OBSERVATIONS ON SOME NEW ORTHOPTERA. 211 



succeed in finding two specimens exactly alike. They are either 

 of a dark dirty or clay colour, or more often of a light bluish or 

 pink, and, to such an extent do all resemble the bluish, pink, &c., stones 

 abundantly scattered about the field, that even at close range the 

 insects could not be distinguished. In connection with this striking 

 resemblance between the colouring of the insect and the objects upon 

 which they rest, there is a perceptible immobility of the described 

 orthoptera. Only when the foot of the pedestrian threatens to crush 

 the insect does it make a leap, then it remains at rest again, when its 

 colour blends with that of its surroundings and again becomes 

 imperceptible to the eye. 



Freiiiubia (jrandis, n.sp., is from 1-3-1 "5 in. long. The males being 

 shorter and thinner than the females. From these dimensions we see 

 that this species belongs to the very large Kreniobicfe. In order to 

 make the specific characters of K. (p-andis more conspicuous I will give 

 a comparative description of the different parts of the body of this 

 species with the similar pai'ts of another very common form, i.e., E. 

 )iu(rnata. Except in the difference in size the heads of both are almost 

 exactly alike in shape. The essential difference is noticed in the shape 

 of the epicranium, i.e., the distance between the eyes ; in K. iiiandis 

 it is slightly truncate, while in K. imnirata it is broader and marked 

 by many raised lines. The pronotum presents the most important 

 character of the species. As in 7V. iiiiirirata it consists of two parts; 

 the anterior, separated from the posterior by a transverse sulcus, is in 

 its turn crossed by three sulci (as in K. iiniricata) dividing it into 

 three parts, each of which terminates above in a tooth (exactly as in 

 K. Iiniricata). These three divisions, narrowing dorsally, conjunc- 

 tively form an elevated sharp ridge or crest which runs along the 

 middle of the anterior half of the pronotum, and is divided into three 

 teeth that are not equally distinct in all specimens. This anterior 

 half of the pronotum of /'.'. (jirDKlis, as in /*-'. imirirata, is granulous 

 and thickened, but differs from K. iiniricata in that the teeth of the 

 elevated crest are raised one above the other, in which case the first 

 (the one nearest the head) is lower than the third, while in A', iiniricata 

 the third is lower than the first two which are almost etpial in length. 

 More important as a differentiating character is the posterior part of 

 the pronotum. In /■,'. imnicata this part is sharply separated from the 

 anterior by reason of its being almost flat above with but a slight 

 longitudinal ridge in the middle. J>esides, this part of the pronotum 

 in 7'.'. Iiniricata, even though it becomes narrower posteriorly, termin- 

 ates in a rounded angle almost entirely flattened, while in A', (iraiulis 

 this part of the pronotum is entirely different in structure, l^egin- 

 ning with its end the pronotum gradually curves upwards, and near 

 the middle runs into a raised crest with a sharp edge, which continues 

 to the posterior end of the pronotum that here forms an acute angle. 

 Thus the crest of the anterior half of the pronotum of K. (jrandis. 

 gradually passes into the raiseil crest of the posterior part, in conse- 

 (pience of which, the division between the anterior and posterior parts 

 of its prothorax is not as distinct as in A', iiniricata, and the sharp 

 posterior end of the pronotum increases the difference between the two 

 species. It should also be mentioned that the thorax of l\. iirandia 

 is covered with small tubercles as in /•.'. iiniricata. Of other plastic 

 characters and differences one may be noticed in the structure of the
