illation of it revealed the followin<2: differences: The Guatemahin ex- 

 ample lias no gro'.md sculpture on the back of the head, has the elytra 

 more irregular, almost sculptured, and the elytral punctures in irreg- 

 ular grooves but scarcely evident. This specimen was probably the 

 basis for the Guatemalan record in the Bernhauer and Schubert 

 catalog. 



The specimens recorded from Martinique by ISIarshall as fhoracicus 

 Erichson are undoubtedly not that species but the present one. 



I find no record of the habits of this species. 



3. PAEDEKUS JAMAICENSIS, new species 



Paederus jamaicensis Beenhauer, MS. 



Description. — Rufotestaceous throughout. Head with eyes a little 

 broader than long; without punctures except for a few large setiger- 

 ous ones; with rather indistinct ground sculpture; labrum with a 

 moderate triangular notch at center, edge somewhat crenate. Prono- 

 tum about one-sixth longer than wide, widest at anterior third, feebly 

 narrowed behind; with a few setigerous punctures especially at the 

 sides. Elytra at apex as wide as pronotum, closely appressed to 

 body and much narrower at base; with about 10 large setigerous 

 punctures; the surface uneven but not distinctly sculptured. Abdo- 

 men with about 10 large setigerous punctures on each segment ; with 

 very vague transverse ground sculpture. Male, unknown. Female-^ 

 eighth sternite prolonged into an acutely triangular process. Length, 

 6 mm. 



Tyjye locality. — Jamaica. 



Types. — Holotype, female, in the British ]\Iuseum. 



Records. — The following is the only record known to me : 



Jamaica: (British Museum ace. 45.110). 



Specimens examined. — I have seen only the unique tj'pe. 



Remarks. — ^This specimen seems so very distinct from all other 

 species of Paederus known from the AVest Indies that I describe it in 

 spite of the chance that it is immature. It certainly does not belong 

 to any of the other species listed here. It belongs in the subgenus 

 Neopaederus. 



I find no record of its habits.
