of the meso- 
thorax quite smooth and unarmed, whilst the same portion of the segment in its partner 
has two transverse rows of spines, four in each row. A second specimen of the male 
agrees in all respects with the one just mentioned, except in the number of the thoracic 
spines—the middle part of the mesothorax having two pairs, placed in the same position 
as those of the female. 
LONCHODES HisPA, n. sp. Mas. Gracilis, cylindricus, viridis; capite bispinoso; antennis 
longis, setaceis; prothorace antice bi-, postice unispinoso ; mesothorace medio 4- vel 
6-, postice 5-spinoso ; metathorace 6-, 8- vel 10-spinoso ; abdominis segmentis quatuor 
primis trispinosis, quinto unispinoso; femoribus apice infra denticulatis. Variat 
femoribus apice nigris.—Long. corp. 2" 1"; mesothor. 7" ; metath. 34”. 
-Lonchodes Hispa has a close resemblance to L. Doreyanus, differing chiefly in the four 
basal segments of the abdomen having each three spines instead of one. Unfortunately 
the female sex is at present unknown, so that it is difficult to decide whether iti is a mere 
variety of Z. Doreyanus or a distinct form. 
The spines are longer than in the males of either L. Doreyanus or L. Wallacei; the 
anterior division of the metathorax has near the hind margin three spines, and the 
posterior division also normally three; but in one example the lateral ones are small, and 
in a third obsolete; the sides of the metathorax have each either one or two spines; so 
that the total number on this segment of the body varies from six to ten. The coxæ 
have all a distinct, acute spine. The apical dorsal segment of the abdomen is of the 
same shape as in the two allied species; the central line of the three terminal dorsal 
segments is strongly elevated. 
Hab. There are three examples in Mr. Saunders's collection—namely, one from the island of Salwatty, 
and two from New Guinea. 
LONCHODES FLAVICORNIS, n.sp. Mas. Gracilis, cylindricus, corpore tenuissime trans- 
verse ruguloso, leviter granulato, subnitido, castaneo-olivaceo; capite oblongo, inter 
oculos acute bispinoso; antennis setaceis, dimidio „basali nigro, apicali pallide 
flavo; thorace inermi; abdomine cylindrico, segmentis 7° et 8° sexto vix minoribus, 
9° elongato attenuato profunde fisso ; pedibus gracilibus, inermibus, tarsis simplicibus.
