594 H. S. GORHAM 



A considerable number of specimens were obtained. 

 In the females the elytra are generally a little infuscate at 

 their apexes. 



3. Silis fossulatus, n. sp. 



Rufo-iestaceus, subnilidus; antennis, palpis, gemculis, tihiis tar- 

 sisque fuscis^ prothoracis disco postice profunde fossulato, utrinque 

 elevalo. Long. 8-10 millim. (/ 9 • 



Mas, prolhorace subquadrato, laterihus sinualis juxla angulos 

 posticos processu duplici, inter se excisionem quasi praebente. Abdo- 

 vninis segmento ultimo ventrali fissura mediana utrinque acute mu- 

 cronata, dorsali bilobato. 



Hab. Abyssinia, Scioa: Let-Marefia, Mahal-Uonz {Antinori). 



This species is allied to the last but is wholly yellow with 

 the exceptions given above. The male characters are also diffe- 

 rent, being of the character found in certain Central American 

 species e. g. Silis praemorsa and ^. haematodes (Gorh. Biol. Centr. 

 Am. 1881, vol. Ill, pt. 2, p. 93, t. VI, f. 2). The curious pro- 

 cesses however in this species are close to the hind angle, but 

 are above and independent of the real angle ; viewed from be- 

 low a simple « nick » is seen. The abdominal structure is also 

 very remarkable. This appears to be a common species. 



4. Silis Beccarii, n. sp. 



Flavo-testacea, subnitida; capitis basi, antennis, palpis, pectore, 

 pedibus (basi exceptd) , elytrorum triente apicali, segmentisque dor- 

 salibus abdominis nigro-fuscis. Long. 7-10 m,illim. d^ 9 • 



Mas, antennis, corporis longitudine leviter serratis; prothoracis 

 margine laterali ante angulos posticos minute plicato-inter rupia; 

 segmento apicali ventrali fisso. 



Femina, prothorace latiore, antennis brevioribus, abdominis seg- 

 mento apicali medio laevi, subelevato, ad apicem minute inciso. 



Hab. Abyssinia, Bogos: Ansaba, Keren (Beccari). 



This species differs from those proceeding it, not only in co- 

 lour, but in the very small incised notch just before the hind 

 angles of the thorax in the male. The head is yellow in front
