d" $ . A single pair in the collection agrees well with C. ies- 

 quorum Wagn. (1893), except in the details mentioned below. 

 The new species is smaller and paler than C. tesqnoriom and bears. 

 on the whole, fewer bristles. The rostrum reaches a little beyond 

 the trochanter in both sexes and is therefore longer than in the 

 species mentioned. The abdominal sternites III to VI have each 

 a row of 6 bristles on the two sides togethei-, the 2 bearing one or 

 two additional bristles on e;ich side of the sixth segment. The 

 hind femur has on the outside one ( c? ) or two ( $ ) lateral bristles in 

 the basal half and a subventral bristle before the apex, and on 

 the inner side a row of 8 or 9 bristles. The hind tibia, which has 

 a double row of about 1 1 bristles on the outer surface in C. tes- 

 qiiorum, has only 8 lateral bristles in C. mongolicus inclusive of 

 the apical one. The first mid-tarsal segment is distinctly shorter 

 than the second.

Clasping organs of Ceratoj)hi/lh(s mouijulicus ^ , 



The differences in the male genitalia are slighter than they 

 generally are in distinct species, The non-movable jirocess of 

 the clasper (text-fig. 114, P) is a little slenderer than in C. tes- 

 qu,orum. The finger (F) is triangular as in that species, and bears 

 the same bristles, but it is less widened at the apex, the upper 

 ( = apical) margin being one-fourth shortei- than in tesquorwm, 

 the proportions of length and width of the finger being 7 : 4 in 

 mo7byolicus and 7 : 5 in tesquorum. The eighth stei'nite of tesqiwru'ni 

 is provided with 5 bristles and a thin hair, the bristles being
