* Habitat in Madagascaria.” 
Very much elongated, linear, punctate, pubescent, with the head and thorax reddish. 
Elytra long, obscure, covered with brown hairs. Abdomen obscure, with the margins of 
the segments bearing yellow hairs. Legs and antenne red. | 
From Madagascar. 
Genus ITHYPHENES (i6vc, obvious ; $évo, I kill, —alluding to the projecting mandibles). 
Corpus elongatum, valde depressum. Caput latum, epistomate porrecto et emarginato; oculis parvis, 
haud basin capitis attingentibus; sulcis antennariis brevibus. Labrum integrum. Maxille ad basin 
uncinatz. "Thorax subcordiformis. Elytra striata. Abdomen supra segmentis ultimis tribus expo- 
sitis, segmentis omnibus fere zequalibus, secundo solum paulo minore. 
Body elongate, flat, and much depressed*. Head broad, with the sides rounded, and 
widest behind the eyes; epistome with a broad projection which is emarginate, and 
each side of the projection is emarginate also; eyes small, far forward, at the base of the 
mandibles, and not reaching near to the base of the head. Antennz slender, rather 
long, and club small ; first article large, and swollen in front, nearly as large as the club; 
* By far the greater number of the specimens of the species of this genus and Orthogramma which have come 
to Europe were collected by Mr. Wallace, and in almost every one of them the thorax appears hollowed and cup- 
shaped, the elytra curled-in longitudinally or sloped to the suture, and the abdomen longitudinally hollowed ; neverthe- 
less, as I find that this is not the case in one or two examples of the less rare species which I have received from other 
hands, but that they are merely flat, I am led to suppose that Mr. Wallace had obtained his specimens shortly after 
they had left the chrysalis and while still retaining marks of immaturity. Consequently I have assumed that these 
hollowed specimens would be flat in their normal condition, and have so treated them.
