SOME GUATEMALAN ORTHOPTERA, WITH DESCRIPTIONS 



OF FIVE NEW SPECIES. 



Lawrence Bruner. 



The twenty-eight species of Orthoptera reported in this paper 

 were collected during the winter of 1905 by James S. Hine, 

 of Columbus, O., who referred them to the writer for determina- 

 tion. Although the collection is but a small one it is very inter- 

 esting since it contains specimens of at least four species which, 

 appear to be new to science and others that materially extend, 

 the range of known forms. One of the new species, Cornops 

 scudderi, adds a South American genus hitherto not reported 



for North America. 



Family Blattidae. 



1. Pseudophyllodromia venosa Sauss. This insect is represented by sl 



single specimen taken at Mazatenago, February 3. 



2. Blabera trapezoidea Burm. A single male of this large cockroaclx 



was collected at Santa Lucia February 1. 



Family Mantidae. 



3. Stagmomantis dimidiata Burm. The species is represented by a fine 



male which was captured March 5, at Puerto Barrios. A fe- 

 male nymph that was taken at San Jose on February 5 is also 

 referred here. 



Family Gryllidae. 



4. Oecanthus nigricornis Walk.(?) The collection contains two inales of a 



tree-cricket which were taken on February 7, at Amatitlan. One 

 of these has the greater portion of the antennae pale testaceous 

 instead of black, as described by Walker. Both, however, lack 

 the black lines or dots on the two basal antennal joints, thereby 

 agreeing with the insect that Henri de Saussure takes to be Walk- 

 er's nigricornis, but perhaps erroneously, as the types of Walker's 

 insect came from Illinois. 



5. Oecanthus varicornis Walk.(?) A single female with the two basal 



antennal joints unifasiate with black, but otherwise agree- 

 ing very closely with the preceding, is referred here. It was taken 

 at t\ e same time and place with them. 



6. Paroecanthus aztecus Sauss. The single specimen, a female, of this 



species comes from Gualan where it was captured on March 3. 



Family Locustidae. ' 



7. Hormilia tolteca Sauss. Three specimens, two males and a female, 



are at hand from ^. azatenango. They were collected Februarv 3. 



8. Orophus conspersus Brunn. A single female of this species was taken 



at I\. azatenango on February 8. 



9. Orophus tessellatus Sauss. A single female taken February 2, is 



labelled as coming from Santa Lucia. 

 10. Eriolus consobrinus Sauss. et Pict. On February 1, a female of this 



s] ecies was taken at Santa Lucia. 

 n. Thysdrus infirmus Sauss. et Pict. The collection contains a pair of 



tl is delicate species. They come from Mazatenango, and were 



captured February 3. 

 12. Idiarlhron atrispinum Stal. The insect before me is a little large as 



compared with the measurements given in Brunner's monograph, 



of the Pseudophyllidae, but it agrees in other respects with Stal's 

 ■^ Meroncidius atnspinosus. It comes from Santa Lucia, where it 



was taken February 1.
