lateribus subrectis, anterius angustato, basi rotundato, angulis posterioribus obtusis ; 
elytris subopacis, coriaceis, punctis obsoletis. Long. 114, lat. 5¢ m.m. 
This is another very distinct species of which I have seen but a single individual, 
a female. The upper surface including the head and thorax is densely coriaceous. 
The dark colour of the legs and antennze, and the absence of pale spots on the vertex 
are also important characters. 
Found by Dr. Millingen either in Syria or Mesopotamia. 722. 
665. Agabus abnormicollis, Ballion, Bull. Mose. XLHI, p. 329.—Oblongo-ovalis, 
niger, nitidus, subleevigatus, elytris pone medium guttula testacea, antennis rufis, 
pedibus piceis ; prothorace elytris evidenter angustiore, lateribus subrectis, angulis 
posterioribus obtusis. Long. 9, lat. 5 m.m. 
This species has the elytra considerably broader than they are in Agabus 
cephalotes. I have only the male before me, the basal joimts of the front and 
middle tarsi, are slightly incrassate and furnished beneath with glandular hairs, the 
claws are quite simple.

666. Agabus maderensis, Woll., M.C.—Oblongo-ovalis, subtilissime reticulato- 
punctatus, piceus, supra fusco-brunneus, anteanis pedibusque rufis; prothoracis 
lateribus subrectis, angulis posterioribus rectis ; elytris seriebus minus regularibus 
punctorum numerosorum. Long. 8, lat. 4 m.m. 
This species allied to Dytiscus guttatus (No. 670) is smaller, and is readily 
distinguished by the much more numerous punctures on the elytra. The male is 
more shining than the female, and the reticulation of the elytra is excessively 
indistinct in it. The basal joints of the front and middle tarsi are but little 
incrassate, and the anterior claw of the front ones is nearly simple, being slightly 
thickened, and with its lower edge a little sinuate.

667. Agabus (Gawrodytes) intersectus, Crotch, Tr. Am. Ent. Soc. IV, p. 419.— 
Oblongo-ovalis, anterius angustulus, niger, supra genescens, nitidus, antennis rufis, 
pedibus piceis; prothorace basi elytris angustiore, lateribus leviter obliquis, 
lenissime curvatis, angulis posterioribus rectis; elytris densissime sat fortiter 
reticulatis. Long. 8, lat. 4 m.m. 
I have seen only one female of this species ; Crotch says the male has the anterior, 
claw of the front tarsi dentate.
