American species often prove the material to be misidentified or 

 mislabelled. We would be inclined to commend the series of 

 measurements given for each species discussed, but when we con- 

 sider the lack of care, errors and ignorance of geographic essen- 

 tials and the host of clearly inadequate descriptions, we naturally 

 fear that the measurements have been compiled in the same man- 

 ner. As a whole, we can definitely state that the " Insektenfamilie 

 der Phasmiden" is the greatest retrograde step made in recent 

 years, away from true scientific study of the order Orthoptera. 



Bostra*^ colombiae new species (Plate XXII, fig. 5 and 6.) 



This species shows nearest afl&nity to B. incompta Rehn.^' The 

 differences in the male genitalia are very decided, however; the 

 lateral portions of the eighth dorsal abdominal segment being 

 hardly at all produced ventrad, the operculum not as deep and 

 more evenly and broadly convex distad. The head, pronotum, 

 mesonotum, metanotum and limbs are all slightly but apprecia- 

 bly more elongate and attenuate than in incompta, the length of 

 the median segment approaching slightly more closely that of 

 the metanotum. 



Type. — cf ; San Antonio, Cauca, Colombia. Elevation, 6600 

 feet. December, 1908. [United States National" Museum.] 



Size large; form very slender and elongate; surface smooth but not glabrous 

 as in incompta. Head moderately elongate; eyes circular, length contained 

 twice in cheek; occiput smooth, unarmed. Pronotum nearly twice as long as 

 broad. Median segment only a little shorter than metanotum. Sixth dorsal 

 abdominal segment broadening slightly caudad, distinctly shorter than fifth; 

 seventh with sides parallel, half as long as sixth; eighth slightly shorter than 

 seventh, with sides produced ventrad no lower than sev^enth, its median por- 

 tion slightly pinched and more strongly convex, lateral margins almost straight. 

 Ninth (distal) dorsal aljdominal segment small, with length equal to width, 

 surface convex except di.stad where it is weakly bi-impressed, lateral margins 



"- Redtenbacher has described twenty-five new si)ecies of Bo.slrn in the "In- 

 sektenfamilie der Phasmiden," entirely without figures. Though the asso- 

 ciation of sexes is extremely difficult, conscientious effort to do so on the part 

 of that author would have secured much better results. The overlooking of 

 B. jugaii.s Rehn has resulted in the erection of two synonyms: amplectens 

 described from the male, loiuico perculatn from the female. A Costa Rican 

 pair of this species, still in coitu, establishes definitely this sex association. 



"■'In the Philadelphia collections are a paratypif male and an additional 

 Costa Rican male.
