512 MEDICAL ENTOMOLOGY 



punctated. Its colour is like that of rotundatus, dark ferruginous 

 ochre. This species has been recorded from the common pipistrelle in 

 England and from a bat in South Africa; it has been taken from 

 Scotophilus kuhli in South India. 



Cimex boueti, Brumpt. This species was found by Bouet in French 

 Guinea, where it is said to suck the blood of man; Brumpt figures both 

 sexes in his Precis de Parasitologie, pp. 563, 564. The prothorax is 

 quadrilateral in shape, the anterior angles hardly if at all produced and the 

 sides not reflexed. The abdomen is ovoid in shape and the elytra 

 are rudimentary ; the body is only sparsely covered with hairs. The 

 biology of this species has been described in a recent paper by Joyeux 

 (see Appendix). 



GENUS LOXASPIS, ROTHSCHILD 



Reflexed margin of pronotmn very narrow. Scutellum transversely 

 oblong, produced into a small point in the centre of the hind margin. 

 Elytra transverse, widest towards the suture. Tibia with a pseudo-joint 

 at about four-fifths of the length. 



Loxaspis mirandus, Rothschild. This bug has recently been described 

 by Rothschild, as follows : Head, thorax, elytra, abdomen and legs 

 densely covered with very fine hairs inserted in pits; colour dark brown. 



Head (without labrum) one-fifth shorter than the pronotum. Pro- 

 notum at apex not sinuate, almost truncate, and of equal width 

 throughout, the sides being slightly incurved; anterior angles slightly 

 produced but not reaching half-way towards the eye; posterior edge also 

 truncate ; explanate margin narrow, slightly reflexed and of the same 

 width all round except at the apical angle, where it is very slightly 

 widened. All the tibiae possess a pseudo-joint at about four-fifths of 

 their length. According to Rothschild this is a very distinctive character, 

 and is not known in any other species of the Cimicidae. Length, 4 mm. 



This bug was found in a house in Kilindini near Mombasa, and is 

 probably parasitic on the bat Taphozous hildegardeae. 



Of the other genera of the Cimicidae, Cacodmus is found in South 

 Africa, Oeciacus in Europe and North America and Haematosiphon in 

 Central America ; it is not known whether the species belonging to these 

 genera are blood-suckers or not (see Appendix). 



FAMILY POLYCTENIDAE, GIGLIOLI 



Small (3 mm.) very aberrant bugs closely allied to the Cimicidae. Head 

 triangular in shape and articulated to the thorax by means of a
